Product application has been so mature! Acer's naked-eye 3D technology experience greatly exceeds expectations

I was fortunate to receive an invitation from Acer. I participated in the Acer Glasses-free 3D series city tour in Beijing. Before I went, my understanding of the glasses-free 3D technology was still at the stage of the glasses-free 3D large screen. In my impression, naked-eye 3D is more of a follow-up product after the rise of 3D technology in theaters, and it is more gimmicky than practical. But after experiencing Acer's glasses-free 3D technology this time, I have a new understanding of glasses-free 3D. Let's start with the conclusion: it exceeded expectations too much! Acer's naked-eye 3D technology and product completion and availability are very high, and I personally think that the market potential is huge. 01 "You even want to grab it with your hands" provided 4 experience machines, including 1 notebook, model of ConceptD 7 SpatialLabs Super Sensing Space Glasses-free 3D version, and 3 portable monitors, model of SpatialLabs View/View Pro Super Sensing Space Naked eye 3D version series. The naked-eye 3D experience of the two is almost the same, and the actual experience mentioned later will not be distinguished. First of all, the effect of Acer's naked eye 3D is very realistic, as if the world in the screen is suspended on the screen, especially the picture with obvious depth, the three-dimensional effect is very strong. The friends who experienced the scene even stretched out their hands to grab the pictures they saw, but the results were obvious and they were empty. Secondly, even if you move back and forth, left and right when watching, of course, the moving distance should not be too large, the 3D effect you see is still the same as before, and there will be no ghosting or ghosting. The viewing effect of Acer's glasses-free 3D is very close to AR glasses, which is better than the effect of 3D theater (or maybe I haven't seen a good 3D movie), but it does not require any hardware equipment. 02 How exactly does it do it? To achieve such a brilliant naked-eye 3D effect, there is a complex set of algorithms and hardware behind it. This part of the algorithm is skipped directly. I don't know much about it, and the experts in Acer only briefly mentioned it. Let's focus on some of the technologies mentioned on the spot. It should be noted that the following description will contain personal understanding, and some of the contents may contain errors. Before that, briefly think about how we have stereoscopic vision. When we look at an object, the left and right eyes can obtain two images, and the two images have parallax, and then the brain compares the information of the two images to obtain information such as distance and bump. So if you want to "fake" the 3D effect, you need to provide a suitable parallax image according to the distance between the human eye and the screen, which can be divided into 5 points. First, the distance between the human eye and the screen needs to be known, and this distance is not fixed and needs to be tracked; second, the depth of field information of each part in the image is required; third, an algorithm is required to simulate the depth of field information into a parallax image; third Fourth, a special screen that can display parallax images is required; fifth, the whole process requires a lot of calculation, and must have good computing power support. Due to parallax images, cameras and mobile phones cannot capture naked-eye 3D effects. Let's see how Acer does naked-eye 3D. There are two image sensors on the top of the screen of SpatialLabs View Pro super-sensing space naked-eye 3D version (a naked-eye 3D portable display for on-site experience), which can identify and track the user's head and eyes, so as to provide real-time feedback of the user's position information , which solves the problem of the distance between the human eye and the screen. Of course, since the two image sensors can only track a person's face and eyes, the Acer naked-eye 3D is currently only suitable for one person. 3D content includes 3D images and 3D models, the former itself provides two images with parallax, and the latter contains rich depth of field information. What to do with 2D content? Acer's naked-eye 3D approach is to use self-developed AI algorithm to convert 2D content into 3D content, which is equivalent to automatically calculating the depth of field information in the image through the algorithm. The algorithm for simulating parallax images is also not much to say, which should be the core of the system. In addition, the Acer naked-eye 3D screen is specially made, and the surface is covered with a layer of optical lenses. Personally guess that the original image + the image refracted by the optical lens are superimposed together, which is equivalent to the images obtained by each of the two eyes. The refractive index of the optical lens can be controlled to simulate the images obtained by the eye at different distances. Finally, among the products demonstrated on site, the configuration of the host connected to the three portable monitors is unknown. The independent display of the ConceptD 7 SpatialLabs super-sensing space naked-eye 3D version is Intel i7+RTX 3080. It seems that the requirements for computing power are not low. 03 Where is its value? Personally, I think that the biggest advantage of Acer Glasses-free 3D is not only the excellent naked-eye 3D effect, but also that it does not require any hardware equipment. It reduces the user's learning and operating costs to a very low level, so low that you only need to be in front of the screen. This excellent ease of use determines that it is more acceptable in the industry. It is foreseeable that the demand for such technologies in all walks of life will increase in the future. Acer naked eye 3D achieves what you see is what you get, which can significantly improve efficiency. And companies are very willing to pay for increased efficiency. Acer Glasses-free 3D is suitable for industries that use images as an important output, such as the field of 3D design, medical field, retail exhibition field, and education field. Personally, I think that the earliest widely used field of Acer Glasses-free 3D is very likely to be education and training, which is also the first field where consumers can come into contact with Acer Glasses-free 3D. The education and training market has always had an urgent need for innovative educational tools. Acer Glasses-free 3D has two obvious benefits, one is better training results, and the other is the ability to attract more potential customers. Moreover, the education and training market is large enough, and the economic benefits brought by Acer naked-eye 3D can be reflected more quickly. It was when I saw its possibilities in the education and training market that I thought it had huge market potential. A curious friend inquired about the price of the ConceptD 7 SpatialLabs super-sensing space naked-eye 3D version. When I heard that it exceeded 50,000 (not the final retail price), my heart trembled. The technology is very good. When it is currently in the stage of technological innovation, the cost is still relatively high, and it is suitable for commercial use, but it is still some time before it can fly into the homes of ordinary people. However, in my personal judgment, the independent naked-eye 3D display is the protagonist of this year's new product. The price should be set at around 10,000 yuan. Let's wait and see. (8002984)
