I have problems to get the driver working properly with more than one camera. Has it ever been tested or I am just doing something wrong?

anqixu commented 10 years ago

It should work fine. For example, you can duplicate the 'ueye_cam_nodelet' node in rgb8.launch, rename the name of the nodelet, and change to different camera IDs. Alternatively, open master_slave_rgb8.launch, find '', and change True to False.

Let me know if you have more troubles.

Yes that seems to work, but following error occures: [ERROR] [1394039248.287967045]: Tried to advertise a service that is already advertised in this node [/camera/set_camera_info]

If i rename the camera_name to something like camera2 , the error disappears, but then the 2nd camera is not working properly

Make sure that each camera node in the launch file have UNIQUE values for following fields:

Furthermore, you should set the "ext_trigger_mode" ROS parameter to "False" for all of your nodes.

Please see http://www.ros.org/wiki/ueye_cam for more details.

Hi, I have problems with running the ros node too. The programm only starts each second time. i.e is set to free run mode each second time. Could there be a problem with a publisher/subscriber inside the code or might it be a configuration issue? Best regards philfromger

Please open a new issue rather than appending onto this solved issue. Also, please provide the following details (and further descriptions) so that I can better help debug the situation:
