Abstract
Systems and methods for tracking a subject using an unmanned aerial vehicle (UAV) are disclosed. The UAV includes an onboard camera to capture/stream multiple images. The camera captures reference images of a subject to be stored in memory; the reference images may portray gestures performed by the subject and associated with specific command procedures. The camera may capture subsequent images portraying the subject; the control system may, based on cascade recognition, identify the subject and a stored gesture to a determined confidence level. Once the subject and gesture are positively identified, the control system and/or propulsion system of the UAV may execute the associated command procedures to change the position, velocity, or heading of the UAV.
