融合多源信息的室内定位App的设计与实现

Design and Implementation of Multi-source Information Fusion Indoor Positioning App

基于多源信息融合的室内定位是当前室内定位发展的趋势。本文以智能手机无线定位和惯性传感器定位为研究对象,在研究算法分别提高两者传统定位方法的精度的基础上,基于安卓智能手机开发室内定位App,使用自适应抗差滤波算法实现了两者的组合定位,能够弥补使用单一方式进行室内定位存在的缺陷,得到更高精度的室内定位成果。最后在上海市测绘院二楼进行实验分析,验证了多源信息融合室内定位的有效性。

Indoor positioning based on multi-source information fusion is the current trend of indoor positioning.In this paper,positioning by smart phone wireless and inertial sensor are taken as the research objects.On the basis of improving the accuracy of traditional positioning methods,the indoor positioning App is developed based on Android smart phone.The combination positioning of the two is realized by using adaptive robust filtering algorithm,which can make up for the defects of using a single way of indoor positioning and obtain more accurate indoor positioning results.Finally,the experimental analysis on the second floor of the Shanghai Institute of Surveying and MApping verifies the effectiveness of multi-source information fusion indoor positioning.
