										<content:encoded><![CDATA[<p><strong>Sitting in the movie theater, the car rushing on the screen felt like it was about to hit him head-on. On the movie screen, the battleship shuttles in space, as if he is in a strange outer space, exploring the boundless universe. The realistic effect of the 3D movie allows the viewer to escape the identity of the masses who &#8220;watch the fire from the other side&#8221; and experience the immersive experience, and feel that they have entered the picture.</strong></p>
<p><span id="more-24067"></span> If the 3D movie led by &#8220;Avatar&#8221; in 2009 presses the start button for the stereoscopic experience, then the development of AI stereoscopic display technology will fully activate people&#8217;s more comprehensive stereoscopic vision needs. Throw away the 3D glasses, get rid of all kinds of auxiliary equipment, and see that 3D with the naked eye is shining from dreams into reality. In fact, when it comes to naked-eye 3D, I believe everyone is familiar with it, but when it comes to the upgrade technology of naked-eye 3D-the artificial intelligence stereo display technology of Guangdong Future Technology, you may not be very familiar with it.</p>
<p>Guangdong Future Technology Co., Ltd. was established in 2015. It is a national high-tech enterprise and the world&#8217;s leading provider of complete solutions for artificial intelligence stereo display technology. The company is located in the world-renowned &#8220;Guangdong Street Office&#8221; central park. Since its establishment in 2015, the company has been committed to the research and development of a new generation of artificial intelligence 3D display technology. After more than 6 years of development, it has successfully developed a leading artificial intelligence 3D display Technology, 3D stereo camera, 3D scanning, spatial position recognition, spatial stereo imaging and other innovative technologies, forming a complete set of industrialized solutions from 3D data collection to display, with more than 60 industry-leading independent core technologies and intellectual property rights .</p>

<p>Eight years ago, the international e-commerce giant Amazon said it would make a naked-eye 3D mobile phone. As an internationally well-known Internet company and e-commerce giant, why should a 3D mobile phone be made? The significance of 3D mobile phones is not in the hardware itself, but in subverting the traditional Internet shopping model. The traditional Internet shopping model is the O2O model, which refers to offline experience and online purchase. For example, we go to a physical store to try on and experience shoes, and then place an order online. In the future, we may use 3D stereo display technology to subvert this model. This is called the O1 model, which can solve the offline experience through online. Just like the 3D scanning on our booth, the human body modeling data is obtained by scanning, and then we choose 3D shopping on the mobile phone, there will be two particularly good effects: First, you can actually see yourself wearing this dress How about the three-dimensional effect of the body; Second, the data can tell us more scientifically that this piece of clothing is not suitable for you, such as your waist circumference, shoulder width, and sleeve length. Use data to verify.</p>
<p>The core feature of the Internet is to exceed user expectations and exceed user experience. These experiences achieved by 3D stereo technology can be better than offline. Of course, 3D stereoscopic display technology has a wide range of applications. For example, the application of overpass navigation is definitely more advantageous than planar navigation, and the real-time decoration effect presented by the three-dimensional modeling of the room has more advantages than the two-dimensional decoration effect. At the same time, the stereo display can also be applied to geography teaching.</p>

<p>From black and white to color is the trajectory of the development of visual presentation in the past, and from flat to three-dimensional is also the inevitable trend of future development. Nowadays, most movies are in 3D, and most games are also 3D. For example, the well-known &#8220;Honor of Kings&#8221; and &#8220;PlayerUnknown&#8217;s Battlegrounds&#8221; are all 3D.</p>
<p>3D content has also become the mainstream, but everyone needs to wear 3D glasses to watch 3D content, which has major limitations and dependence on viewing auxiliary equipment. Therefore, how to remove the 3D glasses and be able to directly watch 3D content on the existing display terminal has become a user&#8217;s demand. Naked-eye 3D technology came into being under this background. It allows all display terminals to achieve stereoscopic display functions without the need to wear 3D glasses and viewing aids.</p>
<p><img decoding="async" src="https://p4.itc.cn/q_70/images03/20210615/a69557b19db4427fa1a1a3915a1ad026.png"></p>

