* Naked Eye 3D Display Technology What is naked eye 3D display technology As a new type of image-display technology, the naked eye stereoscopic display enables viewers to have a unprecedentedly vivid visual experience without wearing 3D glasses. Development of the 3D display technology Black-white display Visual-aid 3D display Naked eye 3D display Color display 3D Glasses 3D Helmet The basic theory of 3D display technology Humans see objects and have a stereoscopic impression, because that when our eyes look at a same space object , actually, the image of our left eye capture and right eye is slightly different for a certain distance between the eyes. After the two images (parallax image) are synthesized in the brain , we can grasp object three-dimensional contour. Data flow of 3D capturing and displaying 1. Multi-view capturing 2. Background subtraction and synthesis 3. Obtain multi-view interlacing images 4. Display left/right images 3D image capturing 3D camera The 3D camera is equipped with two lenses,which be used to simulate the human eyes to capture left and right parallax image. 3D image capturing this picture show that the hardware circuit board of 3D display system, which mainly consist of parallax image capturing section, digital data processing and system control section, and 3D display screen. digital data processing and system control section left lens right lens 3D display screen synthesise of left and right parallax image synthesize Left and right parallax image Synthesized image *
