1.7.+ Mintion Lasercam can no longer Update Overlay

My Mintion LaserCam worked fine up until 1.7.0, tried 1.7.01 today Still doesn’t work. The camera video comes through in the preview but any attempt to hit the Update Overlay yields a weird white gradient effect on the board and if I try camera calibration the option to take the photo of the calibration markings is just solid black.

I have the same issue.

Hi there! Sorry you’re having issues… first, check if you have the “Current calibration - reset resolution” option in the camera lens calibration presets menu:

If so, your calibration was incorrectly linked to the wrong camera resolution by 1.7.00 and that might fix it.

If you are going through the full calibration process using the dots or apriltags pattern, the “undistorted” camera view on the right may need a couple of samples before it begins to come good, and might remain black (or heavily distorted) until then.

It’s working with what it’s got so far. As long as you are getting a sufficiently low error score just trust the process and keep going. There is an art to it.

If you’re still having trouble and want to check if your calibration is the problem, you can try the “None - precalibrated camera” option. That ‘passes through’ the camera image unchanged, so in your case you will still get a distorted final image but it’s good as a test.
