基于行人运动模态辨识的室内外无缝导航航向算法研究
Research on Indoor and Outdoor Seamless Navigation Heading Algorithm Based on Pedestrian Modal Identification
摘要
Abstract
Nowadays,heading algorithm in pedestrian navigation is mostly based on the fixed mode of navigation sen-sor on the pedestrian body,or relies on other auxiliary radio frequency information,which greatly reduces the porta-bility of sensors. Hence,based on the sensitivity of the gyroscope to the low frequency noise and the stability of the accelerometer,this paper puts forward one solution to determine the steady-state and non-steady state of the hand held mobile based on the modal identification and proposes complementary filter to achieve optimal attitude based on time domain. This paper uses modified complementary filter to weaken the interference caused by pedestrian movement and improves the accuracy of the carrier attitude measurement. In addition,the adaptive kalman filter al-gorithm is designed by using the magnetic sensor calibration data to restrain the divergence of heading angle error. The test results show that this algorithm can ensure that the accuracy of heading angle measurement in indoor and outdoor pedestrians can be improved by 80% and greatly improve the adaptability and portability of sensors simulta-neously,which meets the demand of practical engineering.关键词
