Proposal

The zed.launch.py, zedm.launch.py, zed2.launch.py and zed2i.launch.py are three Python scripts that automatically start the ZED node using "manual composition", loading the parameters from the correct "YAML files" and creating the camera model from the correct "URDF file".

Note: You can set your own configurations modifying the parameters in the files common.yaml, zed.yaml zedm.yaml, zed2.yaml and zed2i.yaml available in the folder zed_wrapper/config. For full descriptions of each parameter, follow the complete guide here.

This is not completly correct as a lot of the settings you make in the yaml files are overwritten by the launch files.

For example I had to change the command I use to run the wrapper because the settings I made in the yaml files didn't work anymore when I checked out the most current commit.

ros2 launch zed_wrapper zed2.launch.py publish_tf:=false publish_map_tf:=false base_frame:="camera_mount"

Also the link to the parameter description doesn't work at the moment.
