In recent days, the traffic police team number 11, the City Police. Hanoi constantly deploys troops, especially at peak hours to separate traffic, guide, as well as handle cases of motorbike drivers entering Thang Long Boulevard. According to the reporter’s actual record, the above violation is very common in the early morning rush hours and late afternoon rush hours. Notably, when asked, violators all said they knew about the above ban. However, because of hurry, forgetting, fear of traffic jam…so “missed” to go in. “I came home from the inner city of Hanoi in Thach That, when I turned onto Thang Long Boulevard, the road for motorbikes was blocked, so I went into the car lane. I knew this was a forbidden road, but I was afraid of traffic so I went in the wrong lane. With full vehicle papers, I was fined 2.5 million VND and temporarily seized the vehicle”, said Ms. expressed regret. Similar to the case of Mr. H. (Thach That’s family) said, this is the first time he entered the forbidden road, the reason was also because the lane for motorbikes was blocked. “I was fined 2.5 million dong and impounded the car. In the next few days, I am thinking of borrowing a motorbike to go to work, I am very sorry for the violation, “said Mr. H. All violators will be recorded, and vehicles will be impounded. When motorbikes and rudimentary vehicles enter the lane for cars, there is still a lot of potential for accidents, because the speed of travel for cars is very large. In fact, there have been many serious traffic accidents that occurred when motorbikes went to the wrong part of the road on this boulevard. Talking to PV, Senior Lieutenant Dinh Ngoc Hai (Traffic Team No. 11, Traffic Police Division of Hanoi City) said that the unit has continuously launched propaganda, rectified and handled violations. In the process of handling, the majority of vehicle drivers obey the orders of the traffic police, but there are also people who do not obey, ready to turn the vehicle, speeding and recklessly overtaking to avoid the task force potentially dangerous traffic. It is known that the above violation will be administratively sanctioned from 2 to 3 million VND, stripped of driving license for 4 months and temporarily impounded the vehicle for 7 days. Therefore, to ensure the safety of road users, it is necessary to consciously obey the regulations.

This is considered the largest airspace crossing of China that Taiwan has recorded so far. Although there has been no comment from Beijing, according to Reuters, this information comes after G7 leaders issued a joint statement last Sunday in which they criticized China for a series of issue, emphasizing the importance of peace and stability in the Taiwan Strait. Beijing later condemned the joint statement as “defamation”. Over the past several months, Taiwan has continuously released information about a series of incidents of Chinese air force entering its airspace, mainly concentrated in the southwest area of ​​the air defense identification zone. The most recent incident involved 14 J-16s, six J-11s, and four nuclear-capable H-6 bombers, along with anti-submarine and electronic warfare aircraft. and early warning; according to the Taiwan Defense Agency. The incident has just been reported to be the largest-scale incident since Taiwanese authorities began publicly reporting violations of their ADIZ since last year, breaking the previous record of 25 Chinese aircraft. entered Taiwanese airspace on April 12. Taiwan’s Defense Ministry added that its fighter jets were deployed to intercept and repel the Chinese aircraft, while missile systems were deployed at the ready. The Chinese Ministry of National Defense has not yet commented on this information. China has previously asserted that such missions are necessary to protect the country’s sovereignty and deal with “collusion” between Taipei and Washington. The United States, like most countries that do not have formal diplomatic relations with Taiwan, keeps a close eye on events that raise tensions with Beijing.

(Source: Reuters) Sumitomo Corp. (Japan) will provide mobile service in Ethiopia through a consortium with a telecommunications service provider Vodafone Group (United Kingdom). The move will make Sumitomo the first Japanese company to enter the African market. Ethiopia has approved a license for the consortium on mobile service providers in the country. It is expected that Sumitomo will hold about 30% of the shares in the new business and invest about 8 billion USD in 10 years, including investment capital for base stations. This will be the largest foreign direct investment on record in Ethiopia. According to the plan, service delivery will begin in 2022.

In addition to mobile services, the consortium also plans to launch services in areas such as digital currency, education, and health information technology. The announcement of the cooperation between Sumitomo and Vodafone comes amid concerns in Japan, the US and the UK about the trend of Chinese companies such as Huawei Technologies and ZTE building much of Africa’s telecommunications infrastructure.

