ubuntu系统下相机标定程序出现 terminate called after throwing an instance of 'cv::Exception'
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(3.4.3) /home/dabing/opencv/modules/calib3d/src/calibration.cpp:3394: error: (-215:Assertion failed) nimages > 0 in function 'calibrateCamer
出现这这种问题 该如何解决?
