输电线路大跨越段导线空间距离测量新方法

摘要

This article is mainly studying for the spatial distance measurement of the power transmission line about large cross section , propose an new way as intersection and height measurement method and make strict theoretical accuracy of estimation. Research and development the professional computer programs for measurement, Has satisfied the precision request through the project practice confirmation, the project practice verification to meet the requirement of accuracy, have solved the technical difficult problem about the power transmission line 3-D space distance in the terrain difficult area such as the entire station meter laser range finding or conventional methods and so on ground three dimensional laser scanning method is unable to survey the power transmission line 3-D space distance.%本文主要针对送电线路大跨越段导线空间距离测量开展研究,提出了交会及悬高测量法并严格进行了理论精度估算.编制了专用测量程序,通过工程实践验证满足精度要求,解决了全站仪激光测距法或地面三维激光扫描法等常规方法无法在地形困难地区进行导线空间距离测量的技术难题.
