摘要

针对当前自由立体3D显示器的最佳观看距离固定和无法灵活调的等问题，本文在Unity3D平台上采用Cg语言编程，提出了可变视点数立体图像合成算法。该算法根据最佳观看距离与视点数之间的关系，调整光栅截距对应的像素点，实现了通过灵活改变视点数来改变自由立体3D显示的最佳观看距离。实验结果表明，通过此算法合成的立体图像可以调整显示的最佳观看距离，并且实验测得的视点数与计算所得的视点数误差较小。图像串扰较低、合成效率高，使观看者能在不同距离都能舒适观看立体图像。

Abstract

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.
