摘要
输电线路施工设计对通道内地物高程精度要求较高,在初设阶段传统的摄影测量无法满足三维设计对交跨的要求。以江苏某500 k V输电线路工程为实例,介绍了采用地面架站式激光雷达对线路沿线三处重要交跨进行三维激光扫描,并通过对点云的处理、建模,总结分析了激光雷达技术在线路交跨测量及输电三维设计等方面的应用。
The construction design of transmission lines requires high accuracy of elevation of objects in the channel,and the traditional photogrammetry in the preliminary design stage can not meet the requirements of three-dimensional design for cross-over. Taking a 500 k V transmission line project in Jiangsu province as an example,this article introduces the three-dimensional laser scanning of three important intersections in the line by using ground-based station LiDAR,and summarizes and analyses the application of lidar technology in line intersection measurement and transmission three-dimensional design by processing and modeling point clouds.
