Hi ! I want to use the cv::findChessboard() function to calibrate my camera. let'S say I've a 4x5 chessboard how can I get information abot the corners if only a a part of my chessboard has been detected say 3x4 or 3x5 or 4x4 etc.
thanks in advance for your help
Basically the camera calibration uses gradient information to look for interesting points, based on the Harris Corner detector. The function you are citing doesn't exist but I think you want to take a look at findChessboardCorners() which looks for interesting points, which can then be used to calculate the projection matrix.
I just said the function looks for corners, which is essentially each part where 4 white and black squares join together. A half chessboard will reproduce these areas also so they will be detected in fact!
This seems more and more like a high school project that needs to be solved. I directed you to the functions documentation page, which clearly states that one of the arguments is 'OutputArray corners'. As you could have guessed these will contain the actual information you are looking for. Please, I urge you to put some effort in it :) We all needed to learn to take the first steps sometimes.
