基于单摄像头双目成像系统在计算机视觉中的应用研究

利用单个摄像头和一平面镜的舍体实现了双目成像系统的三维视觉功能，并理论证明了平面镜相对于摄像头按一定条件放置时，利用合体可以得到适于三维立体视觉的图像。在已知舍体内外部参数的情况下，由舍体所得图像进行点的三维立体恢复的理论推导。对合体的标定、内外部参数的确定也进行了理论推导。最终证明，由合体进行三维立体恢复，其实质相当于双目成像。通过实验对合体和一双目成像系统分别进行了标定，利用标定的结果进行了对点的三维立体恢复。结果表明两者精度相当。

Application of binocular vision system based on one camera in computer vision

The 3D computer vision is accomplished by a new vision system based on the combination of one camera and one mirror instead of binocular vision system. It is proved theoretically that if the mirror is placed in the certain conditions, the images that can be used to accomplish 3D stereo vision restoration is obtained from the combination. The point′s world-coordinates are calculated theoretically by use of the images, supposing the interior and exterior parameters of the combination are known. The calibration, parameters calculation and point′s 3D stereo restoration of the combination are also deduced theoretically. It is also proved that the essence of the combination′s 3D restoration is identical to the binocular vision system. Experiments are presented to contrast the performances of the two methods. The results show that the accuracies are nearly equal.
