Description
- On entry to DLASCL, parameter number 4 had an illegal value
The input is
objectPoints:
0.0328927 0.06368747 0. 0.00922698 0.0687118 0. 0.00922698 0.0687118 0. 0.00922698 0.0687118 0.
imagePoints =
-0.09685596 -0.01165635 -0.45950995 -0.32760567 -0.48671867 -0.31602137 -0.45217826 -0.33057223
cameraMatrix = identity
distCoeffs - zeros
from simple inspection, it seems that the function cannot handle object points that are collinear. so my question is, does this check belong inside the function, or should the user be doing it before the function call? If so, how can i quickly check if a set of 3d points are collinear (basically 2 or more eigen values of the covariance zero 0)

I just want to say that by adding a check on the eigenvalues of the coviariance matrix before calling the function, things stopped freezing for me

Does not seem Python specific. Passing to Vadim for comment.

Thanks! The sample runs fine since r3148, where the problem seems to be fixed
