许多场合需要精确观看与真实景物相似的立体影像,立体拍摄和再现系统应无畸变。提出的再现立体影像垂轴放大率概念,其具有与拍摄相机的垂轴放大率互补的特性。由此根据再现立体像的垂轴放大率与轴向放大率应相等这一消畸变的基本要求推导了立体拍摄和再现系统的消畸变条件。提出了消畸变系统的设计方法和设计流程,计算并通过验算证明了设计方法的正确性。该方法设计流程简单合理,设计的立体拍摄和再现系统,在正面观看时可在很大的纵深范围内得到消畸变立体影像。

Stereoscopic images need to be observed accurately in many applications,where image distortions are not allowed in the stereoscopic camera and display systems. The concept of vertically axial magnification of the reproduction stereo image is presented,which may have complementary characteristics to the paraxial magnification of the camera. Therefore,according to the basic requirement that the paraxial magnification of reproduction image should be equal to the axial magnification,the eliminating distortions conditions of camera and display system are derived. A design method and flow program for the stereoscopic camera and display systems is proposed. Design examples are given and the design method is proved correct with checking computations. The design method and flow program are exact and simple. Using the design method,stereo image without distortions can be in a much large depth range for front viewing.