Google Chrome 90 on macOS and Linux does not appear to be affected. Photo: MINH HOANG A Google product expert seems to have identified the problem. “It seems that this issue is related to the User Data folder of the computer, so using Google Chrome (beta) should solve the problem.” However, if you just want to use the stable version of Google Chrome, you can follow these steps to prevent problems. First, close the browser and press the Windows + E key combination to open File Explorer, then paste the %LOCALAPPDATA%GoogleChromeUser Data link in the address bar and press Enter. Next, delete the Local State file, then reopen the Google Chrome browser. If the problem is still not fixed, the user can simply go back to %LOCALAPPDATA%GoogleChromeUser Data, copy everything here to another place, such as the Desktop. Then, rename the User Data folder to any name (different from the old name) and reopen the Google Chrome browser. Currently Google has confirmed the issue, and it will probably be fixed in the near future through a new update.

French photographer Jeremy Buchholz didn’t have the money to buy an apartment in Bordeaux, so he decided to buy an abandoned garage and turn it into a great hideaway. This old garage has a big corrugated iron door and inside is a messy, dirty room. So, Jeremy Buchholz called his friend architect Matthieu de Marien, who specializes in renovating shops, offices and other spaces into homes. The front of the garage was formerly a rusted white corrugated board and has now been replaced with a sturdy sliding wood panel. Stepping into the house, you will gasp in surprise. The living space is very cozy and beautifully decorated, different from the outside. To make the space feel larger, De Marien created a “home within a house”: a large piece of furniture that includes a small bathroom, bedroom, desk, wardrobe, chair sofa and storage. All space is designed in this large furniture box. The rest of the house is open plan with kitchen, dining area, living room and front yard. Indoor skylights both bring in more natural light and create a more open feel.

In fact, in recent years, the changes faced by the auto industry are not only the tide of smart electrification, but also changes in the automobile consumption structure-the younger car buyers and the increase in the proportion of women buying cars. As early as 2019, the Travel Association stated that people born in the 80s and 90s have gradually become the main car-buying group. And with the improvement of women’s social status, the proportion of female users in car purchases is gradually increasing. According to big survey data, in 2020, women’s car purchase consumption will reach 22.28%, which has exceeded that of men (22.00%). This is the first time in the past ten years that women spend more on buying cars than men, and women buying cars tend to be younger, with the largest number of women aged 26-35. Great Wall Motors has already targeted this market that few car companies pay attention to. On August 20, 2018, Great Wall Motors officially released the Euler brand. Euler is positioned as a car brand that prefers women. The first model, the Euler iQ, was officially launched at the Chengdu Auto Show that year. At this Shanghai Auto Show, Oula Motors held a special press conference with a cute style. There were also traffic actor Zhang Binbin and popular actress Mao Xiaotong to help out. Source: Euler Motors At this Shanghai Auto Show, Euler Motors launched a variety of new cars, but the most concerned is the Euler Lightning Cat and the Euler Punk Cat. Euler Lightning Cat accelerates from zero to 100 kilometers in less than 4 seconds, has frameless doors, hidden door handles, automatic lifting tail, equipped with L3+ level automatic driving assistance, full-scenario intelligent automatic parking, ORA multi-mode integrated supercomputing platform, ORA exclusive Omnidirectional super-sensing system, Qualcomm’s third-generation intelligent platform, V2X Internet of Everything, etc. It is understood that the Euler Lightning Cat released by Euler Motors this time is its first pure electric super sports car model, which will be sold globally and is expected to be priced at 30,000 US dollars and less than 200,000 yuan. Another brand-new Eulerpunk cat continues the retro aesthetic design idea. Its appearance is similar to the original Volkswagen Beetle. The front face part adopts a design style similar to the Euler Goodcat. The round headlights are very eye-catching. Yu Fei, general manager of Great Wall Motor’s Euler brand marketing, said that among the models that have been released and are already on sale, the price of the punk cat is the highest, which stretches the brand’s tone and overall brand positioning. It will be listed in the first half of this year. Judging from the on-site reaction of the press conference on the 19th, many senior media professionals believe that the two new products launched by Euler are very outstanding in appearance and have the most basic conditions to attract female consumers, or can help Euler Motors to further its sales. On the probe. Source: Euler Motors It is understood that the sales volume of Euler Automobile reached 17,634 in the first two months of 2021, second only to Wuling and Tesla, ranking third. At the beginning of April, Wei Jianjun, chairman of Great Wall Motors, said when attending the event that Great Wall Motors’ electric vehicle brand Euler is expected to surpass Tesla in sales in 2023. But it is worth noting that Euler’s models are mainly concentrated in the low-end car market of 60,000 to 150,000 yuan, and high cost performance is its main competitive advantage. In the mainstream price range of 150,000 to 250,000, Euler Motors has no products before. The launch of Euler Lightning Cat and Euler Punk Cat will help Euler Motors cover this price range. But whether consumers will buy it depends on the market response.