<p>Huawei’s rotating chairman Guo Ping mentioned naked-eye 3D at the Huawei Global Analyst Conference on May 18, 2020. He said that if naked-eye 3D technology can be realized, it will bring a revolutionary improvement to the industry and will be widely used. It is used in life, entertainment, medical education and other fields. At the same time, it is possible to create a new industrial space of hundreds of billions, and drive the entire industry to achieve leapfrog development.</p>
<p>In the technical field of stereoscopic display, naked-eye 3D is an older concept, and there is a problem of viewing angle. Users need to be in a specific position to see the 3D stereoscopic effect, which has certain limitations. Guangdong Future Technology has broken through technical barriers and solved technical problems on the basis of naked-eye 3D. Their AI stereoscopic display technology combines artificial intelligence with the fifth-generation Fermat grating technology, which solves the problems of viewing angle and vertigo, turning the traditional naked-eye 3D into a true artificial intelligence stereoscopic display.</p>
<p>Future Technology has the world&#8217;s leading 3D optical/display design capabilities and advanced module production technology and core technology patents. Through the underlying software algorithm, combined with high-end biological imaging technology, the system is optimized in depth, using proactive automatic tracking to lock the eye position, and automatically adjust the image interleaving sequence according to the eyeball position to ensure high-quality viewing effects. Unique 3D game engine, supports Unity3D, OpenGLES, 3D automatic rendering engine, active contrast compensation algorithm, and supports mainstream games such as Honor of Kings to run in 3D state.</p>
<p>Artificial intelligence three-dimensional display technology has very rich application prospects. For example, after we scan the body with a mobile phone, the modeling data of the human body is automatically generated. When we click on a piece of clothing, the modeling data of the human body will be modeled on the clothing. Data is matched to solve the problem of matching degree between human body and clothing. Hailan House’s advertisement &#8220;Men visit Hailan House twice a year&#8221;, we may not need to visit once in the future. Through modeling and data matching, we can complete the trial fitting session online. This subverts the traditional Internet O2O shopping model (offline experience, online purchase) and turns O2O into O1 (complete offline experience through online), which will bring us great convenience.</p>

<p>Artificial intelligence stereoscopic display technology is a very innovative technology that can be applied to all display terminals such as mobile phones, tablet computers, desktop computers, notebook computers, LCD monitors, televisions, and advertising screens. The product research and development layout of Guangdong Future Technology Co., Ltd. has been applied to many products. Currently, products such as tablets and mobile phones equipped with AI stereo display technology have been launched. In addition, 3D stereo live broadcast equipment and 3D stereo cameras are also ready to be launched.</p>

										<content:encoded><![CDATA[<p><strong>If you want to hear &#8216;splendid&#8217; sounds from a stereo recording such as detailed information about the original recording location, a sense of spatial openness, depth and breadth of the image, position and the focus of the instrument&#8230; you not only need good hi-end equipment, but you also have to set up the system in the listening room in the most careful and reasonable way.</strong><br />
<span id="more-21673"></span> <img decoding="async" loading="lazy" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/b0a2b73ba4794d271468.jpg" width="625" height="468"> </p>
<p> <strong> Create a clean path from the speaker to the listener&#8217;s ear</strong> The perception of stereo sound depends on subtlety and in particular on the presence of live sound as well as the immediate feedback that follows. Incoming sounds play a general role in what you&#8217;re hearing, but they&#8217;re not as important in stereo as the &#8220;first-in&#8221; effect (the latter is considered unimportant by the ear/brain&#8217;s decision). spatial and positional information). Now do you understand what we mean by “clean road”? You don&#8217;t need anything on the floor or anything else close to the path from the speakers to where you sit. The floor and ceiling of the listening room should be flat and smooth because high frequency reflections will be minimized. If the ceiling is not very high, it is better if it is made of a soft and smooth object. The problem here is that rough materials, such as appliances and furniture, will cause the sound to be distributed unevenly. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/35823c1b2f59c6079f48.jpg" width="625" height="452"> This is one reason why the stereo effect is blurred and the ideal performance cannot be obtained. A friend in the test room asked me to close my eyes to test the change of stereo sound when there is an obstacle in front. When the music plays, I feel the change quite clearly, the stereo comes out in parts, becomes distracting and the sense of space is seriously affected. Then my friend told me to open my eyes. