摘　　要：异形建筑承载着人类巨大的想象空间,也常常成为一个城市的标志性“名片”,在其施工建设过程中常需要进行立面测量,但是由于异形建筑其外立面极不规则,采用常规的测量方法进行测量,效率极低且精度不高,三维激光扫描技术在异形建筑物的立面测量中有着传统测量方式无法比拟的技术优势,其能快速准确地获取建筑物表面点云数据。本文以某工程实践为例,将三维激光扫描应用到异形桥梁结构立面测量中,制定了一套切实可行的立面测量技术流程,研究结果对异形建筑物立面数据的有效采集、后期管理以及建立完善的建筑物档案资料具有较强的参考价值。Special shaped buildings carry a huge space for human imagination,often serve as a landmark “business card” of a city,and their facades often need to be measured in the process of construction.However,due to the extremely irregular exterior of the special shaped buildings,using conventional measurement methods for measurement is extremely inefficient and inaccurate.3D laser scanning technology has technical advantages that cannot be transcended by traditional measurement methods in the fa9ade measurement of special shaped buildings,and it can quickly and accurately obtain the point cloud data of the building surfaces.This paper takes an engineering practice as an example,applies 3D laser scanning to the facade measurement of special shaped bridge structures,and develops a set of feasible facade measurement technology process.The research results have strong reference value for the effective collection of special shaped building facade data,later management and the establishment of complete building archives.
