摘要(Abstract)：

针对室内活动场景下，额外布设定位基站成本较高，应用范围有限，基于手机的室内高精度位置服务需求难以满足的问题。考虑到Wi-Fi在全球网络中的广泛部署及智能手机内置多种运动传感器，本文实现了基于Wi-Fi RTT测距信息和手机内置多传感器的实时室内定位方法，并在室内进行静态和动态定位实验。实验结果表明：该算法无论是定位精度还是定位准度都优于仅依赖于Wi-Fi RTT测距信息的Wi-Fi RTT LS算法和Wi-Fi RTT UKF算法，平均定位误差为1.16 m,最大定位误差为2.14 m。

关键词(KeyWords)： Wi-Fi往返时间;室内定位;智能手机;测距
