摘要:

传统室内人员行为检测方法检测准确率较低,稳定性较差。为此,提出一种基于信道状态信息(CSI)的室内人员行为检测方法。采集 CSI原始数据包后使用Kalman滤波算法对其进行过滤,运用SVM算法对过滤后的数据作分类处理并建立指纹库。同时,利用PSO算法修正 SVM中的参数,然后采用SVM算法处理从真实环境内实时采集到的数据后,将该实时数据与指纹库的数据一一匹配。在此基础上,实现室 内人员的行为检测。实验结果表明,相比LIFS、FIMD方法,该方法可以更精细地识别室内人员的动作行为,且稳定性更高。

Abstract:

The traditional indoor personnel behavior detection method has low accuracy and poor stability.To solve this problem,an indoor personnel behavior detection method based on Channel State Information(CSI) is proposed.After collecting the CSI raw data package,it uses Kalman filtering algorithm to filter it,and uses the SVM algorithm to classify the filtered data,and then builds the fingerprint database.At the same time,the PSO algorithm is used to modify the parameters of the SVM,then the real time data collected from the real environment is processed by SVM,and the real-time data is matched with the data of the fingerprint library.On this basis,indoor personnel behavior detection is realized.Experimental results show that,compared with LIFS and FIMD method,this method can identify the behavior of indoor personnel more accurately and has higher stability.