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/3c2f33b620f4c9aa90e5.jpg" width="625" height="416"> What surprised me the most was that he just silently placed the CD cases on the floor symmetrically between the speakers and a few in front of us. This is obviously not a huge physical change, but it does sabotage stereo performance a lot. So what if you put a coffee table or put a few remotes on it symmetrically with two speakers and in front of a music chair? Maybe it will be convenient for you to enjoy the melodious music while sipping a cup of coffee, but you will certainly not be able to fully feel the stereo performance. <strong> Get rid of objects next to you, use a chair with a low back</strong> <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/32d63c4f2f0dc6539f1c.jpg" width="625" height="365"> <em> Although using a chair with a low backrest, the arrangement of the chair as shown in the picture makes it impossible for both listeners to experience the stereo effect.</em> Hard objects near your ears along a straight line are seen to greatly affect when you listen to music. It&#8217;s best to sit in a chair with a very low back, as that will put nothing near your ears. If your back doesn&#8217;t adapt to this, you should at least use a chair that doesn&#8217;t go over your head and make sure it&#8217;s soft. Hard leather sofas become weak points because they reflect high frequencies. If you are sitting alone, cover the area behind and near your head with a cloth curtain. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/c852c5cbd6893fd76698.jpg" width="625" height="416"> Because otherwise, a lot of high frequencies will be scattered before reaching you, or in other words, the back wall of the listening room should design sound-absorbing materials or accessories. But using a low chair is still best. Try it! You will be surprised how much better your system will sound. <strong> Symmetry rule</strong> <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/a31eaf87bcc5559b0cd4.jpg" width="625" height="469"> Stereo sound is based on symmetry between two channels. For the latter, where people are exposed to large amounts of treble diffusivity, the role of symmetry is diminished. But for anything that comes first with the sound of low frequencies, the role of symmetry is indispensable. In the old days, when many audio players didn&#8217;t understand how stereo really worked, and especially didn&#8217;t fully appreciate the importance of the intrinsic tonal time difference, many would try to make adjustments. difference between the two channels by electronic means, i.e. adjust the equalizer and use a separate equalizer for the channels. The result was, of course, a disaster, because analog equalizers and EQs couldn&#8217;t deal with asymmetric timing effectively. When that happens, the actual digital signal processing (DSP) may be full of detail, but the problem lies in the accuracy. So it&#8217;s better to make the whole system as symmetrical as possible from the start. As always, the tuning DSP room works best when there is a lower frequency response peak and sag and is less demanding for correction (the one exception is the very wide, very useful bass correction. useful in practice). Part of the task of symmetry is on you, which is to keep the two speakers evenly spaced. In general, everyone does this, but they don&#8217;t do it fully and carefully. Let&#8217;s take a quick look at the numbers. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/0b4718de0b9ce2c2bb8d.jpg" width="625" height="346"> People can hear a time difference between the two ears of about 1/100,000 of a second. But let&#8217;s stay conservative and give it only 1/50,000th of a second. How far will the sound go in 1/50,000th of a second? Well, a millisecond (1/1000 of a second) is about a footstep. So 1/50,000 is about 12/50,000 feet, which is about a quarter of an inch. So if you want stereo speakers, you need to get them within a quarter of an inch. Time is a measure! Mark the spot and keep it there. <strong> Sit near your speakers loa</strong> There will always be some sound coming soon that you really don&#8217;t expect. So try to make them symmetric and have smaller amplitudes, but there are bound to be some limits. The way to minimize their effects is to make the live sound appear as early as possible. Sitting close to the speaker is how you do this. Of course, you also can&#8217;t sit too close, because most speakers depend on a certain distance for the accuracy of the drivers. