CodeĪs mentioned above, we need at least 10 test patterns for camera calibration. For better results, we need at least 10 test patterns. We know the coordinates of these points in real world space and we know the coordinates in the image, so we can solve for the distortion coefficients. We find some specific points of which we already know the relative positions (e.g. To find these parameters, we must provide some sample images of a well defined pattern (e.g. \\]Įxtrinsic parameters corresponds to rotation and translation vectors which translates a coordinates of a 3D point to a coordinate system.įor stereo applications, these distortions need to be corrected first. Radial distortion can be represented as follows:
