How to match depth frame with RGB frame in astra stereo s u3?

[OhadSG]

If it’s still relevant view my comment about this problem here

Color to depth stream registrations, Astra Embedded S

The depth resolution is 640x400 (using openni2) and the RGB resolution is 640x480 (opencv). If you delete the lower 80 rows of RGB image, making the frame 640x400, then you can solve half of the problem.

Let me know if it works
