Systems and methods for unmanned aerial vehicle object avoidance
First Claim
1. A method of monitoring airspace at least partially surrounding an unmanned aerial vehicle (UAV), the method comprising:
- receiving one or more signals representative of an environment extending from the UAV;
analyzing the one or more signals to determine a presence of an object;
identifying an object type of the object based at least in part on the one or more signals;
determining one or more operating characteristics of the object based at least in part on the one or more signals; and
determining a trajectory envelope of the object based at least in part on the object type and the one or more operating characteristics of the object, wherein the trajectory envelope includes at least a probability of possible future locations of the object during a predetermined period of time.

Abstract
This disclosure is directed to a detection and avoidance apparatus for an unmanned aerial vehicle (“UAV”) and systems, devices, and techniques pertaining to automated object detection and avoidance during UAV flight. The system may detect objects within the UAV'"'"'s airspace through acoustic, visual, infrared, multispectral, hyperspectral, or object detectable signal emitted or reflected from an object. The system may identify the source of the object detectable signal by comparing features of the received signal with known sources signals in a database. The features may include, for example, an acoustic signature emitted or reflected by the object. Furthermore, a trajectory envelope for the object may be determined based on characteristic performance parameters for the object such as cursing speed, maneuverability, etc. The UAV may determine an optimized flight plan based on the trajectory envelopes of detected objects within the UAV'"'"'s airspace.

8. An unmanned aerial vehicle (UAV), comprising:
-
one or more processors; memory to store computer-readable instructions; one or more sensors generating signals representative of at least a portion of an airspace about the UAV; and a flight management component stored within the memory that, when executed, causes the one or more processors to process at least some of the signals and to perform acts comprising; detecting a presence of an object in the at least a portion of the airspace about the UAV based at least in part on the at least some of the signals; determining, based at least in part on the at least some of the signals, at least an object type of the object and an operating characteristic of the object; and determining a trajectory envelope of the object based at least in part on the object type of the object and the operating characteristic of the object, wherein the trajectory envelope includes at least a probability of possible future locations of the object. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
one or more processors; and memory to store computer readable instructions that when executed, causes the one or more processors to perform acts to; analyze signals generated by one or more sensors onboard an unmanned aerial vehicle (UAV) to determine a presence of an object in an airspace around the UAV; determine an object type of the object in response to determining the presence of the object in the airspace around the UAV; and determine a trajectory envelope of the object based at least in part on the object type of the object, wherein the trajectory envelope includes at least a probability of potential changes of a location of the object over a period of time. - View Dependent Claims (16, 17, 18, 19, 20)
