摘要
在对历史建筑进行测绘的过程中,利用传统的测绘手段难以获取其复杂结构的三维空间信息、特征结构信息,而采用三维激光扫描仪能无接触且快速地完成历史建筑物的空间数据采集,基于点云数据能高效、准确地进行历史建筑物的数字化成果制作。论文从点云数据获取、配准拼接、去噪、优化等方面阐述了三维激光扫描的关键技术,以景德镇某小镇的历史建筑物为研究对象,利用三维激光扫描仪进行点云数据采集,基于点云进行二、三维数字化成果生产。结果表明,点云质量及最终成果精度均能满足相关规范要求,充分证明这项技术高效、可靠。
In practical surveying and mapping of historical buildings,it is difficult to obtain the 3D spatial information and characteristic structure information of complex structures by traditional surveying and mapping methods.3D laser scanner can quickly complete the spatial data acquisition without contact,and the digital results of historical buildings can be made efficiently and accurately based on the point cloud data.This paper expounds the key technologies of 3D laser scanning from the aspects of point cloud data acquisition,registration splicing,noise reduction and optimization,and takes the historical buildings of a small town in Jingdezhen City as the research object,uses 3D laser scanner for point cloud data acquisition,and based on which carries out 2D and 3D digital production.Both the quality of the point cloud and the accuracy of the final result can meet the requirements of relevant specifications,which fully proves the efficiency and reliability of this technology.
