Cascade recognition for personal tracking via unmanned aerial vehicle (UAV)
First Claim
1. An unmanned aircraft system (UAS), comprising:
- an airframe;
a propulsion system coupled to the airframe;
at least one camera attached to the airframe, the camera configured to;
capture at least one first image sequence associated with a subject and a gesture performed by the subject;
andcapture at least one second image sequence, the first image sequence and the second image sequence associated with one or more of a heading of the UAS, a position of the UAS relative to the subject, and an orientation of the UAS;
anda control system coupled to the propulsion system and to the at least one camera, the control system comprising one or more processors and configured to;
associate the first image sequence with the subject and the gesture;
associate the gesture with at least one command executable by one or more of the control system and the propulsion system;
store the at least one first image sequence to a memory coupled to the control system;
identify one or more of the subject and the gesture within the second image sequence;
andexecute the at least one command associated with the identified gesture via one or more of the control system and the propulsion system.

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.
