5 months ago A few bits of movement on this:
- gstreamer videobalance: might work but not ideal
- Tried gstreamer frei0r-filter-3-point-color-balance and frei0r-filter-white-balance. Might work but frei0r is GPL => don't want to invest too much into this
- TODO: try gstreamer glcolorbalance
- Maybe easiest to just PIL balance for now when saving snapshots (image processing pipeline). Won't be live but fine for now
- If its easy to roll in: being able to set a high software gain is useful in some scenarios such as low light IR imaging
The problem: UVC can only do color temperature correction, which has multiple issues
Proposed solution: collect color calibration data against the white target. Then use that to correct captured images
