ERROR: failed to start modalai vision lib

Hi, voxl-vision-px4 error

tell me what could be the reason?

Chad Sweet · 15 Feb 2021, 16:12

Do you have another process using the tracking camera? It looks like it cannot open the tracking camera.

@Chad-Sweet Launching on the VOXL Flight Deck I just received. Turned on, passed the wizard and get this error.
What else can a tracking camera use?

Chad Sweet · 15 Feb 2021, 16:38

It would have shipped with everything tested and working. What do you mean by "passed the wizard"?

@Chad-Sweet when connecting QGC, there was no odometry in the mavlink inspector. After that I ran voxl-configure-modalai-vl

Pavel Ardashov · 16 Feb 2021, 09:26

@Chad-Sweet now the odometry data is in the mavlink inspector, but x and y = 0

Hello, When you ran the wizard, what did you enter for the camera configuration question, it should have been option 3 (hires+stereo+tracking) for a flight deck.

Do you mind running voxl-vision-px4 manually in odometry debug mode to see if VIO is working and share the output? You can use this command:

voxl-vision-px4 --debug_odometry

Thanks!
