Can't find my devices #4

Hello,

I'm using ROS2 Humble inside a Docker. I've installed both packages:

Right now I can use gc_info -l and get following response:

Seems like both cameras could be found. Now i wanted to stream the Images like i did it before, just using the new command: ros2 run rc_genicam_driver rc_genicam_driver --ros-args -p "device:=:S1128771"

I was trying around with S1128370, S1128771, 000002, jai_01, with and without ":" before and also with default parameters ("*"), but still get the same response "Cannot find device ...":

(my_cv) root@modi:/home/jetson/rc_genicam_driver_ros2/cmake# ros2 run rc_genicam_driver rc_genicam_driver --ros-args -p "device:=:S1128771"
[INFO] [1678909254.121006709] [genicam_driver]: Initializing

[WARN] [1678909256.150590235] [genicam_driver]: Cannot find device ':S1128771'

What am I doing wrong? For me there is no change to my ROS neotic setting, where i could make it work with my cameras.

Thanks for every help :smile:

The rc_genicam_driver for ROS 2 (and ROS 1) are specifically designed for our 3D cameras and will not work for general 2D cameras. The readme starts with "ROS2 driver to configure a Roboception rc_visard or rc_cube". The device discovery specifically filters for our devices. I admit that the error message could be better.

You have probably used the rc_genicam_camera node on ROS 1 before. This supports 2D cameras. This node has not yet been ported to ROS 2.

Thanks Heiko for the quick reply. Ohh, I read that, but I was hoping that it would also be possible for our 2D cameras to get the images easily. If I understand correctly, there is currently no ROS2 implementation for GigE, so we have to write our own node?

Sorry I am not that familiar with Genicam and ROS2. I'm just looking for a simple way to get the images from the camera into my ROS2 docker, as i did in ROS1 before.

Thank you very much.

Closing as it does not pertain to this repo. https://github.com/roboception/rc_genicam_camera is not ported to ROS2 yet, ports are welcome.
