Hi @zqj2000 Your comment got me closer to solving a similar issue. I just replied to the full thread with some code. I feel like I'm missing a step rectifying the depth data so the calculations work. If you have any additional insight I would greatly appreciate it. Thank you!

Hey guys. Did you manage to figure this out? I’ve successfully accessed the actual depth at the pixels I’m interested in but my calculations to find the real world distance between 2 points in the image are also inaccurate. The number is roughly half what it should be. Hope you narrowed in on a solution. Thanks!
