Think of a camera as a means of adding information to a database about space.
Bristol Researchers' Camera Knows Exactly Where It Is
University of Bristol News (U.K.)
A camera developed by researchers at the U.K.'s University of Bristol can construct a pictorial map to ascertain its current location. The camera employs a processing-on-sensor Pixel Processor Array (PPA) that can recognize objects at thousands of frames per second, to generate and use maps at the time of image capture, in conjunction with an on-board mapping algorithm. When presented with a new image, the algorithm determines whether it is sufficiently different to previously observed images, and stores or discards data based on that assessment. As the PPA device is moved around by a person or robot, for example, it compiles a visual catalog of views that can be used to match any new image in localization mode. The PPA does not send out images, which boosts the system's energy efficiency and privacy. ... '
