Time division method
Time division method is an application promoted by NVIDIA now, which needs the cooperation of display and 3D glasses to achieve 3D stereoscopic effect. The stereoscopic glasses used in time-sharing method have the most complicated structure and the highest cost. Both lenses are electrically controlled and can be switched according to the output of the display. The switching between light transmission and non-light transmission of the lens makes the human eye only see the corresponding picture (in the light transmission state), and the stereoscopic imaging effect can be achieved when the eyes see different pictures.
Grating type
In order to welcome the 2008 Olympic Games, the received TV programs can be stereoscopic. Now our country has made raster stereoscopic TV, but raster stereoscopic TV also has some shortcomings, that is, the definition is worse than other stereoscopic TVs, and the definition is only slightly higher on very large TVs, but in this way, the price goes up. However, this shortcoming is difficult to overcome no matter what grating does, except for technical progress.
All-true form
The only successful stereoscopic TV technology in the world today, invented by German Thomas Houhenlake, is compatible with the original TV equipment in the world. From the TV production and broadcasting system to people's TV sets, there is no need to increase any equipment and investment, just add special devices to the camera when shooting stereoscopic programs. When watching the program, the audience only needs to wear a pair of special stereoscopic glasses. Glasses are low in cost and have no side effects on eyes after being appraised by the national health department. If you watch ordinary TV without glasses, there are few such programs at present, and this technology is facing elimination. Now some digital TV programs have such programs again. Disadvantages: there are few program sources and the stereo effect is not very good.
Screen observation mirror
Previously, it was dedicated to looking at the picture pairs taken by stereo cameras, and the picture pairs were generally presented left and right. Now this kind of viewing mirror can also watch left and right stereoscopic movies. Disadvantages: when watching an image or movie, it can only be half the size of the screen at most; Advantages: Very clear.
Holographic type
This kind has not been popularized yet. It's stereoscopic from all angles, without stereoscopic glasses. The price is staggering, and it is only displayed in the science and technology museum.
Ordinary computer
Ordinary computers can see red, blue, parallel, cross and other 3D stereoscopic images, and only need simple viewing equipment or naked eyes. There is nothing special about images, just ordinary pictures and special picture placement. More complicated naked eyes, polarization and time sharing can also be realized on ordinary computers, but more expensive display equipment is also needed. The naked eye needs a display screen that can be displayed with the naked eye; Polarization and time sharing can also be realized through display screen and special stereo glasses. The best way is to use 3Dvision stereoscope, but you also need a graphics card made by NVIDIA (3Dvision is a product of NVIDIA). Of course, a 120HZ display screen is absolutely indispensable. From a related publicity of Samsung, the bigger the screen, the better (and of course more expensive). If the components of the "ordinary" computer are not included in the calculation of the display, of course, you can also choose IZ3D plus two projectors and polarizers and other related software for polarization projection and playback. To achieve the effect of Avatar in the cinema, ordinary users can't achieve it at present. Generally speaking, the development of 3D on computers is not the fastest at present, but it is definitely the most promising. Perhaps there are not many devices that allow people to enjoy 3D completely on the computer as they do in the cinema today. In the near future, you will be immersed in it because of the cheapness and diversity of computer 3D devices.
