Crash when using 5 calibration points for extrinsic calibration
Crash when using 5 calibration points for extrinsic calibration
4 should be enough but the report says:
Application Specific Information: abort() called terminating with uncaught exception of type cv::Exception: OpenCV(4.5.5) /Users/petrack-ci/dev/opencv/modules/calib3d/src/calibration.cpp:1173: error: (-2:Unspecified error) in function 'void cvFindExtrinsicCameraParams2(const CvMat *, const CvMat *, const CvMat *, const CvMat *, CvMat *, CvMat *, int)'
DLT algorithm needs at least 6 points for pose estimation from 3D-2D point correspondences. (expected: 'count >= 6'), where 'count' is 5 must be greater than or equal to '6' is 6
