Sound source positioning method and device and storage medium

Abstract

The invention relates to a sound source positioning method and device and a storage medium, and belongs to the technical field of computers. The method comprises the steps of determining a first coordinate system coordinate value of the sound source position of a target sound signal in a first coordinate system when the target sound signal is acquired, wherein the first coordinate system is established based on the position of an audio acquisition assembly; obtaining a coordinate conversion relationship; and converting the first coordinate system coordinate value into a second coordinate system by using the coordinate conversion relationship to obtain a second coordinate system coordinate value so as to trigger an image acquisition assembly to acquire an image of a sound source corresponding to the second coordinate system coordinate value, wherein the second coordinate system is established based on the positions of the audio acquisition assembly and the image acquisition assembly. The problem that the acquisition result is inaccurate when the sound source image is acquired by using the first coordinate system coordinate value can be solved; the second coordinate system is a coordinate system shared by the audio acquisition assembly and the image acquisition assembly, so that the accuracy of the acquisition result can be improved by acquiring the sound source image according to the second coordinate system coordinate value.

Description

technical field [0001] The present application relates to a sound source localization method, device and storage medium, and belongs to the technical field of computers. Background technique [0002] Honking of vehicles in urban areas will seriously disturb the people, so most areas stipulate that honking of vehicles in urban areas is prohibited. In order to ensure the monitoring of violating the whistle, it is necessary to locate the position of the whistle and transmit the position of the whistle to the license plate capture device. The license plate capture device captures the license plate number of the vehicle that violates the rules and whistles and stores it. [0003] Chinese patent 201710062470.4 discloses a car whistle law enforcement evidence collection system, which includes a whistle monitoring system and a high-definition camera capture system. The whistle monitoring system is used to collect sound signals and output whistle coordinates, and then send the whistl...
