Description

The current implementation of cv::projectFeatures does not check if given distortion coefficients array is empty. As a result it passes a non-NULL coefficient matrix to cvProjectPoints2 even if there are no distortion coefficients.

On the other hand, cvProjectPoints2 performs some assertions on distCoeffs matrix when it is not NULL (specifically it checks the number of matrix elements and does not allow 0 elements).

I'm confused. The function is clearly declared in one of OpenCV headers:
http://code.opencv.org/projects/opencv/repository/entry/trunk/opencv/modules/calib3d/include/opencv2/calib3d/calib3d.hpp#L489
How come it is not part of OpenCV library?

What function this ticked is about?

If it is about cv::projectFeatures then resolution is fully correct.
If you have found a bug in cv::projectPoints then, please, write a correct title and description.

Thanks,
Andrey

I issued a new bug report (#1700) with correct title and description.

I'm sorry for the confusion.

Thank you,