The reporter learned from the Beijing Botanical Garden yesterday (18th) that more than 100 varieties and more than 200,000 tulips in the garden have entered the best viewing period, and a flower sea landscape has been formed in an exhibition area of ​​about 4000 square meters on the west side of the Science Museum. The flower viewing season in the garden will last until April 25th.

According to the staff, at present, colorful pictures can be seen everywhere in the tulip exhibition area in the park. In the exhibition area, colorful and gorgeous tulips spread out, or red or pink peach blossoms cover it, tall poplar trees obscure the sky, and the green hills in the distance are verdant, and people walk in the scene, like walking in the middle of a painting.

The theme of this flower show is “Flowers blooming, wealth and good luck”. Gardeners use tulips to present traditional Chinese shapes that imply auspiciousness and wealth, such as peacocks, ruyi, and peony flowers. The exhibition is divided into four zones A, B, C, and D. Zone A is dominated by the magnificent peony shape, Zone B is dominated by the auspicious peacock shape, and Zone C and D are connected by a ruyi shape. It shows people’s yearning for a better life, and also shows the prosperity and strength of the motherland.

The Tulip Flower Show in Beijing Botanical Garden has been held for many years. Compared with the relatively single display methods such as large color blocks and large ribbons in the early days, the botanical gardens have begun to prefer more abundant display methods such as beautiful shapes and smooth lines in recent years. Pay attention to collocation with lawn and other bulbous flowers such as hyacinth, daffodil, fritillary, etc.

In addition, the botanical garden also enriches the landscape effect by constantly updating tulip varieties, such as the pink flower “Kelly”, the white flower and yellow edge “Burning Evita”, and the red flower “Teddy Bear”, all of which make their debut this year. exhibition.

At present, during the 33rd peach blossom viewing season of the Beijing Botanical Garden, in addition to tulips, nearly a hundred (including varieties) of spring flowers such as peach blossoms, begonias, and lilacs in the park have now entered the viewing period. Together to show the most beautiful spring, it is an ideal place for citizens and tourists to enjoy the spring. Reporter Ye Xiaoyan Correspondent Wang Xin Photo by our reporter Wu Di

According to records, this is the settlement of the 27th descendant of Zhuge Liang. This village was also the largest residence of descendants of Gia Cat in the mid and late Yuan Dynasty.

Why is this Zhuge village said to be the first strange village in China? There are three reasons for this.

First, the vast majority of villagers are descendants of Zhuge Liang, a talented prime minister and military man during the Three Kingdoms period. In other words, almost everyone in the village has the surname of Zhuge Liang or is married to the Zhuge family. There are very few people who are not members of the Zhuge clan.

According to a statistic from the 7th Zhuge Liang Workshop, there are about 16,000 descendants of Zhuge Liang in China. Of these, a quarter (about 4,000 people) live alone in Gia Cat village.

Second, this village is still strange in its subtle and mysterious layout.

Looking down from above, the whole arrangement, distribution of houses, to the alleys in the village all coincide with the Bat Mon map of Zhuge Liang in history.

The topography of Gia Cat village is arranged in the middle of low and flat, the surrounding ascending. Water flows from above and converges in the central area, forming a pond.

This pond is a special feature of Gia Cat village, which is also the starting place for the Bat Battle. The pond is not big, but inside there is water, outside is earth, and has the same shape as Tai chi in the Bat Monster. What a strange thing.

Centered on the pond, there were eight alleys open in all directions, leading directly to eight high mounds outside the village.

In the village, there are also many narrow alleys connected horizontally, in the alley there are thousands of households, many ancient houses are scattered among the alleys.

The alleys near the central pond are at first relatively straight, then gradually fold and expand to the outside. Besides, there are many alleys that are connected vertically and horizontally, which looks like a maze.

It is difficult for outsiders to enter alleys, and even get lost. Therefore, for hundreds of years, no one has dared to enter this village. It has become a secluded place from the world.

Interestingly, the descendants of Zhuge Liang who have lived here for hundreds of years also do not realize the magic of this layout. It was not until the relevant records were found in an ancient book that everyone was at this point.

