摘　　要：平行摄像机阵列移位法是一种摄像机阵列获取三维场景的视差图像的新方法.该方法在平行摄像机阵列法的基础上,将获取的视差图像进行平移处理,获得了立体显示所需的具有正、负水平视差的视差图像,且这些视差图像没有楔形失真和垂直视差.该方法集中了会聚摄像机阵列法和平行摄像机阵列法两种常规方法各自的优点并摒弃了其缺点.实验证实,所获取的视差图像在光栅式自由立体显示器上得到了三维场景的清晰逼真再现显示效果.A novel method of parallax images acquisition using parallel camera array with shift is proposed.The method uses parallel camera array to get parallax images with shift and acquires the parallax images with both positive and negative horizontal parallax.The parallax images have no vertical parallax or wedge-shaped distortion.The method integrates the advantages of the conventional methods using toed-in camera array and parallel camera array and gets rid of their disadvantages.The experiments verify that good stereo images having high sharpness present on an autostereoscopic display device and the stereo images are very similar to the real three dimensional objects.
