三维激光扫描技术在剧场建筑测绘中的应用

Application of three-dimensional laser scanning technology in theater building surveying and mapping

鉴于传统建筑测绘采用全站仪、测距仪等单点测量方式,存在工作量大且效率低下等问题,将三维激光扫描技术应用到剧场建筑测绘工作中,以北京某剧场测绘项目为例,探讨三维激光扫描技术在数据采集、数据处理、建筑平立剖面图绘制和三维仿真建模等作业流程的实现过程。工程实例结果表明,利用三维激光扫描技术解决传统建筑测绘方法单点采集和效率低下的问题是行之有效的,可为剧场建筑测绘工作提供一种高效快速的解决方案。

In view of the large workload and low efficiency of traditional building surveying and mapping using single point surveying methods such as total station and rangefinder,three-dimensional(3D)laser scanning technology was applied to theater building surveying and mapping.Taking a theater surveying and mapping project in Beijing as an example,this paper discussed the implementation process of 3D laser scanning technology in data acquisition,data processing,building horizontal and vertical profile drawing and 3D simulation modeling.The results of engineering examples showed that it was effective to use 3D laser scanning technology to solve the problems of single point acquisition and low efficiency of traditional building surveying and mapping methods,which could provide an efficient and fast solution for the theater building surveying and mapping work.
