How do I use mavsdk with ROS 1(melodic or noetic) for camera?

I’m trying to object detection using Jetson nano drone with px4-mavsdk-ros1 (melodic and noetic, I have two computers).
I’m making the whole script for object detection with drone flight(arm/takeoff/moving/land).
But I can’t figure out any information about camera information.
Please help me how to bring camera information using mavsdk-ros.
(I’m not sure of using ROS for bring camera information).

Thank you!!
