Abstract. The control system of an unmanned aerial vehicle (UAV) such as a quadrocopter is considered that allows solving problems of identification of a mobile object and tracking it when driving on a predetermined route in an emergency. For recognition of objects, the system uses sensors built into the quadrocopter and an on-board video camera as the basis of technical vision. An algorithm for identifying the object on the image obtained from the front camera of the ArDrone quadrocopter is proposed. Based on the analysis performed, the Viola-Jones method is used in the further work; it exploits the principle of contrasting sections of the shape depending on the object. The use of the proposed algorithm allows to ensure the movement of the UAV along a given trajectory, to search for a given object and, if detected, to monitor it or send information to the base.  

Keywords: quadrocopter, trajectory control, UAVs, tracking, mobile unit, machine vision, rescue operations
