Simulation Research on Road Feature Point Extraction Algorithm Based on Infinite-Circle Approximation Curve
摘要
Abstract
High-precision electronic map is usually composed of compressed road information obtained from vehicle GPS (Global Positioning System) and appropriate road feature points,which can provide reference for the vehicle integrated navigation system (INS/DR/MM).According to the characteristics of the trajectory of the carrier which can be regarded as the circular curve,road feature point extraction algorithm was studied based on the method of infinite-circle approximation curve.The curvature radius was calculated by the curvature of the data point to determine the step size on the trajectory circle and extract the road features.The experimental results show that the proposed algorithm can reduce the calculation amount,improve the efficiency of data compressing,and ensure the road in the map not distorted.关键词
