Variable-viewpoint stereo image synthesis algorithm based on Unity3D

For the problems of the autostereoscopic 3D display, such as the fixed and unadjustable optimal viewing distance, this paper proposes a variable-viewpoint stereo image synthesis algorithm based on the platform of Unity3D using Cg language programming. The algorithm adjusts the pixel corresponding to the pitch of lenticular lens based on the relationship between the optimal viewing distance and the number of viewpoints, which can flexibly change the optimal viewing distance of the autostereoscopic 3D display by changing the number of viewpoints flexibly. The experimental results show that the stereo image synthesized by this algorithm can adjust the optimal viewing distance, and the error between the number of viewpoints measured and the number of viewpoints calculated is not obvious. The image crosstalk is low and the synthesis efficiency is high, and it satisfies viewers to watch stereo images comfortably in different distances.
