摘要
为了实现较高精度的室内定位功能,利用Wi-Fi技术设计并搭建了室内定位系统,并提出一种定位组合算法。选择以Android系统为载体的移动定位终端,应用Eclipse开发工具自主开发手机端功能模块。除此之外,在PC端应用Mysql和QT Creator软件创建并设计定位指纹信息库及服务器端窗口,以完善室内定位系统。着重研究并设计了室内定位组合算法:包括位置指纹投票法与基于损耗测距模型的结合,NN匹配算法的应用等,成功获得了较高的定位精度。通过进行系统的实地测试与定位结果分析,验证了组合算法的有效性。
In order to realize the indoor positioning function with high accuracy,this paper used Wi-Fi technology to build the indoor Wi-Fi positioning system, designed the combined location algorithm independently. This paper chose a mobile positioning terminal with Android system as the carrier,used the Eclipse development tools to design the functional modules at the cellphone terminal independently. In addition,the paper used the MySQL software to create a location fingerprint information database and designed the server-side window interface by QT Creator soft-ware ,so as to improve the indoor positioning system. This paper focused on the design of the integrated indoor posi-tioning algorithm,which included the combination of the Fingerprint Voting Method,the Loss Ranging Model and the application of NN matching algorithm, etc. ,successfully obtained high positioning accuracy. Finally,by testing the function of the entire positioning system and analyzing the result,the effectiveness of the combined location al-gorithm was verified.
