Can someone tell me what causes my scans to be distorted?
I have used this very same setup successfully many times before. But suddenly I'm getting distorted scans. The scan from my calibration panels is also distorted which leads me to believe that the problem lies in the calibration step.
I have attached two screenshots. One of my calibration panels, which appears flat and the scan made with that calibration.
The calibration goes through successfully and the calibration angle is about 27degrees and the vertical triangulation is 0.07.
I'm using the david 4 software and a BenQ projector. My camera is a pco 1LA. As mentioned before it used to work perfectly fine up until a week ago.