On April 2, the China Securities Regulatory Commission’s website issued the “China Securities Regulatory Commission’s Market Banning Decision (LeTV, Jia Yueting and other 15 responsible entities)”.LeTV and LeTV’s actual controller Jia Yueting will be fined 240.6 million yuan and 241.2 million yuan respectively for ten consecutive years of financial fraud and fraudulent issuance. Among them, Jia Yueting and Yang Lijie will also be sentenced to life-long securities market bans by the China Securities Regulatory Commission. Into measures.

Speaking of LeTV, you can’t get aroundJia Yueting, the man of the year, once expanded wildly in the name of dreams and built a business empire with a market value of 170 billion. In the end, he became the spokesperson of “suffocation for dreams”, and only one remained. The legend of “return home next week”.“Seeing him getting up from the Zhu Tower, seeing him banqueting guests, seeing his building collapsed” is just right for Jia Yueting and his LeTV.

Jia Yueting, a visionary liar

From the perspective of character, Jia Yueting’s financial fraud, non-fulfilment of loan commitments, and fraudulent issuance of stocks; from the perspective of winners and losers, Jia Yueting’s current situation can only be regarded as a veritable “Kou”; butJudging from his previous vision and layout, we have to admit that Jia Yueting is a very far-sighted person.

Jia Yueting founded LeTV in 2004, followed by fighting KuaiBai, buying copyrights, and listing LeTV on the GEM in just 6 years. Regarding the importance of copyright, I believe everyone has already experienced it. Xiaolei now encounters copyright issues when listening to a song or watching a video on a certain platform.

LeTV’s ecosystem covers seven major sectors: content, TV, mobile phones, automobiles, sports, the Internet, and cloud. Its “platform + content + terminal + application” ecosystem is called the “LeTV model” by the industry. From the current perspective, Jia Yueting’s layout at the time was still very forward-looking and strategic.Although Jia Yueting’s credit reputation has fallen to the bottom, the LeTV model has become the originator of the intelligent ecosystem that many Internet companies are vying to follow.

In the automotive field, Jia Yueting planned a “kangzhuang road” for the ecological development of automobiles for LeEco before 2016, compared with the “sluggish” Xiaomi and Didi. If Jia Yueting did not build a car like his present one, he should also have his top spot among the current auto giants.

So since Jia Yueting is so insightful, how could he still play this game of 100 billion yuan? In fact, the problem lies in this big game.Although the ecosystem laid out by LeTV back then showed Jia Yueting’s advanced strategic vision, the rhythm of his layout was completely wrong. The blind industrial expansion turned LeTV into a magnificent and crumbling loft in the sky.

Now, the era of LeTV has long passed,The first ray of life for Jia Yueting’s turnaround is also pinned on the dream of building a car that suffocates him, and his dream of building a car is currently in a state of coexistence of vitality and crisis.

Jia Yueting’s dream of building a car is coexisting with vitality and crisis

FF has already made a lot of big moves when it just entered 2021. It announced that it would backdoor listing, and it was successful in financing. After that, it has reached strategic cooperation with Zhuhai State-owned Assets and Geely, showing it to the outside world. The scene is booming.

Lack of money is the biggest problem FF has always faced, Backdoor listing means that FF will be able to obtain more funds in the future, Which can make its car-making business complete more smoothly. The successful financing means that although Jia Yueting has long been notorious in China, FF can still be recognized by the capital market. The cooperation with Zhuhai State-owned Assets and Geely also shows that the Zhuhai government and domestic auto giants have a positive attitude towards FF, which will become a powerful boost for FF in the automotive field.

Judging from the various major moves of FF in the past six months, it seems that it has firmly grasped the three major elements of the strategy of war: the time, the right place, and the harmony of people, but in Xiao Lei’s view,The current crisis facing FF is far greater than the vitality.

first of all,The positioning of the FF 91 is too high-end. Even if it can achieve mass production next year and complete its sales target of 2,400 vehicles, it still cannot solve its urgent financial needs.You know, mass production and profitability are two different things. In the long river of automobile history, there are countless cases of suspension of models and bankruptcy of car companies due to high cost and too little output. The annual sales volume of 2,400 vehicles is obviously difficult to bring to FF. How much profit, poor gross profit margin may even further drag it down.

