通过opencv视觉库对摄像头进行视频读取-Video camera read by opencv visual library

通过一张图片基于张正友标定的2D视觉标定，其结果为一个单应性矩阵，基于Opencv的角点提取，标定的计算是自己编写，内有注释和原理，已在工程实践中得到应用。-Zhang Zhengyou based 2D calibration for camera calibration by a picture, the result is a homography, extraction based on corner Opencv, the calibration is calculated to wr

这个是一个基于opencv的视觉处理，主要功能是视觉跟随-This is based on opencv visual processing, the main function is to follow the vision
