利用对称的园盘格标定相机一般就会用到findCirclesGrid这个函数。如下图 虽然从找点到标定opencv都提供了现成的函数,但是参数的设置上还是得注意。 findCirclesGrid一般这么调用 std::vector<cv::Point2f> p; cv::Size s; s.height = 6; s.width = 9; found1 = findCirclesGrid(img, s, p, CALIB_CB_...

findCirclesGrid是OpenCV库中的一个函数,用于在给定图像中查找具有特定网格结构的圆形。它的主要作用是在图像中找到一个圆形网格的角点,并返回这些角点的坐标。该函数广泛应用于相机标定、姿态估计、物体检测等场景。 2. findCirclesGrid函数的主要参数及其含义...
1.标定图案 OpenCv中使用的圆形标定图案如图1所示:OpenCv中,使用圆形标定图案用到的函数为 cv::findCirclesGrid()。 如果使用halcon在线抓图标定,可以有效避免图像品质问题,从而大幅度提高标定精度,预计标定精度和OpenCv标定相当或者更高。 55120 OpenCV双目标定 ...

According to the documentation, patternSize should be (points_per_row, points_per_colum). However, it seems that only when I set patternSize as (points_per_colum, points_per_row) can make the return value retval of findCirclesGrid() become True....