Of course, judging from the positioning of FF 91,The significance of its mass production is obviously not for volume, but for the hope of FF’s dream investors to see their dreams shine into reality.So, whether there are 2,400 diehard fans who will spend more than 2 million yuan to pay for FF 91 has become a key question. If FF 91 completes annual sales of 2,400 vehicles, then it may further stimulate investors to continue to spend money; but if FF 91 only sells 24 vehicles, what mentality will FF investors have?

According to FF’s model plan, its follow-up model FF81 will have to wait until after 2023 to complete mass production at the earliest, and the lower-positioned FF 71 is expected to be mass-produced by the end of 2024.These mass production plans can only be completed when FF is progressing smoothly, and it is difficult to say whether FF, which is already struggling, can survive such a long time.

In addition, FF 91 was originally planned to be mass-produced and launched in 2018. Now even if it can be mass-produced as planned, the time will have to be pushed to the first half of 2022, which means that it has been delayed by 4 years. Smart cars are developing so fast,There are already a large number of smart car giants on the market, and these giants have had the strength to equalize or even surpass the previous advantages of FF in the past four years of development.

to sum up

Finally, come back and talk about the “China Securities Regulatory Commission’s Market Banning Decision (Jia Yueting, Yang Lijie and other 5 responsible entities)” issued by the China Securities Regulatory Commission and what impact will it have on Jia Yueting’s car-making plan.For Jia Yueting, a fine of 240 million yuan is second. Anyway, he has already developed the ability to not overwhelm his debts, butThe SFC’s ban on him can make his situation even worse. He is bound to struggle in the country, and may even have no hope of returning to China from then on.

Smart Things reported on April 15 that Google recently announced the launch of AR indoor navigation function, which provides users with route guidance in scenarios such as airports, transit stations and shopping centers, and helps users find the nearest elevators and escalators, boarding gates, and platforms , Baggage claim, boarding counter, ticket office, restroom, ATM, etc.

This AR indoor navigation technology breaks through the limitations of traditional indoor navigation of flatness and low legibility, enhances image accuracy and data versatility, and not only brings users a novel and personalized experience of indoor navigation, but also provides offline navigation. Industries such as retail bring potential application value.

This article will analyze AR indoor navigation from three aspects: AR’s breakthrough in the legibility of indoor navigation maps, the transformation of AR navigation from outdoor to indoor, and the development prospects of AR indoor navigation.

1. AR breakthrough in indoor navigation: two-dimensional leap to three-dimensional, and map legibility is improved

Based on AR indoor navigation, the user’s own location and floor can be identified, and then AR overlay guidance such as arrows and information markers can be used to reach the destination.

Although these instructions seem simple, they cannot be achieved by previous indoor navigation methods such as indoor maps, Bluetooth beacon positioning, Wi-Fi signal positioning, and GPS positioning.

Indoor map is the most traditional one, such as the retrieval map of the library bookshelf. This method collects a large amount of data and makes an index map, and readers can navigate and find through the exclusive number of each book. However, the production and expression of maps for large-scale indoor environments is costly, and its universality is not high.

The Bluetooth beacon location method is more popular. Relying on Bluetooth, the smart phone software can roughly get the user’s location on the map for route planning and navigation. However, due to the short transmission distance of Bluetooth, it will have extremely high deployment and maintenance costs in large indoor environments such as shopping malls and office buildings.

Another solution is to locate and navigate based on Wi-Fi signals. However, due to the complexity of the indoor environment, Wi-Fi signals are easily changed by environmental changes, so maintenance costs are still high, and accuracy is also restricted by factors such as Wi-Fi router deployment density, environmental stability, and training duration.

Although the GPS positioning method is widely used, it has poor signal penetration and low positioning accuracy. It is only suitable for two-dimensional planes. It can determine the approximate location of the user but cannot determine the direction. It cannot play a role in large-scale buildings.

▲The GPS signal bounces off the facade of the building

The AR indoor navigation launched by Google this time is equipped with a new visual positioning system (Visual Positioning System; VPS), which can make up for the deficiencies of the above methods.

Google AR indoor navigation function (Indoor Live View) relies on VPS technology to determine the user’s indoor location, and combines the virtual route with the actual indoor scene through visual processing.

The visual positioning system VPS is different from GPS. It does not rely on signals for positioning, but on images.

First, engineers can create localized maps through VPS. This method is called simultaneous localization and mapping (SLAM). By taking a series of images with known locations and analyzing visual features, VPS can create maps and establish fast search indexes, such as buildings, bridges, etc.

