Abstract

The invention discloses a user identification method and device for an unmanned aerial vehicle charging cabinet and the charging cabinet. The method comprises the steps of collecting audio and video data of a to-be-identified user; extracting a sound signal from the audio and video data, processing the sound signal to form a voice vector, and performing voice recognition according to the voice vector; extracting image data from the audio and video data, extracting dynamic features, static features and key point features of a human face according to the image data, and obtaining mixed features based on a singular value decomposition method; performing face recognition according to the mixed features; performing user authentication according to the voice recognition result and the face recognition result; the method can greatly shorten the recognition time, improve the recognition accuracy and reduce the complexity of the algorithm.

Description

technical field [0001] The invention relates to the technical field of intelligent charging for unmanned aerial vehicles, in particular to a user identification method and device for a charging cabinet for unmanned aerial vehicles and a charging cabinet. Background technique [0002] At present, drones have been widely used in many fields. The inspection of power lines is one of the important application fields of drones. Multiple drones are needed for inspection in an area. With the increase of drones, It makes its management more and more difficult. Therefore, the UAV charging cabinet emerges as the times require. For example, the patent document CN214303105U discloses an intelligently managed UAV warehouse. The main body of the UAV warehouse is provided with a fuselage storage cabinet and Lithium battery charging cabinet, the fuselage storage cabinet is equipped with multiple separate fuselage compartments, and the fuselage compartments are all equipped with cabinet doors...
