CV_CALIB_CB_NORMALIZE_IMAGE- normalize the image gamma withEqualizeHistbefore applying fixed or adaptive thresholding. CV_CALIB_CB_FILTER_QUADS- use additional criteria (like contour area, perimeter, square-like shape) to filter out false quads that are extracted at the contour retrieval stage. 3...
cv::CALIB_CB_ADAPTIVE_THRESH:自适应阈值化。 cv::CALIB_CB_NORMALIZE_IMAGE:归一化图像亮度,通常和ADAPTIVE_THRESH一起使用。 cv::CALIB_CB_FILTER_QUADS:筛选出只有四个顶点的四边形。 cv::CALIB_CB_FAST_CHECK:快速检查模式,不做角点精确检测,用于减少计算时间。适合用于初步筛选。 返回值: 返回值为bool类型。

CV_CALIB_CB_ADAPTIVE_THRESH - 使用自适应阈值(通过平均图像亮度计算得到)将图像转换为黑白图,而不是一个固定的阈值。 CV_CALIB_CB_NORMALIZE_IMAGE - 在利用固定阈值或者自适应的阈值进行二值化之前,先使用cvNormalizeHist来均衡化图像亮度。 CV_CALIB_CB_FILTER_QUADS - 使用其他的准则(如轮廓面积,周长,方形...
