Re: camera matrix

I am working on a similar project. Here are some good links about calibrating distortion of the lens. These three links bellow can help you calculate lens radial and tangential distortion coefficients if you take some checkerboard images with OpenMV Cam M7. http://www.vision.caltech.edu/bouguetj/cal...
