I'm using OpenCV calibrateCamera function to extract intrinsic end extrinsic parameters of my camera. I have a big problem with the extrinsic one (rotation and translation) because the rotation matrix, that should be a 3x3 matrix, it's only a 3x1. Does someone know why I have this output or how can I use it? Thanks in advance!

You get a vector which is actually the axis-angle representation of your rotation. You can convert that in a 3x3 rotation matrix using the Rodrigues formula:
