摘要/Abstract

摘要： 针对室内定位存在单一定位精度低，以及组合定位成本高、不易实现的问题，提出了一种利用环境光修正行人航迹推算（PDR）的方法。该方法利用智能手机采集的加速度、陀螺仪和磁力计数据实现PDR位置估计；同时利用手机的光线传感器实时获取所在位置的环境光强度信息，基于采集的室内环境光强度信息修正PDR轨迹中产生的累计误差。经试验数据分析，该方法可以有效地解决PDR轨迹中产生的累计误差，可为大型超市、地下停车场、隧道、矿井等室内光照强度较为稳定的区域提供定位技术帮助。

关键词: 室内定位, PDR, 环境光, 位置估计, 累计误差

Abstract: Aiming at the problem of low positioning accuracy, high combination positioning cost and difficulty to realize in indoor positioning, a method of correcting pedestrian track calculation (PDR) using ambient light assistance is proposed. This method uses the acceleration, gyroscope and magnetometer datacollected by the smartphone to realize the PDR position estimation. At the same time, the light intensity sensor of the mobile phone is used to obtain the ambient light intensity information of the location in real time, the collected indoor ambient light intensity information is used to correct the cumulative error generated in the PDR trajectory. After the experimental data analysis, this method can effectively solve the cumulative error produced in the PDR trajectory, it can provide positioning technology for large supermarkets, underground parking lots, tunnels, mines and other areas with stable indoor illumination intensity.

Key words: indoor positioning, PDR, ambient light, location estirnation, cumulative error
