US 2024/0201696 A1 · AUTONOMOUS DETECT AND AVOID FROM SPEECH RECOGNITION AND ANALYSIS

Abstract

A technique for detecting and avoiding obstacles by an unmanned aerial vehicle (UAV) includes: querying a knowledge graph having information related to a dynamic obstacle that may be in proximity to the UAV when traveling along a planned route; comparing the location of the dynamic obstacle to the UAV to detect conflicts; and in response to detecting a conflict, performing an action to avoid conflict with the dynamic obstacle. The knowledge graph can be updated by receiving a VHF radio signal containing the information related to the dynamic obstacle in the audible speech format; translating the audible speech format to a text format using speech recognition; analyzing the text format for relevant information related to the dynamic obstacle; comparing the relevant information related to the dynamic obstacle of the text format to the knowledge graph to detect changes; and updating the knowledge graph.

Dependent claims

A non-transitory computer-readable medium having logic stored thereon that, in response to execution by one or more processors of an unmanned aerial vehicle (UAV), causes the UAV to perform actions comprising:

traveling along a planned route of the UAV;
querying a knowledge graph having information related to a dynamic obstacle that may be in proximity to the UAV when traveling along the planned route, wherein the knowledge graph includes information related to the dynamic obstacle received as a wireless radio signal in an audible speech format;
comparing a location of the dynamic obstacle to the UAV when traveling along the planned route to detect conflicts;
and
in response to detecting a conflict between the dynamic obstacle and the UAV when traveling along the planned route, performing an action by the UAV to avoid the conflict with the dynamic obstacle.
