Opencv intrinsic calibration

Web30 de jul. de 2016 · updated Jul 31 '16. There is at least a problem with your intrinsic calibration. Two of your entries are exactly zero which looks suspicious. The problem here is the flag you pass to calibrateCamera. You pass 'CALIB_CB_FAST_CHECK' which is a flag for the checkerboard detection. WebCalibration is only as accurate as the calibration target used. Use laser printed targets only to validate and test. Proper mounting of calibration target and camera. In order to minimize distortion and bow in larger targets, mount them either vertically, or laying flat on a rigid support. Consider moving the camera in these cases instead.
