This example demonstrates how to start the camera node and streaming with two cameras using the rs_dual_camera_launch.py.
ros2 launch realsense2_camera rs_dual_camera_launch.py serial_no1:=<serial number of the first camera> serial_no2:=<serial number of the second camera>
Let's say the serial numbers of two RS cameras are
ros2 launch realsense2_camera rs_dual_camera_launch.py serial_no1:="'207322251310'" serial_no2:="'234422060144'"
Or with underscore as prefix (this way must be used when there are leading zeros (0) in the serial number. e.g.
ros2 launch realsense2_camera rs_dual_camera_launch.py serial_no1:=_007322251310 serial_no2:=_234422060144
How to know the serial number?
Method 1: Using the rs-enumerate-devices tool
Method 2: Connect single camera and run
ros2 launch realsense2_camera rs_launch.py
and looking for the serial number in the log printed to screen under "[INFO][...] Device Serial No:".
