Public bug reported:
Binary package hint: python-opencv
Using version 1.0.0-3ubuntu3 of python-opencv.
The documentation produced via "pydoc opencv.cv.cvCalibrateCamera2" is:
cvCalibrateCamera2(CvMat object_points, CvMat image_points, CvMat point_counts,
CvSize image_size, CvMat intrinsic_matrix, CvMat rotation_vectors=None, CvMat
translation_vectors=None, int flags=0)
As you can see it lists 8 arguments. However, when providing all 8, it raises
the exception:
TypeError: cvCalibrateCamera2() takes at most 7 arguments (8 given)
Even when providing the bare minimum of arguments (5, according to pydoc) with
all the matrices set up properly (in other words, exactly the same as a working
version in C), it raises this error:
RuntimeError: openCV Error:
Status=Bad argument
function name=cvCalibrateCamera2
error message=the output array of rotation vectors must be 3-channel 1xn or nx1
array or 1-channel nx3 or nx9 array, where n is the number of views
file_name=cvcalibration.cpp
line=1324
I have noticed that in C, the function prototype of cvCalibrateCamera2 includes
an extra argument "distortion_coeffs":
void cvCalibrateCamera2( const CvMat* object_points, const CvMat* image_points,
const CvMat* point_counts, CvSize image_size, CvMat* intrinsic_matrix, CvMat*
distortion_coeffs, CvMat* rotation_vectors=NULL, CvMat*
translation_vectors=NULL, int flags=0 );
Could it be that the mapping from Python arguments to C arguments is
ill-defined?
