所有这些都是新手,我正在尝试按照本指南进行网络摄像头校准,并使用下面的代码.我收到以下错误..
OpenCV错误:在collectCalibrationData中断言失败(ni> 0 && ni == ni1),文件/build/buildd/opencv-2.4.8+dfsg1/modules/calib3d/src/calibration.cpp,第3193行
cv2.error:/build/buildd/opencv-2.4.8+dfsg1/modules/calib3d/src/calibration.cpp:3193:错误:(-215)ni> 0 && ni == ni1 in function collectCalibrationData
有人可以解释这个错误是什么以及如何解决它？
(底部完全错误)