Secondly, when the user needs indoor navigation and positioning, the VPS will match the camera lens view with the VPS index view, and use the mobile phone’s built-in inertial measurement unit (IMU) data such as the camera, gyroscope, accelerator, and gravity sensor to use motion Artificial intelligence algorithms such as tracking and environmental perception are compared and analyzed to determine the location and direction of the mobile phone user relative to the real world.

Finally, in terms of orientation presentation, VPS can superimpose label effects such as guidance arrows and subtitle information onto the real images collected by the camera in real time, and rely on light estimation technology to better integrate virtual content into the real world. The light estimation technology allows the mobile phone camera to perceive the current environment’s lighting conditions and perform color correction on the virtual image, thereby enhancing the sense of reality when the virtual and real images are combined.

2. The indoor transformation of AR navigation: the improvement of image accuracy and data versatility

Since 2019, Google has launched the AR navigation function (Live View). Relying on the VPS visual positioning system and Google Street View gallery, it helps users to obtain accurate navigation routes outdoors. In subsequent updates, users can also identify surrounding landmarks through AR navigation, allowing users to know their location in the city more clearly.

How difficult is it to go from outdoor navigation to indoor navigation?

Large-scale indoor scenes such as exhibition halls, museums, shopping malls, and transportation hubs are complex and large in scale, and there are many areas of untextured space and visual ambiguity. The collection, production and expression of map data is a major difficulty. At the same time, with changes in lighting and viewpoints, it is also a challenge for users to accurately and quickly relocate. Google has many technological breakthroughs.

The first technological breakthrough is the improvement of image accuracy. More than 10 years ago, Google began to introduce street view maps, where users can have a “human eye view” map browsing experience, but at first these street view data were not localized. Image data localization can add more annotative label information to pictures of objects, locations, etc., to help users quickly understand.

In order to use VPS to achieve global localization, Google uses information collected and tested from more than 93 countries around the world to connect it with Street View data. This rich data set provides trillions of powerful reference points through triangulation to help people more accurately determine the location of devices and guide people to their destinations.

▲Google triangulation method to accurately locate buildings

Although this method works well in theory, there are still challenges in practice. The problem is that the real-time image of the mobile phone may be different from the scene when the street view is collected during localization. For example, the details of trees will change with the seasons, or even with the magnitude of the wind, and a good match cannot be obtained.

In order to break through this technology, Google uses machine learning to filter images of temporary and changeable things in the scene, focusing on images of fixed structures in the scene. This technological advancement also makes today’s AR indoor navigation more accurate.

Another technological breakthrough is the rapid acquisition of data.

Airports, shopping malls, hospitals… The numerous buildings mean that Google needs to shoot a large number of indoor images of public scenes. In the previous outdoor street view database construction, Google has gradually improved its image collection methods from early street view vehicles, street view tricycles, street view trolleys, and then to the convenient and lightweight street view backpack (Trekker).

▲The old street view backpack on the left and the new one on the right

Below the street view backpack is the main body of the backpack, and the top is a spherical device equipped with 15 5 million pixel cameras. With this kind of backpack, image collectors can take pictures of corners where cars can’t get in.

As a result, in the image collection of indoor public scenes, Google can use its own street view backpack to send a large number of contractors through an airport, station or shopping mall in a certain place to quickly capture VPS data.

Google said that AR indoor navigation will first be launched in some shopping malls in Chicago, Long Island, New York, Los Angeles, Newark, New Jersey, San Francisco, San Jose, California and Seattle. In the coming months, it will also be launched at airports, shopping malls and transit stations in Tokyo and Zurich.

However, there are still some weak links in the development of AR indoor navigation, such as focusing on product development and landing but insufficient understanding of users and functional requirements, map information expression pursuing visualization and realistic effects but lacking purpose and rationality, and related hardware for presentation applications. Development is lagging behind and so on.

3. The development prospects of AR indoor navigation: scene expansion, use increase, equipment extension

At present, AR indoor navigation technology is accelerating its development. In addition to Google, domestic Baidu and AutoNavi are also exploring technology research and development and application scenarios.

Take Baidu as an example:

In November 2016, Baidu launched the AR walking navigation function. The navigation interface includes elements such as compass, route, turn indicator, way point and destination bubble, roller guidance enhancement, route overview, etc., with voice reminders to enhance the user’s walking navigation experience. In April 2017, Baidu added “Tutu”, an AR navigation cartoon character, to enhance the fun of AR guidance through big-eyed cute objects. In December 2020, Baidu Maps and Baidu Brain DuMix AR-visual positioning service platform launched the AR indoor navigation function-AI indoor communication.

