No camera view in update overlay


Live camera view okay in teh camera control window but I get this gray grid picture after clcking update overlay. Camera had been calibrated. When I go to the calibration option all I see is a black picure

It looks like part of the image is making it … if you cover the camera so the preview stream goes black and ‘Update Overlay’ again is the overlay image darker?

Please add a screenshot here of what you see in the Camera View when you open the Lens Calibration Wizard and select the ‘Creality Falcon Camera’.

Update overlay doesn’t change when the camera is covered. I have attached the requested screenshot

I have this exact same problem, I posted this question a few days ago. I did not get any responses.


Ok thanks, I understand now that your black picture problem only occurs after lens calibration, although I’m now confused about how you would have been able to perform the alignment procedure.

As a troubleshooting exercise, please calibrate again but select the '(None- precalibrated camera)’ option.

After this, if the ‘Update Overlay’ picture comes out looking a lot better?, then that isolates the problem to the lens calibration data (which I suspect is the source of your issue), and to fix that you have to re-calibrate the lens (and then re-align).
