铁路沿线地物参数化三维建模方法研究
Research on 3D Parametric Modeling of Objects along Railways
摘要
Abstract
A method of parametric modeling by using DOM and LiDAR point cloud date was presented in this pa-per. The features of ground object model are analysed with DOM and the partial feature point coordinates of ground object are obtained with LiDAR point cloud. Besides, a specific method of triangle network connection is adopted in it to build 3D ground object model, and finally maps the model to display. The proposed method in this paper is not only efficient and fast, but its high degree of automation also can meet the requirements of exhibition of the railway 3D GIS. Meanwhile, based on the model built by point cloud data, huge workload of placing ground object model can be reduced during the latter period of inputting 3D terrain.关键词
