| 摘 要： | 针对WiFi指纹室内定位中AP(access point)选取算法问题,提出了一种基于WiFi信号的整体区间重叠度(overall interval overlap degree,OAIOD)AP选取的优化算法,给出了算法的流程和整体区间重叠度计算方法。通过实验并与区间重叠度、信息增益、信息增益率、互信息等多种AP选取算法相比,结果表明:该算法定位精度较高,可靠性和稳定较好,增强了AP对指纹点的识别能力,又减少了指纹点中AP之间的关联性。

| Abstract: | Aiming at the problem of AP selection algorithm in WiFi fingerprint indoor positioning,this paper proposes an optimization algorithm based on WiFi signal for Overall Interval Overlap Degree(OAIOD)AP selection,and gives the flow and overall of the algorithm.Interval overlap calculation method.Compared with various AP selection algorithms such as interval overlap(IOD),information gain,information gain rate and mutual information,the results show that the algorithm has higher positioning accuracy,better reliability and stability,and enhanced AP pair.The ability to identify fingerprint points reduces the correlation between APs in the fingerprint points. |
