SYSTEMS AND METHODS FOR RELIABLE RELATIVE NAVIGATION AND AUTONOMOUS FOLLOWING BETWEEN UNMANNED AERIAL VEHICLE AND A TARGET OBJECT
First Claim
1. A method for navigating an airborne device relative to a target, comprising:
- detecting, at an signal detector associated with the airborne device, at least one signal generated by a signal emitter associated with the target;
correlating, by a processor associated with the airborne device, the detected signal with a previously-detected signal;
determining, by the processor based on the comparison, a change in location of at least one of the airborne device or the target; and
adjusting a position of the airborne device based, at least in part, on the determined change in location.

Abstract
A method for navigating an airborne device relative to a target comprises detecting, at an optical detector on the airborne device, an optical signal generated by one or more LEDs on the target. The method also comprises comparing, by a processor on the airborne device, the detected optical signal with a previously-detected optical signal. The method further comprises determining, by the processor based on the comparison, a change in location of at least one of the airborne device or the target. The method also comprises adjusting a position of the airborne device based on the determined change in location. The method also comprises predicting, by the processor, a movement of the target based on information indicative of at least one of a position, a rotation, an orientation, an acceleration, a velocity, or an altitude of the target, wherein the position of the airborne device is adjusted based on the predicted movement of the target. The method also comprises detecting an obstacle in a flight path associated with the airborne device and adjusting a position of the airborne device is further based, at least in part, on detected obstacle information.
