一种基于路网曲线特征和惯导测量数据的辅助导航定位方法

An Assistant Navigation Positioning Algorithm Based on the Road Curve Feature and Inertial Navigation Data

不同于已有的辅助导航定位方法,提出了基于路网曲线特征和惯导测量数据的导航定位方法,即通过对道路网和行驶惯导轨迹数据利用曲线拟合和特征提取的方法进行处理,得到能够反映出目标实际运动状态和位置情况的特征点和线,并将它们进行匹配,以达到修正导航位置的目的。

Different from the existing assistant navigation method, a navigation positioning algorithm based on the road curve feature and inertial navigation data was proposed. Firstly, the curve fitting and feature extraction method was used to process the road network and driving track data. Secondly, the feature points and lines were picked up which reflected the actual movement and position. Finally, the road matching was established and the purpose of modified navigation positioning was achieved.
