摘要:

根据分段、特征提取等地图匹配关键技术探讨了地图匹配的一般原理。提出了基于航向信息的INU(Inertial Navigation Unit) /MM(Map Matching)算法、以及基于卡尔曼滤波的GPS/INU/MM组合导航算法,仿真结果表明上述方法是行之有效的。

关键词: 地图匹配, 组合导航, GPS, INU, 卡尔曼滤波

Abstract:

General principles on Map Matching are investigated according to segmentation and feature extraction, and an algorithm considering azimuth of vehicle for INU/MM system and a Kalman filter for GPS/INU/MM integrated system is proposed in the paper. Finally, a simulation example demonstrates the effectiveness of the proposed algorithm for the requirement of Vehicle Location and Navigation.

Key words: map matching, integrated navigation, GPS, INU, Kalman filter
