利用第二次土地调查DOM和DEM数据进行送电工程勘测设计

Survey and Design of Transmission Line Engineering by Using DOM and DEM Data of the Second Land Surveying

本文主要是依据已有山东省第二次土地调查DOM和DEM数据,通过核线共线方程原理恢复生成大场景三维立体模型,然后进行架空送电线路路径优选、测量平断面图及外业采集交叉跨越和断面数据精确拟合等数据处理、进行三维漫游等,主要研究将测量标准4D数据应用到中架空送电工程勘测设计全过程中,本文通过工程实际应用,提出了应用方法及作业注意事项等。

In this paper, using the principle of epipolar colinearity equation, the large scene 3D stereo＇model were generated by the existing DOM and DEM data of the second time land survey in Shandong province. The realized functions are as follows： paths optimization of overhead transmission line, plane cross section survey, field data acquisition crossing, profile data accurate fitting, 3D roaming and so on. The main study of this paper is applying 4D standard data in the whole process of overhead transmission engineering surveying and designing. Finally, applying methods and operation attentions based on the practical engineering application.
