亚像素级cvFindCornerSubPix角点检测，可较为精确地对角点进行检测-The subpixel cvFindCornerSubPix corner detection

基于Opencv和C++, 使用harris算法， 对输入视频，提取亚像素级角点的个数和坐标。-base on Opencv and C++, using Harris algorithm, output the subpixel corners number and coordinate of video.

读取每一幅图像，从中提取出角点，然后对角点进行亚像素精确化，摄像机定标， 对定标结果进行评价，保存定标结果。-Read each image and extract the corner, then the diagonal points subpixel precision, camera calibration, the calibration results were evaluated on save calibration results.

使用OPENCV编写的亚像素边缘提取，其中包括运行所需库，及测试数据；可直接运行。-Written using OPENCV subpixel edge detection, including running the needed libraries, and test data Can be run directly.
