Calibrating V1 and V2 #12

Open dgalland opened 5 years ago

Hi Richard ! Here are the results of my comparison of the calibration for cameras V1 and V2 with a non-stock lens.

  1. To get the right table you have to run the script with hflip = vflip = True for V2 and hflip = vflip = false for v1, then the table works in all four cases!
  2. The "openloop" script gives much better results than the script on the Bayer capture.
  3. It appears that the camera V1 requires very little calibration, there is no drift of colors but only a central circle less bright.
  4. Even with a careful calibration the V2 camera shows for some yellow-dominant images a yellow central circle. For my project the camera V1 seems a better choice. Dominique
