findChessboardCorners(image, board_sz, corner, CV_CALIB_CB_ADAPTIVE_THRESH + CV_CALIB_CB_FILTER_QUADS);
It works fine for most cameras, but fails(find 0 corners) when I use a fisheye camera. I tried different combinations of the operation flags but still cannot make it work. Any suggestion in this situation? Does it mean that findChessboardCorners() won't work for images with large distortion, like those from fisheye cameras?
