立体显示中的垂轴放大率
Paraxial Magnification of Stereoscopic Display
摘要
为消除立体影像的畸变需研究拍摄再现立体影像的垂轴放大率.重新推导了立体影像拍摄再现的总垂轴放大率公式,在该公式中增加了一个观看再现放大率系数,立体影像的观看再现垂轴放大率为像距与观看距离之比.实验结果验证了理论的正确性,该公式对于进一步研究再现立体影像的消畸变具有重要作用.
Abstract
In order to eliminate distortions of stereo image,the paraxial magnification of stereoscopic camera and reproduction system need to be studied.The paraxial magnification formula was rederived and discussed.The new formula adds a coefficient to represent the paraxial magnification of observation and reproduction which is in the ratio of the image distance to the distance between the eyes and screen.The formula accords with the result of verifying experiment.It is important for further study on the distortions elimination of stereoscopic camera and display system.
