摘要 利用感知的背景声进行定位是室内定位的一种新型解决方案。拟在无需其他基础设施的条件下,利用智能手机麦克风被动感知室内背景声,实现房间级的定位。采用有监督的学习方式,对房间背景声进行功率第五百分位特征提取,并以此为训练集样本。分别使用k最近邻(KNN)、BP神经网络以及径向基神经网络(RBF)训练算法训练出房间背景声定位模型。以房间识别率与定位耗时为指标,通过线下训练、线上测试的方式对所提方案进行可靠性与有效性的验证。实验结果表明,RBF神经网络房间识别率在75%以上且运行时间较短。 The positioning using the perceived background sound is a new solution for indoor positioning.This paper intends to use the smart phone microphone passive perception of the indoor background sound,room-level positioning without additional infrastructure.In this paper,the supervised learning mode is adopted to extract the fifth percentile power of the background of the room,which is used as a training set sample. The background sound localization model of the room is trained by k nearest neighbors( KNN),BP neural network and radial basis neural network( RBF) training algorithm respectively.By using the room recognition rate and positioning time as an indicator,the reliability and availability of the proposed solution are verified through the offline training,online testing. The experimental results show that the recognition rate of RBF neural network is above 75% and the running time is short.
