Hello, @yoterel
Great implementation in your setup.
I'm sorry, but I don't know the exact reason for that weird artifact. I haven't encountered such a problem.
I guess you should
- Increase the number of projection patterns (1.5 to 2.0 times more than the minimum requirement). It can be robust against noise, and your artifact may be suppressed.
Additionally, make sure when you capture the images.
- Set the camera setting manually (i.e., exposure time, gain (iso), aperture, white balance). Do not rely on auto. It may change the setting while capturing sequential images.
- Disable the gamma correction. While estimating the light transport matrix, I assume the camera response function is linear.
- If you use a DMD or laser scanning-based projector, you must consider the camera's exposure time. Check the raw image, and it does not have a weird pattern.
