8.1. FAQ

8.1.1. Unexpected Crash

If the camera node crashes unexpectedly, it will generate a crash log in the current running directory: Log/camera_crash_stack_trace_xx.log. Please send this log to the support team or submit it to a GitHub issue for further assistance.

8.1.2. No Data Stream from Multiple Cameras

Insufficient Power Supply:

  • Ensure that each camera is connected to a separate hub.

  • Use a powered hub to provide sufficient power to each camera.

High Resolution:

  • Try lowering the resolution to resolve data stream issues.

Increase usbfs_memory_mb Value:

  • Increase the usbfs_memory_mb value to 128MB (this is a reference value and can be adjusted based on your system’s needs) by running the following command:

echo 128 | sudo tee /sys/module/usbcore/parameters/usbfs_memory_mb

8.1.3. Additional Troubleshooting

  • If you encounter other issues, set the log_level parameter to debug. This will generate an SDK log file in the running directory: Log/OrbbecSDK.log.txt. Please provide this file to the support team for further assistance.

  • If firmware logs are required, set enable_heartbeat to true to activate this feature.

8.1.4. Why Are There So Many Launch Files?

  • Different cameras have varying default resolutions and image formats.

  • To simplify usage, each camera has its own launch file.
