Crash at the end of the sequence #3
Description
Independent of the start and end point of a recording, I get the following error. Any idea, what could go wrong?
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.5.4) ./modules/calib3d/src/calibration.cpp:1213: error: (-215:Assertion failed) fabs(sc) > DBL_EPSILON in function 'cvFindExtrinsicCameraParams2'
