Abstract:
Mobile navigation is widely used for its convenience and low cost,but its motion mode has a great influence on navigation accuracy. A distinguishing method for motion mode is studied basing on measurement information of mobile phone’s built-in IMU. The method selects appropriate parameters according to human gait phase detection and the six dimensional measurement information from three-axis accelerometer and three-axis gyroscope in IMU. It also sets threshold and identification window on the basis of tested sampling data and determines the algorithm flowchart for practical application. Experimental results show that,the method has a smaller time-delay and its accuracy rate reaches 100%,which provides a basis for the use of the following navigation algorithm.
