I bought an Intel Realsense last year (2 generations ago) and this is much more powerful, esp. in localization . If you buy this, expect it to be obsolete in about 6 months

Back up a bit... what exactly is a tracking camera?

It's a 'Simultaneous Localization and Mapping device' (SLAM) that will give you its position, velocity and acceleration in 3D. There's quite a large [1] literature on the subject.

Interesting. I wonder how it compares in capability to these algorithms, which are in Nvidia’s Redtail SDK: https://youtu.be/T7-IxCW1UlA

Neat, thanks for linking this, I hadn't heard about Redtail before.

This camera only tracks its own pose - it doesn't output a full depth map, according to the FAQ.[1]

The visual odometry algorithm ("Elbrus") in that video can supposedly be run on an NVIDIA Jetson board (unclear which one) at 30fps.[2] It seems like this runs on the CPU, which is pretty impressive.

The Elbrus demo app uses the $450 ZED stereo camera[3], compared to the $200 T265[4], though there's probably nothing stopping someone from using Elbrus with cheaper cameras, including possibly this one.

Nice project! Your 3D printed case for the stereo pair removes a lot of potentially useful information for the feature extraction algorithm. If it can help, I have an old project where we mounted a realsense (R300 if I remember well) on Hololens. You can inspire from our 3D printed mount, the CAD is available here : http://vision.gel.ulaval.ca/~jflalonde/projects/hololens3d/i...

This looks great! In reality, our casing only covers really small area, but we are always looking to improve :).

I have a Jetson Xavier and dual $50 PS4 stereo cameras on my robot and will be trying the Nvidia algorithms.
