Abstract

一种输电线路三维点云数据处理及交跨物物获取方法,根据地形地物在所述三维点云数据中的实际信息建立地形地物信息数据库;利用三维激光扫描获取原始三维点云数据;获取地物。本发明在不改变原始点云数据原有基础上,不进行任何建模渲染处理,不改变任意一点的空间信息,准确获取了各种地物的点云数据,根据设计规程具体要求,形成适用于高压输电线路三维设计的地形图,这在国际上是首次实现,是线路设计技术领域的突破。
Provided is a method for point cloud data processing and crossover object obtaining of a transmission line. A terrain and ground object information database is established according to actual information of terrain and ground objects in three-dimensional point cloud data; original three-dimensional point cloud data is obtained by utilizing three-dimensional laser scanning; and the ground objects are obtained. On the original basis of not changing the original point cloud data, no modeling rendering processing is performed, spatial information at any point is not changed, he point cloud data of the various ground objects is obtained accurately; and according to concrete requirements of design disciplines, a topographic map suitable for three-dimensional design of a high-voltage transmission line is formed, which is achieved internationally for the first time and is a breakthrough in the technical field of track design.
