My experience mirrors yours, but I only worked on this for @ 5 months give or take and didn't really have a big tech team to back me up.
The Qualcomm platform, as far as my understanding goes, still uses the PX4Flow. I don't know what packages they have for vision but it uses ROS so I assumed it had some ROS package powering it.
Px4Flow on its own is insufficient, but I was under the impression that it is able to calculate velocity even with variable distance camera-to-surface, they do have the ultrasonic sensor there and apparently, adding a lidar greatly improves performance.
- fest 10y agoQualcomm platform has different camera and is directly connected to SoC, so I doubt they share anything with PX4Flow. PX4Flow can calculate velocity when camera-to-surface distance varies, no doubt about it. The problem is when single frame contains features at various distances (e.g. lidar/sonar measures distance to ground, but half of the frame also sees table which is a lot higher).
