首先根据尺度不变特征变换方法从图像中提取关键点作为特征点，然后进行左右双目图像的特征点匹配和视差的恢复。

Then use these feature points for binocular matching thus getting distance information of the scene by the calculation of differences between match points in two images.

针对双镜立体照相技术重构立体图像画质模糊、图像受损、清晰度下降的问题，采用光开关对镜头光路左右对称分割，获得视差图像。

For solving the problem of ghost image recurred on 3DTV, the light-path of lens is symmetrically divided by optical switch to obtain parallax image.
