摘要:
手机导航以其便捷和廉价得到广泛应用,而其运动模态对导航精度有较大影响. 基于手机内置IMU的量测信息,研究了一种运动模态判别方法. 该方法根据人体步态相位检测法和IMU中三轴加速度计和三轴陀螺仪的六维量测信息,选择合适参数,通过对试验采样数据的处理设定阈值和辨识窗口,确定实际应用算法流程. 试验结果表明,该方法实时判别手机运动模态的延时小,且在相应运动模态内的判别准确率达到100%,为后续导航算法的使用时机与过程提供了有效判断依据.
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.
