The system of video-based navigation for unmanned aerial vehicles. Its application for navigation and airborne terrestrial robots control.
Nowadays availability of the GPS signal is necessary condition for UAVs operating. Signal failure or its deliberate suppression makes it impossible to determine the coordinates accurately, and, as a result, to accomplish a desired track flight. The use of inertial navigation systems also doesn’t solve the problem completely: solutions existing at the market (GPS/INS) are not autonomous, precision products are costly and are not noise-proof. The project suggests to solve the problem of ensuring the autonomy of UAVs in the absence of satellite navigation signals on the basis of alternative data sources: image information from onboard daytime and infra-red photo/video cameras and digital terrain data. We develop also simplified commercial video navigator for airborne unmanned ground vehicles (robot-lawnmower) control
