室内定位技术对基于室内位置信息的服务和测量至关重要。基于加速度、陀螺仪和磁强计等传感器，提出一种适用于室内行走的定位方法，该定位方法利用传感信号和滤波算法得出行走步数、步长及方向，并采用轨迹匹配算法对轨迹数据进行修正得出优化轨迹。通过实地测试表明：该方法能准确地还原行走轨迹，可应用于实际室内场景。

Indoor positioning technology is important for services and measurement based on indoor location information. Based on sensors such as accelerometer,gyroscope and magnetometer,a positioning method suitable for indoor walking is proposed,this positioning method obtains numbers of walking steps,step length and direction according to sensing signals and filtering algorithms,and using trajectory matching algorithm to correct trajectory data in order to obtain optimized trajecttory. According to positioning test in the actual scene shows that this method can accurately restore the walking trajectory and can be applied to practical interior scenes.
