| 摘 要： | 利用机载激光扫描数据的离散道路带状数据点云恢复公路平面线形,其效果的优劣很大程度上取决于公路中轴点列的获取。采用定步长径向搜索方法,算法简单快速,运算效率高;采用三次B样条曲线拟合及线形恢复能满足公路改(扩)建的要求。实验表明,基于道路数据点云的公路平面线形恢复方法研究,为机载激光扫描技术在公路中的应用提供一种可供借鉴的方法。

| Abstract: | The effect of highway alignment recovery from LIDAR data depends largely on extraction of road axis points.A step radial search method discussed in this paper is proved to be simple and compute fast.Also the three B-spline curve fitting used in highway linear can meet the requirements of road reconstructed.Experiments show that the study of highway alignment recovery based on road data point cloud provided a way for applying airborne LIDAR technology to highway. |
