建筑立面测绘坐标转换程序研究与实现

Research and Implementation of Coordinate Conversion Program for Measuring Building Facade

为完成建筑立面测绘,利用免棱镜全站仪测得建筑物外立面各个特征点的三维坐标,并转换到统一的坐标系统进行立面图绘制是十分必要的。本文结合工程实例研究立面图与平面图之间的坐标转换关系,基于ExcelVBA模式开发立面测绘坐标转换程序,将全站仪原始数据直接导入Excel,再将坐标转换到外立面的主墙体上,并重点探讨立面测绘方法及立面图绘制的关键技术。实践结果表明,该立面测绘坐标转换程序可以满足建筑立面测绘的需要。

In order to finish the building elevation surveying,it is necessary to use prism-free total station to measure the three-dimensional coordinates of each characteristic point of the building elevation,and convert to a unified coordinate system for the elevation mapping.This paper studies the coordinate conversion relationship between elevation map and plan map with an engineering example,and develops a coordinate conversion program for elevation surveying based on Excel VBA model.The original data of total station is directly imported into the Excel,then the coordinates are transferred to the main wall of the exterior facade,and the key techniques of the elevation surveying and drawing are discussed.The practical results show that the coordinate conversion program can meet the needs of building elevation surveying and Mapping.
