if the two cameras are connected to the same host machine, then you must open them by using their serial number or idx, otherwise the ZED SDK always tries to open the camera with the lower idx:
Can you elaborate on this part? There is no “zed_id” defined in the existing launch files. Should I create a common.yaml for each of the cameras and write the id’s there or how should I go about it?
@rallpal Yes, that’s a solution.
However, we can add the
serial_number as parameters for the launch files.
Can you please add a feature request issue on Github to keep track of it?

The launch files have been updated with the new
