Calibration / Displacement #10

Open Flacedoo opened 7 years ago

Flacedoo commented 7 years ago

I've encountered an error while using the duo3d mlx for marker detection with apriltags. I think it's an error in the calibration - but the apriltags node which gives me (relative to the camera) marker positions has a displacement. When Markers are straight in front of the camera (which appear in the middle of the image as well!) , it gives me an offset to the side. I calibrated the camera like 100 times, but this only changed the offset a little. Anyone has ideas? Is there maybe a way to write a manually generated calibration to the camera? The calibration app doesn't give me this possibility.
