Preliminary Checks

Description

Hello,

I ran the zed-mini for less than an hour with the zed ros2 wrapper as well. I also opened an instance of rviz2 so the Point Cloud topic and Image topics had subscribers. I did not get this error when I was not in NUERAL mode.

The wrapper eventually threw this error:

[zed_wrapper-2] [2024-10-18 16:29:42 UTC][ZED][WARNING] IMU initialization failed, gyro bias too high. Found -0.05130885193141408 -0.042381061746106743 -0.04324537508178055 vs factory calibration 0.0009650529221373622 0.0006340666013872853 0.0019884070958669803
[ERROR] [zed_wrapper-2]: process has died [pid 224052, exit code -11, cmd '/home/ubuntu/Documents/ws/install/zed_wrapper/lib/zed_wrapper/zed_wrapper --ros-args -r __node:=zed_node -r __ns:=/zed --params-file /home/ubuntu/Documents/ws/install/zed_wrapper/share/zed_wrapper/config/common.yaml --params-file /home/ubuntu/Documents/ws/install/zed_wrapper/share/zed_wrapper/config/zedm.yaml --params-file /home/ubuntu/Documents/ws/install/zed_wrapper/share/zed_wrapper/config/ffmpeg.yaml --params-file /tmp/launch_params_vu94edf4']

I'm confused because it doesn't look like there is an error associated with the node dying.

Steps to Reproduce

  1. Connect zed mini to Orin nano
  2. Run zed ros2 wrapper with default parameters
  3. Run rviz2 with subscriptions to 1 Point Cloud and Left Image topic

Expected Result

Both pointcloud and image topics to be running at the same frequency no matter how long wrapper has been up.

Actual Result

Zed ros2 wrapper crashed with the error described above.
