视觉辅助的运动声源定位方法
A Computer Vision Aided Method for Localizing Moving Sound Source
摘要
Abstract
When using the sound source location algorithm to locate the moving sound source,the location is often in-accurate because of the velocity fluctuation of the actual moving object,which reduces the function of the algorithm.To solve this problem,this paper proposed a method of locating moving sound source based on visual aid.Firstly,the key points in the image were detected by the scale invariant feature transform algorithm,and the pixel displacement of key points be-tween adjacent frames was determined.Then the velocity curve of the moving sound source was fitted according to the cam-era frame rate.Then the velocity curve after Kalman filtering was substituted into the sound source localization algorithm to generate the sound pressure cloud map.Finally,the cloud map was fused with the shot image to realize the location of the moving sound source.The experimental results show that the proposed method can accurately estimate the velocity of the moving sound source in real time,and introducing the fitting velocity curve into the sound source location algorithm can ef-fectively locate the moving sound source.关键词
