Abstract:
1. An electro-optical system capable of being embarked aboard a mobile unit, for determining optical flow generated by obstacles in relative motion with respect to the mobile unit characterized in that it comprises radiation emitter means ( 5 ), receiver means ( 1 ) for converting the radiation reflected by objects into electrical signals and means ( 8 ) for processing the signals generated by said receiver means ( 1 ), in which said receiver means ( 1 ) comprise at least a vision sensor with receiver matrix configuration and in which said emitter means ( 5 , 6 ) conform the radiation beam in such a way that the radiation reflected by objects and collected by the receiver means impacts at least a part of the receiver matrix configuration, and in which said processing means compute the optical flow only on the elements of the receiver matrix configuration that are impacted by the radiation.
