【摘要】 在分析误差来源和城市道路现状的基础上,借助线性回归方程,提出了误差三角形的模型,采用整体平移匹配方法削弱了系统误差;对大量GPS点的坐标和航向进行了分析,提出了双向车道与GPS航向角间的关系模型,优化了匹配算法,削弱了GPS的随机误差,提高了地图匹配的速度和精度。更多还原

【Abstract】 It proposes the model of error triangle with the aid of the linear regression equations on the analysis of the error sources and the status of city roads, uses the whole parallel moving matching method to weaken the system error; It analyzes coordinate and heading angle of thousands of GPS positioning points, puts forward the model of the relationship between the bidirectional traffic lane and the GPS heading angle, that optimizes the matching algorithm, weakens the GPS random error and improves the speed and accuracy of the map matching.更多还原
