Garcia-Pardo, Pedro J.; Sukhatme, Gaurav S.; Montgomery, James F. Towards vision-based safe landing for an autonomous helicopter. (English) Zbl 1017.68133 Robot. Auton. Syst. 38, No. 1, 19-29 (2002). Summary: Autonomous landing is a challenging problem for aerial robots. An autonomous landing manoeuver depends largely on two capabilities: the decision of where to land and the generation of control signals to guide the vehicle to a safe landing. We focus on the first capability here by presenting a strategy and an underlying fast algorithm as the computer vision basis to make a safe landing decision. The experimental results obtained from real test flights on a helicopter testbed demonstrate the robustness of the approach under widely different light, altitude and background texture conditions, as well as its feasibility for limited-performance embedded computers.
