Hello, I try to learn camera calibration. I used `cv::calibrateCamera`

to obtain intrinsic camera matrix, distortion coefficients, rotation vectors, and translation vectors. How do I get the extrinsic matrix for that camera? I learned that I need to find a rotation matrix and translation matrix to build an extrinsic matrix but `cv::calibrateCamera`

gives me rotation vector and translation vector for each calibration image, as a result, if I use cv::Rodriguez I get rotation matrices for each calibration image.

How do I create one **P** = [**R** | **t**] for my camera?
