Problems to specify which camera to open

[martenf9]

Hello,

I have multiple cameras which should be opened with camera_aravis package.
But I have problems to connect multiple cameras because specifying which camera to open does not work.

I tried to follow the given ways with using ROS_NAMESPACE:

"To specify which camera to open, via the command-line:
$ ROS_NAMESPACE=cam1 rosrun camera_aravis camnode Basler-21237813"

Also working with rosparam set I did not receive any results. All the time camera_aravis is stating that "Opening: (any)". The package randomly chooses one of the connected cameras.

I guess the problem appears because I do not give correct camera name as input.
But where do I find the correct name?

I am working with TIS Camera DFK Z30GP031. I have tried to give serial number, model name, IP address and also manually given name ("Cam_02") via Windows software GigE Cam IP Config as input. Nothing worked so far. Can anyone help me how to specify which camera should be opened?

Thank you very much in advance.

Hi use arv_tool to find the camera guid and set it as a parameter. You can also set the camera guid in the camera settings using the basler ui.
