Our team has been sending out supplementary IR light since our product release.
(It's never been explained well, and I've always considered it witchcraft. I've no evidence it's ever helped.)
Today I decided to test this idea, and I made a little video here:
It seems when I add the additional IR light, the data gets worse.
- This is a D435
- I'm using 850nm light.
- The video doesn't show it, but I've tried it with the "high accuracy" preset.
- I've checked the camera distances the Stereo Module
- I've tried it with and without the laser.
If I had to guess... the added IR light overwhelms the projected dots (they disappear), making the camera less accurate.
