Detailed description

solvePnPRansac calls solvePnP wihch calls cvFIndExtrinsicCameraParams2 using less than 6 points.
Then, the following error is raised:
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.3.0) /home/salinas/Libraries/opencv/opencv-4.3.0/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

Steps to reproduce

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues,
  answers.opencv.org, Stack Overflow, etc and have not found solution
• I updated to latest OpenCV version and the issue is still there
• There is reproducer code and related data files: videos, images, onnx, etc
