I started from the tutorial implementation, but there seems something wrong. The camera is looking down on a table and i use a chessboard with an area that covers about 12 or 14 of my total image. ![]() So my first question is: is it ok that i move my chessboard over this table Or do I have to make some 3D movements in order to get some good resultBecause I was wondering: how does the function guesses the distance between the table and the camera He has only a guess of his focal point, and he has only one eye, so there is no depth vision. My second question: how does the bloody thing work:p Can anyone show me some implementation of this function Open Cv Face Detection Python Thx user2812874 user2812874 2 Answers the camera calibration needs a seed of points to calculate the camera matrix and the the position of the central point of the camera, and the distortion matrices, if you want to use a chessboard you have to take in consideration its dimension(I never used the circles function because the detection of chessboard is easier ), the dimension of the chessboard should be pair X unpair number so you can get a correct rotation matrix the calibration function needs minimum 8x set of chessboardCorners and ( I use 30 tell 50) it depends on how precise you want to be.the return value of the calibration function is the re-projection error this should be near to zero if the calibration is good.the cameraCalibration take a the size of used chessboards ( you can use different chessboardSize) and the dimension ( in mm or cm or even m etc. By the way after getting the chessboardCorners you have to refines them with the function CornerSubPix you can set how good the refinement is in the function parameter.
