Failed to start Stereo Camera Nodelet
-
I get this error every other time. for the first launch it executed perfectly but subsequent lanches throw error. Basically if it run perfectly and if i interrupt it by pressing ctrl + c and than run again it starts saying could not load nodelet. And many a time it says could not open camera ID = 2. Unable to open camera.

I even tried setting it as slave and not master as recommended over here [https://docs.modalai.com/voxl-cam-ros/](link url)
but after showing
Monotonic offset
it throws error

Can you please provide us with your hardware setup? What camera(s) do you have connected?
Can you also run
voxl-version
and provide us with the output?Thanks!

Also, only one camera can be master in the libcamera architecture. If voxl-vision-px4 has VOA enabled, and is using the stereo cameras, is_cam_master needs to be set to false. In the log above is_cam_master is set to true

I am using voxl-flight deck
cameras are same that comes with flight deck-> stereo camera, hires and optical flow cameraThis is the voxl version currently in use in my setup

Yes I tried both setting it to true and false. But once you start launch camera and the terminated and try to launch again it does not launch.
