摘要

立体视觉中，虚拟的中央眼是立体空间定向的依据。中央眼存在个体差异，然而现有虚拟现实技术在立体影像呈现过程中尚未考虑到中央眼的个体差异。模拟的射击实验结果表明，人眼视觉系统对立体空间中，物体之间相对方向的判断极其敏感，实际中央眼位置与理想情况之间的微小偏移会带来显著性的感知差异。虚拟现实技术模拟真实场景的拟真性和交互性可以通过考虑个体中央眼位置的方式进行提升。本文通过对人眼双目定向理论的分析，提出了基于中央眼位置的虚拟空间重构方法，采用对立体相机系统反方向平移的方法补偿由于中央眼偏移带来的偏差。所提出的方法有望为虚拟现实技术拟真性和交互性的提升提供理论依据。

Abstract

In the binocular vision

the virtual cyclopean eye is the reference center for stereo space orientation. There is difference between the cyclopean eye locations of different users

which is not considered in the virtual reality system when presenting the stereo images. The results of shooting simulation experiment showed that the human vision system is sensitive to the relative visual direction offset

and the slight difference between ideal and actual cyclopean eye locations will lead to significant perception difference. The vividness and interactivity of virtual reality system can be improved through considering the exact cyclopean eye location of the user. This paper analyzed the binocular visual direction computation theory

and proposed a virtual space reconstruction method based on the actual cyclopean eye location of specific user. The deviation brought by the cyclopean eye location shift is compensated by the opposite direction shift of the stereo camera system. The proposed method may provide theoretical reference for improving the vividness and interactivity of the virtual reality system.