AI indoor communication provides users with high-precision 6DoF positioning capabilities through visual positioning and augmenting service (VPAS). VPAS technology uses image-based 3D reconstruction technology to construct high-precision geometric maps of shopping malls, and then uses scene understanding algorithms and 3D vision positioning algorithms to calculate the user’s accurate location in real time. The actual position accuracy can reach 1 meter in the actual complex environment. Currently, scenes such as Beijing Qinghe Wanxianghui, Beijing Shuang’an Shopping Center, and Shanghai 2049 Emerald Park Shopping Center have been launched. At the same time, the technology can also be used in scenarios such as industrial inspections and logistics sorting.

Although AutoNavi and Sogou are relatively mature in outdoor walking AR navigation and in-vehicle navigation technology, they have not yet found their involvement in AR indoor navigation.

In addition to major map factories, SenseTime is also exploring AR indoor navigation. The SenseMARS Mars Mixed Reality Platform of SenseMARS, jointly built by Zhejiang University-Shangtang Technology 3D Vision Joint Laboratory and SenseTime Product Team, uses sparse point cloud map technology to reconstruct high-precision 3D maps, and calculates the current device’s 6DoF pose through IMU sensors. , Combined with SLAM technology to achieve indoor accurate positioning and AR navigation.

In the future, relying on the development of AI and IoT technologies, AR indoor navigation will allow users to see the digital attributes of the physical space, such as store virtual signs, promotional information, number of people in the mall, store traffic and other real-time information. Users can perceive in real time whether restaurants need to queue up and which products are on sale in trendy stores through their mobile phones. At the same time, combined with user portraits, AR indoor navigation will bring users a personalized offline scene experience. In terms of AR presentation, indoor navigation devices will also be expanded from mobile phones to AR glasses, AR headsets and other hardware to solve the dizziness and eye fatigue caused by mobile phones displaying AR maps for users.

It is worth mentioning that the report “Virtual (Augmented) Reality White Paper 2021” of the China Academy of Information and Communications Technology stated that AR relying on Inside-out technology is becoming more mature, and tracking and positioning will present integrated vision cameras, IMU inertial devices, depth cameras, event cameras, etc. The development trend of multi-sensor fusion. AR indoor navigation will develop well with the joint participation of the industry and academia.

Conclusion: AR indoor navigationWill become a new trend in the development of the industry

In terms of the manifestation of maps, AR technology has unparalleled advantages in the integration of people, maps, and the environment. Therefore, when Google launches AR indoor navigation, to a certain extent, it may set off a new trend in the development of AR indoor navigation at home and abroad.

It can be seen from the layout of big map manufacturers such as Baidu, AutoNavi, and Sogou that Baidu is one step ahead, launching AR indoor navigation functions in some shopping malls in Beijing, Shanghai, Guizhou, Langfang and other places, and will continue to make efforts in this field in the future. . Gaode Maps followed closely, and has upgraded the AR walking navigation function this year, and may soon enter the exploration of indoor scenes.

In the current industrial Internet era, AR indoor navigation will, with the support of AI and IoT technologies, activate the space utilization rate of large indoor scenes, broaden industry boundaries, and bring more possibilities to many smart industries. We look forward to the full coverage of all indoor public scenes in the world by AR navigation in the future.

On the market today, there are many sunscreen products, from domestic to foreign: Japan, Korea, China … with different indicators. It is the diversity of origin, origin, composition (used for dry skin, normal skin, combination skin) … that makes it difficult for consumers to choose suitable sunscreen products.

Moreover, in addition to sunscreen products with clear origins, many small shops, markets, websites … sell low-quality sunscreen products but imitate the prestige “brand”, popular.

Import sunscreen products

In recent days, the weather in the North is more sunny, peaking more than 40 degrees Celsius, consumer demand for sun protection products such as sunscreen, gloves, glasses, masks, especially anti-sun sunshine increased. This is also the time for low-quality sunscreen products to hit the market.

Walking around the market for students in Cau Giay (Hanoi), it is not difficult to see the areas selling cosmetics of unknown origin and labels. Remarkably, most products sold on the market are not preserved under the necessary conditions, away from direct sunlight.

