ABSTRACT:
A collision avoidance ability for UAV (42) during its non-VFR pre-programmed autonomous flight is achieved by using a forward-looking TV camera (20) which senses visual obstacles in direction of flight. The UAV is equipped with an autopilot which is able of maneuvering and incorporated in a form of flight/mission computer's (10) program. Image processor (18) locks and tracks obstacles in the camera's field of view in real time. It provides the autopilot with information about level of threat and generates appropriate commands. Being warned by the TV camera (20), flight/mission computer (10) initiates appropriate maneuver, in order to avoid possible collision. After that, it returns to interrupted pre-programmed flight. Two forward-looking TV cameras are used to measure a distance between the UAV (42) and the obstacle considering that the level of threat is higher if this distance is less.
