I want to use the function cv::findEssentialMat with two different camera matrices. At the moment this is not implemented in the standard five-point.cpp .(https://github.com/opencv/opencv/blob/master/modules/calib3d/src/five-point.cpp). Nevertheless it would be very easy to overload the function using two different camera models. I do not come from a programming background so would it be possible if I just add an overloaded function with additional camera matrices to the data file five-point.cpp in my build directory on my pc?
