We are trying to run the human detection functionalities provided by
Stereolabs and zed_ros_wrapper using 4 ZED2 cameras and a Jetson
Xavier with Jetpack 4.5.
We have tried connecting the 4 cameras to a PCi board as recommended
by you but we are encountering issues with one or more cameras failing
(after a while) and not being able to start again. These are the main
error messages we get and sometime we get no error messages at all
despite having camera failure:
1)ZED connection → LOW USB BANDWIDTH
2)ZED connection → CAMERA STREAM FAILED TO START
I have seen disconnecting and reconnecting the usb cables sometimes
helps to resolve the issue but is not a certain fix.
I suspect this to be a power issue.
I noticed a mismatch between the information on the adaptor that came with Jetson and the information give on the box.
Adaptor info: 19.0V–3.42A
Box info:9V–10A, 20V–4.5A
We are working on the power limits with the 4 ZED2 cameras and I need to verify this information.
Thanks in advance for your help
