1.28. Is it possible to obtain the internal parameters and distortion correction coefficients used during camera calibration from the camera?#
No.
The camera’s internal parameters (\(f\), \(Cx\), \(Cy\)) and distortion correction coefficients (\(k_1\), \(k_2\), \(k_3\), \(p_1\), \(p_2\)) are not recorded inside the camera, so these parameters cannot be obtained.
You will need to calculate these parameters using software and a checkerboard, etc.
