I have a virtual camera placed somewhere in the world and I would like to now its parameters. Usually, ROS-topic /camera_info contains information about the camera, like camera matrix, for example. Is there any possibility to get this information from Sphinx without using ROS-plugins?
You can also retrieve the camera lens parameters published on its lens/info topic with parrot-gz: parrot-gz topic -e "~/bebop2/body/horizontal_camera/lens/info"
It seems like CameraSensor message does not have intrinsic camera matrix that I am looking for. I thought, maybe your last paragraph would help, but I could not find neither the parrot-gz command nor any lens related topics with a simple gz topic -l. Would you give me a tipp about what I am doing wrong?
parrot-gz is just an alias for gz. You can only see lens/info topics for wide-angle cameras (sensors with type wideanglecamera) like the front camera of Bebop 2.
