Camera Calibration Intrinsic Parameter Verification

Hello All,

I’m trying to calibrate a stereo camera pair. I’m using the openCV and chessboard calibration methods to calibrate the cameras. I want to understand how I can verify whether the camera calibration parameters are correct or not. For example, when we get the intrinsic matrix, it has a focal length value in pixels. So if I’m using a 6mm lens, then should the camera calibration result match the actual focal length? That is, if I multiply the focal length in pixels (that we found from the intrinsic matrix) with the pixel size in micrometers, should the result match the actual focal length of the lens?

Thanks and regards
Kapil
