hartley弱相机标定的立体像对极线校正。输入是立体像对对应的匹配点,输出是已经校正好的图像
这里对图像的角度有要求,如果拍摄角度太大
可能校正不了
而且匹配点对的精确性也有要求,建议最好经过错误点剔除之后的匹配点作为输入-epipolar rectification

立体视觉相关的程序,这部分需要先了解图像和摄像机之间的对立关系,并对极线几何比较了解,先把原理熟悉了以后,具体到编程上就会轻松一点,整体还是比较耗时的。具体来说,程序使用SSD得到匹配点,然后根据匹配点计算出基本矩阵,最后计算出匹配点相关的极线-Stereo vision procedure, this part of the need to understand the antagonistic relationship between the image and the camera, an
