The “L-shaped” screens that have recently appeared on the Internet have attracted a lot of attention, and such displays frequently appear in major cities, attracting attention with their shocking and realistic picture effects. Most of the naked eye 3D screens in shopping malls are corner screens to present users with realistic, three-dimensional images. So do you know how such an effect is made? What are the advantages of the application of naked eye 3D LED screen? And what black technology is hidden behind it?
Naked eye 3D effect production.
To be able to achieve such a stereoscopic video, two killer features are used here: borders and artificially distorted images.
1、Borders.
By letting the subject of the picture to the outside of the frame, so that people will instinctively think that the picture in the screen is originally fake, and whether the TV or computer will have a border, so the picture should be within the border, we need to artificially paint a border, when the main picture beyond the frame, it will give people the cognitive contrast, so as to achieve the 3D stereoscopic effect.
2, artificial distortion of the picture.
Obviously the 3D big screen only has the best stereoscopic effect when viewed at a specific angle. If the viewing angle is too low, or if a normal video is played, the picture becomes imperfect.
Even when viewed at the best angle, if the picture is not artificially distorted, it will look like this. The original road is then folded up. But if a straight line is displayed on a shaped screen, we can only view it at the same height as the line. The straight line is at an angle if you observe it in any other position. This kind of naked eye 3D video generally can only be viewed at a specific angle to have a sense of three-dimensional, from other angles to see the picture is will stretch and distortion, can achieve the desired effect. We need to know the resolution and size of the big screen, what position the folding angle is in the big screen, follow up the size of the big screen to build the corresponding field volume, choose the right angle to render the scene will be rendered out of the finished film or video with post software to match the resolution size of the big screen.
Naked eye 3D application advantages.
I. Three-dimensional effects.
The use of screen shape and border effect creates the feeling of a three-dimensional scene, which can give users a visually impactful experience and also serve as a new way to promote advertising and marketing.
2. Second, the sense of technology.
The combination of culture and technology of naked eye 3D LED screen is not only a cool effect, but also the culture is output to users in a trendy way, creating a unique visual expression effect. The effect of naked-eye 3D technology is displayed, but also through the naked-eye 3D advertising screen will be a unique display of culture and art to improve the aesthetics of the public.
III. Accurate communication of information.
Visual effect is one of the display features of naked eye 3D LED screen, and the message conveying effect of which can be conveyed by the film created by naked eye 3D technology, novel and unique picture display, firmly grasp the user’s vision. Therefore, naked eye 3D advertising screen is gradually becoming one of the ways of marketing promotion. The display of naked eye 3D LED screen can not only bring users a novel and unique visual experience, but also enliven the atmosphere of the scene through a series of display methods during the display.
The strong visual effect can attract many users of the display, naked eye 3D advertising has therefore become a major secret of local attraction, novel and shocking display effect for the public to bring a strong visual impact, but also successfully let people remember the naked eye 3D this emerging technology, even if facing such high costs and application restrictions, there are still many application industries: advertising and landscape display, entertainment industry, industrial and architectural design.
Naked eye 3D production costs:
We can easily see that the picture on the big screen is distorted, and the production can only adapt to this screen. Each naked eye 3D landing will have an exclusive custom program, through scripting, modeling scene construction, and post-lighting rendering to make something abstract concrete. There is no way to view it properly with computer or TV, so the production cost is high and there are many restrictions.
1. Hardware screen and supporting accessories
Naked eye 3d screen area are hundreds of thousands of square, the display resolution are selected 4K or even 8K resolution. High refresh, high gray scale, high contrast for the characteristics of the details expressed to the fullest, to give the audience a visual impact effect.
2. Site selection and material costs
Most of the choices are in high traffic flow, high coverage, large audience and strong visual impact. Advertising rental is also a considerable expenditure, and the installation method also has a lot to do with it, for example, the price of P8 outdoor LED display is 1990 yuan per square meter.
3. Hosting and animation production costs
Compared to the scenes of simple level products, the content of the scenes in this large screen has a strong impact, and the main character has real action, such as waving, running, collision, not just drifting. There are transitions, not just single scenes, and commercial use starts at 30,000 RMB/sec (20 seconds to start).
3D naked-eye technology is still progressing towards a richer and more realistic direction. Through the continuous efforts of researchers, 3D naked eye technology has a better development prospect, in the future there will be more channels to use this technology, but also with more technology integration, forming a broader application areas. 3D naked eye technology, the future can be expected!
