Good evening, I'm new here .. I'm sorry if this question has already been asked, it's that I could not find anything about it ... without further ado, let's ask the question. Well I've been looking for an algorithm for Camera calibration, but so far I have not found anything, I just found it in OpenCV, but I did not want to use that library.
I need to photograph a certain color in different Androids devices. The purpose is to get the RGB of this color, but before shooting I need to calibrate the camera, so I got the best possible result.
If anyone knows of a calibration algorithm, or something about it, or if you can tell me a study material, I appreciate it.