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/916783fe90bc79e220ad.jpg" width="625" height="416"> And to some extent, you need some distance to avoid hearing the microscopic vibrations because that can make the speaker more visible than the music source. But you&#8217;ll get the best stereo sound if you sit reasonably close to the points. Many people sit too far and to the far end of the room due to the fact that the music room is too long. Sitting closer to the speaker changes the direct sound reflection ratio. You should also sit away from the wall behind your back, and the speakers should also be away from the wall behind them (unless they are designed to be wall-mounted), because positioning the speakers and listeners too close to the wall will cause discomfort. benefit the sound of a stereo system. <strong> Need a soft room</strong> Many recordings (CDs or LPs) are made with the expectation that some room sound will be added as the music plays. A few other recordings were made with the expectation that they would not be echoes when heard. But all those effects don&#8217;t stand a chance if your listening room is too small. In my opinion, the best stereo sound should be presented in an RFZ (no-reflection room) room. In such a room, early incoming direct sound will be in moderation, and sound reflection will soon be absorbed. After you hear the live sound, the listening room will appear to be assisted by sound diffusion, where discrete sound reflections are not evidence, or the sound will arrive too late after the initial sound. arrived. As a result, live sound is heard more clearly, without being confused. While building an actual RFZ room is quite a challenge, you can handle it well by making a &#8220;soft&#8221; listening room, which will especially help the treble get the most out of it. In addition, a soft acoustic environment will also result in more harmonious notes. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/04f3156a0628ef76b639.jpg" width="625" height="343"> If your music room has a large picture, use fabric drapes to cover it while listening to music. In particular, the wall of the music room made of glass would be a disaster. A few years ago, a friend brought to my apartment a system to edit rooms. Then this apartment had a spectacular view, located on a high ground and had a long wall of nothing but glass and steel support. But when it comes to music, it&#8217;s clear this room can&#8217;t get the most out of it unless I add some curtains. <strong> Sit still and close your eyes</strong> <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/1e7d0ee41da6f4f8adb7.jpg" width="625" height="416"> Part of that symmetry is placing the music chair in the right position. Unless you move the seat straight forward or backward, you will end up in an asymmetrical position! But there is another way of sitting that is really subtle and more important than the effect. This is a complex topic so I can only give an overview. As the brain builds perception from raw data during processing, what we &#8220;see&#8221; or &#8220;hear&#8221; is not the same as light in our eyes or sound in our ears. Because it&#8217;s just a mental construct. This particular mental construct often includes the following surprising things: it will use many signals, but if one signal is lost, the brain will recognize it as lacking and simply reprogram itself to use other signals. This may sound crazy, but there&#8217;s a simple visual experiment you can illustrate with that principle. Look at a photograph with a lot of three-dimensional (3D) material in it or at a painting with strong perspective, then you will get some impression of a three-dimensional image. But if you look at them with one eye closed and the other through a short tube that blocks the background and only allows you to see the picture, there is a surprising increase in the perception of three-dimensional images. If you&#8217;ve never tried this, you&#8217;ll have a hard time believing that your eyes can see the background around the picture of the picture (the way you usually look at a picture), and the brain will pick up some signal about the picture. that three-dimensional perspective. But the brain will also receive information that the surface of the painted or printed picture is in fact only two-dimensional. Binocular vision shows a fatter picture, and the background shows it too. So the brain is getting conflicting signals, which means it allows you to see some of the three-dimensional image, but not all of it. When you look with one eye and don&#8217;t see the background, the signal to that fatter image is blocked. Going back to the world of sound, one of the ways the brain detects the position of an object, the shape of the hearing room, of space, or in general auditory terms, is to slightly move the head and Notice the changes in the sound. People will have the feeling that they suddenly &#8220;sink into&#8221; the space of stereo sound. There are some people who choose to sit absolutely still. This will put the listener in a quiet state, and obviously very suitable for listening to music. And, to my ears, the stereo got better. <img decoding="async" loading="lazy" class="lazy-img" src="https://photo-baomoi.zadn.vn/w700_r1/2021_06_07_280_39102034/515846c15583bcdde592.jpg" width="625" height="416"> Finally, closing your eyes also eliminates cues that a person can&#8217;t hear in a concert hall or a stadium, but can hear from the speakers in your listening room. In short, sit with your eyes closed, with your head completely still, in a chair near the speakers in a &#8220;soft&#8221; room and in the correct symmetrical position with no obstructions in the line. between you and the speaker. If you do all that, I guarantee your stereo system can perform at its best. Hope you find the best stereo sound!</p>
