同时，本文找到并且理论证明了两摄像机平行放置时，左右图像中区域对角线的对应关系。
The corresponding relationship between area's diagonals of right-and-left images is proved when two cameras are parallel.
这种方法在对角线方向上的频率响应特性较好，而在水平和垂直方向上对基带外的垂直频谱衰减不够，导致放大图像中的方块效应。
But there is Mosaic impact in the enlarged picture because this method can't adequately attenuate the vertical frequency off the Base Band in the horizontal and vertical direction.
该方法将两幅沿对角线方向错位拍摄的CCD图像迭加成一幅合成的图像。
In this method two CCD images taken staggeringly in diagonal direction are composed into an image.
