基于人体步态运动的行人航位推算（PDR）是一种很有前途的室内定位服务解决方案，它利用多个传感器独立确定用户的相对位置。大多数现有的PDR方法假设所有传感器都安装在用户行走时身体上的固定位置。然而，对于用户来说，将他/她的移动的电话或附加传感器模块安装在他/她的身体上的特定位置（诸如躯干）是不方便的。在本文中，我们提出了一种新的PDR方法和原型系统适用于室内导航系统的移动的手机。我们的方法确定用户的相对位置，即使传感器相对于用户的方向是不给定的，从时刻到时刻的变化。因此，用户不必将包含传感器的移动的电话安装在身体上，并且可以在行走时以自然的方式携带它，例如，同时摆动手臂。详细的算法，实施和实验评估结果。
Pedestrian dead reckoning (PDR) based on human gait locomotion is a promising solution for indoor location services, which independently determine the relative position of the user using multiple sensors. Most existing PDR methods assume that all sensors are mounted in a fixed position on the user's body while walking. However, it is inconvenient for a user to mount his/her mobile phone or additional sensor modules in a specific position on his/her body such as the torso. In this paper, we propose a new PDR method and a prototype system suitable for indoor navigation systems on a mobile phone. Our method determines the user's relative position even if the sensors orientation relative to the user is not given and changes from moment to moment. Therefore, the user does not have to mount the mobile phone containing sensors on the body and can carry it in a natural way while walking, e.g., while swinging the arms. Detailed algorithms, implementation and experimental evaluation results are presented.
