HELPFUL: How to set camera color config in launch file

[nbaddorf]

This is to help others running into the same issue I am had.

My cameras default image was messed up from the color settings in video_stream_opencv. Rosparam didnt work for me. I found this stack exchange https://robotics.stackexchange.com/questions/84000/load-parameters-using-roslaunch-saved-as-yaml-from-rqt-dynamic-reconfigure and this worked for me.

Run rosrun dynamic_reconfigure dynparam dump /node config_raw.yaml to download a yaml file of the parameters. For me it was rosrun dynamic_reconfigure dynparam dump /webcam/webcam_stream config_raw.yaml

Then go in and modify that yaml file to set the color settings to what you want.

Then add to your launch file this: <node name="dynamic_reconfigure_load" pkg="dynamic_reconfigure" type="dynparam" args="load /camera_node_name $(find my_package)/params/config_raw.yaml" /> Again, I had to change camera_node_name to /webcam/webcam_stream

Hope this helps
