calibration parameters.
image_transport should always be used to subscribe to and publish images. It
provides transparent support for transporting images in low-bandwidth
compressed formats. Examples (provided by separate plugin packages) include
JPEG/PNG compression and Theora streaming video.
polled_camera contains a service and C++ helper classes for implementing a
polled camera driver node and requesting images from it. The package is
currently for internal use as the API is still under development.
