<![CDATA[VOXL LOW_FEATURES]]>Hello,

I am attempting to get VIO to work.
I know it is not working because I can not see x & y go to non-zero values in QGC.

My main concern is when I run "voxl-inspect-qvio" I see this
7460ef47-09cd-4b85-9c5e-727c8bbfabef-image.png

It seems like the cameras are not picking up on things that are "interesting". Or anything they can use for reference to see movement.

When running voxl-vision-px4 -o no debug statements are sent after initial startup output

The tracking camera cannot produce the resolution that VLC is receiving.

  • The tracking camera is not properly connected
  • The tracking camera is plugged in backwards
  • There is another process that is accessing the tracking camera preventing voxl-camera-server from accessing. If you tried the old ROS packages, this could be an issue.
  • voxl-configure-cameras does not match what is actually installed. You need to specify the installed configuration, not a subset of what you want to use.

Can you reboot and make sure no other processes are accessing the cameras?

Did you purchase a flight deck? All of this would be pre-configured and tested prior to shipping, so maybe you installed new software?

I am still struggling with opening the tracking camera. I tried to open the camera with RTSP, but can not open it.

The hi-res cameras are working, but the tracking camera is not.

It is weird that it can not open the tracking camera. I believe that there is some way to pull up the camera and verify it is working correct?

I believe it was some ROS launch script. Let me see if I can get the tracking camera up, and will respond when I can verify that it is working.

Thank you!

This will lead to qvio not seeing any features since its not getting any camera frames.
