Active vision

Active vision

An area of computer vision is active vision, sometimes also called "active computer vision". An active vision system is one that can manipulate the viewpoint of the camera(s) in order to investigate the environment and get better information from it.

Examples of active vision systems usually involve a robot mounted camera [cite journal

Applications include automatic surveillance, SLAM, route planning [ [http://www.surrey.ac.uk/eng/research/mechatronics/robots/Activities/ActiveVision/activevis.html http://www.surrey.ac.uk/eng/research/mechatronics/robots/Activities/ActiveVision/activevis.html] ] , etc. In the DARPA Grand Challenge most of the teams used LIDAR combined with active vision systemsto guide driverless vehicles across an off road course.
