Detailed Description

A class for grabing images from a "OpenCV"-compatible camera, or from an AVI video file.

See the constructor for the options when opening the camera.

Unless input from AVI files is required, it is recommended to use the more generic class mrpt::hwdrivers::CCameraSensor.

Note:

This class is only available when compiling MRPT with the flag "MRPT_HAS_OPENCV" defined.

Some code is based on the class CaptureCamera from the Orocos project.
