Hugin cpfind looks for features that are unique, so a chessboard really confuses it. Also for calibration parallax is a big problem, so it is much better to use a scene where the features are a long physical distance from the camera, i.e. go outside and hold the rig high above the ground.
The fine-tune function in the Control Points tab uses different code altogether, this is happiest with corners - when manually picking control points you should always be looking for corners - in this case chessboard-like features are ideal. -- Bruno On 8 December 2016 at 23:47, Ben Knill wrote: > > I'm attempting to use Hugin as a video stitcher (with FFMPEG) - this is going > well, however I'm wondering if a rig could be calibrated by photographing > something that is placed around the camera, i.e. a light box with the camera > inside, with something printed on it that would make it really easy for Hugin > to automatically find control points?
