摘要
立面图是城市建筑物外观装修和景观改造设计与施工中的重要依据。其投影面是与立面平行的铅垂面,但常见成图软件的投影面是水平面,因此无法直接用于立面图测绘。本文从立面测量的原理出发,介绍了基于全站仪和CASS成图软件的立面测量方法,阐述了立面测量坐标转换的方法,并对此方法做出了精度分析。
Elevation is an important basis for construction and reformation of buildings.One feature of building elevation is that its projection plane is vertical.However,most current drawing software are designed based on horizontal projection plane,which can＇t be used for drawing elevation directly.This paper,according to the principle of elevation measurement,describes a method solving the mentioned problem by using total station,CASS mapping software and coordinate conversion.Furthermore,results of accuracy analysis of coordinate conversion and elevation measurement are given.
