摘　　要：道路线形参数计算对于公路现状调查、道路优化设计、道路信息管理、安全分析和建立公路的三维空间模型均具有重要意义。根据道路线形的特点,利用基于Hough变换的直线和圆曲线提取算法对数据进行分组,然后利用稳健估计对数据进行迭代平差,计算出道路各段线形参数,从而实现道路线形识别的目的。算法由Visual C++语言实现,在实践中证明是很有效的。In the investigation of China present road state, the computing of road line eters are very important. After the positions of road centerlines are acquired, accordin type paramto road line types, the first step is grouping to coordinates data of road centerlines by extracting straight lines algorithm and detecting circle algorithm based on Rough Transform, then the second step is adjusting by method for Selecting Weight Iteration with robust estimation. So the goal of road line identification is attained after the road line type parameters have been known. This method of road line type identification has proved its availability by Visual C＋＋ programming finally.
