基于激光扫描技术的不规则构筑物建模应用OA
Application of modeling irregular structures based on laser scanning technology
三维激光扫描技术能够快速获取海量高精度三维点云,在复杂不规则构筑物模型重建应用方面具有优势.文章以广东某校标志雕塑为研究对象,从前期准备、外业数据采集、点云数据处理和三维模型重建方面进行研究.结果表明,采用三维激光扫描技术对不规则构筑物进行扫描,能够快速获取完整的构筑物表面点云,重建的模型能够很好地展示真实结构的特征,为城市的不规则构筑物模型重建提供参考.
3D laser scanning technology can quickly obtain massive high-precision 3D point clouds,which has advantages in the reconstruction and application of complex irregular structure models.This paper takes the logo sculpture of a school in Guangdong Province as the research object,and studies the preliminary preparation,field data acquisition,point cloud data processing and 3D model reconstruction.The results show that the scanning of irregular structures by 3D laser scanning technology can quickly obtain a complete surface point cloud of structures,and the reconstructed model can well display the characteristics of the real structure,which provides a reference for the reconstruction of irregular structure models in the city.
