Unmanned aerial vehicle voice control method and system

Abstract

The invention discloses an unmanned aerial vehicle voice control method and system, and relates to the technical field of unmanned aerial vehicle control, and the method comprises the steps: S1, collecting real-time voice data of a user, and carrying out the preprocessing of the real-time voice data to obtain a bone conduction vibration signal and an air conduction vibration signal; s2, performing bimodal voiceprint authentication to obtain a voiceprint authentication result, and confirming that real-time voice data is from a user; s3, performing analysis content analysis on the de-noised human voice time-frequency spectrum data to obtain an output instruction text, and generating an intention classification label unmanned aerial vehicle instruction entity label set; s4, based on the real-time environment of the unmanned aerial vehicle, calculating and obtaining a safety potential field by combining the intention classification label unmanned aerial vehicle instruction entity label set; and S5, threshold judgment is carried out based on the safety potential field, and a control instruction is sent to an unmanned aerial vehicle flight controller.
