why there is a circle in undistort image after calibration
Use the example code , and set flag in the function calibrateCamera flag |= CALIB_RATIONAL_MODEL; flag |= CALIB_THIN_PRISM_MODEL; flag |= CALIB_TILTED_MODEL;
Use the output calibrate parameters to do undistortion, there is a circle, why?
This circular discontinuity was also discussed here, maybe this will trigger some additional thoughts/experiment ideas:
