Design Of Projection Super Multi View Light Field 3D Display System And Optimization Of Transparent Film Materials

With the rapid development of display technology,the traditional 2D display method cannot meet the needs of its audience anymore.3D spatial information based on 3D visual cues has gathered wide attention because it can give the viewer an immersive visual perception.However,the existing mature 3D display technology is based on the stereo vision technology based on the binocular parallax.The lack of single eye depth leads to some problems,especially the visual fatigue caused by focusing convergence conflict,which is the technical bottle neck of further development of 3D display technology.Aiming at the problem of visual fatigue caused by accommodation-convergence conflic,this paper analyzes the visual mechanism of three-dimensional perception of human eyes from physiological and psychological aspects.On the basis of the fourdimensional light field function,the 3D display theory of super multi view optical field is proposed.On the basis of this theory,we successfully design and implement a projective super-multi-view optical field 3D display system with nonaccommodation-convergence conflic.Finally,the system is optimized and verified by the principles.In the theory,based on the all-optical four-dimensional light field function,the theory of super-multi-view light field display is proposed.In the system construction: Based on the 3D display theory of super multi-view optical field,the construction of 3D display system of projection optical field has been successfully completedThe algorithm of projection type ultra multi view 3D display system is successfully designed.The asynchronous FIFO is designed to read out the frequency of the visual frequency of the DDR internal and video display output.In the process,DDR3 arbitration is designed to solve the problem of multichannel request priority processing.In view of the possibility of losing frames caused by the unsynchronization between the light valve and the video,the image splicing is put forward.In the system optimization,the optimal parameters of the view camera are 35 degrees,the focal distance is 57 mm,and the depth of the screen can be 1200 mm when the shooting depth is 2000mm;the image crosstalk distortion is corrected and the effect of crosstalk is weakened;the system parallax uniformity analysis draws closer to the human eye when the horizontal arrangement of the light valve is used.In the experimental verification,the platform is verified by the single eye movement parallax and the continuous defocus fuzzy experiment,and the smooth moving parallax is observed.Through CCD,the platform can be naturally focused on any depth scene,which shows that the focus convergence conflict is solved,and the healthy and comfortable 3D view is realized.Finally,the liquid crystal modulating components of the key devices in the display system are enhanced to improve the transparent performance of the liquid crystal,so as to achieve a more comfortable viewing effect.
