摘要
三维立体显示是虚拟现实的关键技术,它模仿人眼立体视觉将空间中的物体以三维立体方式再现出来,其中图像立体深度是重要的参数。本文计算分析了在panum融合区内影响立体图像深度的一些参数,如双眼视差、视距和瞳距等。依据这些参数对光轴平行的双目摄像机镜头间距进行调整,以拍摄出理想的视差图像。分析结果为拍摄立体图像时确定相机间距等参数提供数据参考。
Three-dimensional display is the key technology of virtual reality,which imitates human eye stereoscopic vision to reproduce objects in space in a three-dimensional,in which the image stereo depth is an important parameter.We calculated and analyzed some parameters as binocular parallax,stadia,interpupillary distance that affects the depth of stereo image in the Panum fusion region.Based on these parameters,the distance between binocular cameras with parallel optical axes is adjusted to obtain an ideal parallax image.The analysis results provides reference data for determing the spacing of the camera and so on when shooting and producing stereo image.
