激光点云数据在异形建筑物竣工测量中的应用

Application of Laser Point Cloud Data in the Completion Surveying of Irregular Buildings

异形建筑物越来越多给竣工测量带来了极大挑战,利用三维激光扫描技术解决异形建筑物的竣工测量应用具有重要意义。选择连云港大剧院为研究对象,其由4个“球体”拼接而成,球体相互关联,又独立成块,建筑物外观形状上呈曲面特征。使用徕卡C10扫描仪获取激光点云数据,利用Cyclone软件进行数据预处理,采用Cyclone与CAD软件获取研究对象外轮廓有代表性的多截面信息,并与规划设计图对比分析。研究结果表明,使用三维激光扫描技术对异形建筑物进行竣工测量是可行的,具有良好的应用前景。

More and more special-shaped buildings have brought great challenges to the completion survey.It is of great significance to study the application technology of the completion survey of special-shaped buildings by using three-dimensional laser scanning technology.This paper chooses Lianyungang Grand Theater as the research object,it is composed of four“spheres”,the spheres are interrelated and independent into blocks,the appearance of the building is curved.Using Leica C10 scanner to acquire laser point cloud data,uses Cyclone software to preprocess data,and uses Cyclone and CAD software to acquire representative multi-section information of the object’s outline,and makes a comparison and analysis with the planning and design drawings.The results show that it is feasible to use three-dimensional laser scanning technology to complete the survey of special-shaped buildings,and it has good application prospects.
