大型古建筑文物结构复杂，数字化保护工作繁琐且沉重，而三维激光扫描技术作为测绘领域的一项高新技术，具有无接触测量、效率高等优点，将三维激光扫描技术应用到文物保护领域将成为精细、快捷的文物档案保护手段之一。以某大型仿古建筑为例，详细阐述了数据采集的技术和方法，结合在数据处理过程遇到的一些问题进行了探讨和总结。最终给出该建筑物的局部纹理映射图和各类效果图，为三维激光扫描技术在大型古建筑三维重建中的应用提供借鉴和参考。%Large historic building relic commonly has complex construction, and the digitization protection is a cockamamie and heavy workload. However, as a new technology in a surveying and mapping field,3D laser scanning has the advantages of non-contact surveying and high efficiency. Applying 3D laser scanning to his-toric preservation field will become a precise and convenient method. As an antique architectural for example, has a detailed presentation on method and technology in field work,to discuss and summarize some questions when data processing. Finally, this article give the building's local texture maps and other maps, which will provide reference for the application of 3 D laser scanning technology in the 3 D modeling reconstruction of the ancient buildings.
