运行run_calibrate_camera.py 添加参数 -fishe--nogest 运行可以识别角点，但按c标定会出现如下错误，使用的是usb鱼眼相机。感谢老师 #45

看提示似乎是你的输入图像不符合要求。你有没有调整标定板的位置多拍几张？

感谢回复，我采用的是标定版不动，只移动相机的方式。

理论上这也可以。你是所有的标定都失败吗？

对的 目前我只是在程序中做了如下修改添加了这几个参数：

运行可以进行角点提取，但是按C标定后，就会出现下方的错误：

对的，我只是在parameters中添加 -i 3 -fisheye --no_gst ，参数，然后运行，可以捕捉到角点，但是按c标定后，显示如下错误。 OpenCV(3.4.1) Error: Internal error (CALIB_CHECK_COND - Ill-conditioned matrix for input array 0) in cv::internal::CalibrateExtrinsics, file C:\projects\opencv-python\opencv\modules\calib3d\src\fisheye.cpp, line 1414 Traceback (most recent call last): File "C:\Users\whd\Desktop\surround-view-system-introduction-master (4)\surround-view-system-introduction-master\run_calibrate_camera.py", line 191, in main() File "C:\Users\whd\Desktop\surround-view-system-introduction-master (4)\surround-view-system-introduction-master\run_calibrate_camera.py", line 164, in main (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 30, 1e-6) cv2.error: OpenCV(3.4.1) C:\projects\opencv-python\opencv\modules\calib3d\src\fisheye.cpp:1414: error: (-3) CALIB_CHECK_COND - Ill-conditioned matrix for input array 0 in function cv::internal::CalibrateExtrinsics
