Camera lens calibration frozen

Hi, I got a new camera for the Ortur LM1 because I wasn’t satisfied with the previous.
But during the calibration of the lens after a random number of capture the all thing freezes.
It’s very frustrating because it’s very random, sometimes I can go through the first step and sometimes not.

What camera?

166° CMOS OV5648

The things that stand out are:

  1. Your paper is not flat. When we say flat, we mean “machined surface” flat, not “I ironed this last month” flat. :slight_smile:

  2. The shadow across the dots pattern is going to make it harder for the image analyzer to find the pattern. You should jog the laser out of the way and get the clearest image you can.

OK thank you I will try all this. :laughing:
