摘要：

提出了一种视差可控的多视点立体图像校正算法。该算法通过对多视点信息进行旋转、垂直视差调整和视差均衡的预处理操作,使得立体图像符合立体显示器的要求,并且对图像中的目标物体可根据需要显示为正视差、负视差或者零视差。通过在多视点立体显示系统上的实验可看出,该算法校正后的多视点图像在观看时立体感强,符合人眼观看的特点,并且可根据内容的需要使场景内的目标物体显示出不同的深度。

关键词: 多视点立体显示, 视差均衡, 正视差, 负视差, 零视差

Abstract:

A parallax-controlled multi-view image rectification algorithm was introduced.Through rotating,vertical parallax adjustment and parallax balance,the information of multi-view image could be rectified.The stereo image could meet the requirements of multi-view stereoscopic display.The object could be displayed with plus,minus and zero parallax.Experiments show that the rectified stereo images can be displayed on the multi-view stereoscopic display with excellent stereo perception,and the target object can be outstanding,sunken or on the screen on demand.

Key words: multi-view stereo display, parallax balance, plus parallax, minus parallax, zero parallax
