OpenCV::solvePNP() - Assertion failed

Question

I am trying to get the pose of the camera with the help of solvePNP() from OpenCV.

After running my program I get the following errors:

OpenCV Error:         


        

Answer 1

Step into the function in a debugger and see exactly which assertion is failing. ( Probably it requires values in double (CV_64F) rather than float. )

OpenCVs new "inputarray" wrapper issuppsoed to allow you to call functions with any shape of mat, vector of points, etc - and it will sort it out. But a lot of functions assume a particular inut format or have obsolete assertions enforcing a particular format.

The stereo/calibration systems are the worst for requiring a specific layout, and frequently succesive operations require a different layout.
