Manages advertisements for publishing camera images.
CameraPublisher is a convenience class for publishing synchronized image and camera info topics using the standard topic naming convention, where the info topic name is "camera_info" in the same namespace as the base image topic.
On the client side, CameraSubscriber simplifies subscribing to camera images.
A CameraPublisher should always be created through a call to ImageTransport::advertiseCamera(), or copied from one that was. Once all copies of a specific CameraPublisher go out of scope, any subscriber callbacks associated with that handle will stop being called. Once all CameraPublisher for a given base topic go out of scope the topic (and all subtopics) will be unadvertised.
