Multiple USB Cameras
Hello,
I'm actually working on a project where i should implement multiple USB Basler Cameras with the pylon_camera driver.
I already get successfully an image, but only from a single camera.
I set each camera a different UserDevice ID ("camera_01" and "camera_02") and reset them afterwards. I changed the Parameters in the default.yaml file at catkin_ws/src/pylon-ros-camera/pylon_camera/config as mentioned in the READ_ME File in the package folders: device_user_id: "camera_01" but it only detect one camera with its user ID. It tried also to add both camera-IDs (i tried something like: device_user_id: "camera_01", "camera_02") to the parameter but i got an error.
I couldn't find any information how this driver work with multiple cameras. Is it necessary to run one node for each camera? Or do i have to switch between the user IDs? And how do adapt some settings of a specific camera with rosservice, how do i adress the camera?
And last but not least, by changing the frame_rate at the parameters in the default.yaml file at 30, i got following error: "Desired framerate 30.00 is higher than max possible. Will limit framerate to: 14.83 Hz". How could i reach a higher framerate? By adapting the USB transfer size?
i would appreciate any help! Greetings gewi1011
