Hello,
I have noticed that in some cases such as the ones in the images I am attaching, the cvFindChessboardCorners reports finding the correct number of corners although the corners are outside of the image. This tends to happen when the calibration target is right next to the edge of the image, so I am wondering if there is an easy way to add a a check for this.
I generated the images I am attaching with OpenCV [[OpenCV]] 2.1, using the CV_CALIB_CB_ADAPTIVE_THRESH |
CV_CALIB_CB_NORMALIZE_IMAGE |
CV_CALIB_CB_FILTER_QUADS
flags for the function call.
In case I am breaking any rules about ticket submissions, I apologize in advance.
Thanks, Cris.