Sunscreen is also sold on a variety of websites with different prices.

According to the survey, the prices of sun protection products in these markets are quite cheap, ranging from 70-100,000 VND / bottle, lower than in stores specializing in selling cosmetics from 50 – 100,000 VND / product. At first glance, the cosmetic products on the market have the same design, design, and design as genuine products, helping consumers’ eyes. Even for those with low incomes, this will be a popular product, suitable for money.

Sunscreen – the indomitable object on a hot summer day

As one of the indispensable products on a summer day, sunscreen helps people protect the skin, avoiding the effects of ultraviolet (UV) rays in the sun. Ultraviolet rays are divided into 3 types, UVA, UVB, and UVC rays. In which, UVA, UVB rays can pass through ozone layer and harm human health; UVC rays are blocked by the ozone layer, unable to penetrate the ground. Therefore, when going outdoors, our skin will be affected by UVA and UVB rays, which darken the skin, damage the skin, accelerate the aging process and increase the risk of skin cancer.

Sunscreen helps people protect the skin from the effects of ultraviolet (UV) rays in the sun.

To protect the skin from the effects of UV rays, consumers who choose sun protection products, including sunscreens, should pay attention to choosing a cream with a higher SPF number, which protects the skin from UV rays. higher. For example, SPF 2, skin protection ability is 50%; SPF 15, skin protection ability is 94%; SPF number is 100, the ability to protect the skin is 99%. However, consumers should not choose products with the SPF number too high, as it can cause skin irritation. Therefore, consumers only need to choose at 30, 50 for the best.

Besides, when buying a sunscreen, consumers also pay attention to the PA index (denoted PA ++, +++…) on the sunscreen. The more + sign, the better the resistance to UV rays.

However, consumers also note, it is possible that the sunscreen is suitable for one person, but irritates the skin for another. So, consider before choosing this skin protection product.

Experts warn against the harmful effects of sunscreen if used in the wrong way

Recently, the US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection. Two safe and effective ingredients in sunscreen are zinc oxide, titanium dioxide. Meanwhile, the ingredients aminobenzoic acid (PABA) and trolamine salicylate have been warned by the FDA to be unsafe.

FDA also requires manufacturers to demonstrate the safety of 12 sunscreen ingredients: cinoxate, dioxybenzone, oblulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone. Therefore, consumers need to pay close attention to the ingredients on the product label when choosing sunscreen. Safe sunscreens approved by the FDA include sprays, oils, lotions, creams, gels, avocados, glues, ointments, and waxes. The agency says more information is needed before drawing a conclusion with its powdery sunscreen.

The US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection.

To prevent skin cancer, Associate Professor, Dr. William W. Huang, Wake Forest School of Medicine, recommends applying sunscreen about 30 minutes before going out in the sun and reapplying at least every two hours. Facial skin is a sensitive, vulnerable place to ultraviolet rays leading to skin cancer, so priority is given to applying cream on the face.

Ohio-based dermatologist Amy Kassouf also noted that sunscreen should be applied to small areas of skin like the eyelids, lips, and ears. Most lip cosmetics do not contain SPF. The skin on the edges of clothing is also often sunburned, so more sunscreen should be applied, according to dermatologist Jennifer Stein in New York. People with sensitive skin should use sunscreens containing zinc oxide and titanium dioxide in place of the chemical sunscreen ingredient.

According to chemist and founder of the beauty website The Beauty Brain – Perry Romanowski, expired sunscreens will no longer be able to protect your delicate skin. At this time, sunscreen, whether physical or chemical, has no longer reached the SPF level as advertised. Meanwhile, chemical sunscreens with ingredients containing oxybenzone, avobenzone and homosalate can oxidize and become less effective. Physical sunscreens contain zinc oxide or titanium dioxide, although there is no oxidation, they still lose the quality and effectiveness of sun protection. Simply put: while the sunscreen ingredients are active, they may not be able to function properly in skin protection.

Also sharing about the harmful effects of sunscreen, Dr. Erin Gilbert said that when you open the bottle of sunscreen with dirty hands, or open too many times can cause bacteria to enter the product. Decreases the quality of the cream and causes acne breakouts when used.

Dr. Gilbert recommends that if you leave sunscreen in a hot place such as in a car, swimming pool or in a bag, it will expire more quickly due to high temperature environments. In this case, you should replace it every few months to ensure that the sunscreen will always work effectively.
