激光三维扫描技术用于古建筑测绘的研究

Research on mapping of ancient architecture based on laser 3-dimension scanning technology

传统的古建筑测绘以直尺和角尺、垂球等工具直接量取建筑物及其构件的尺寸,而获取的最终资料是"图样"(即图纸)和一些文字记录。而重要古建筑在大规模修复前则要求进行精确的测绘工作,为古建筑保护提供第一手资料,同时也为研究中国古建筑史和建筑理论提供重要资料。激光三维扫描技术能够快速、精确、多方位地获取静态物体的三维模型,并对模型进行进一步的分析和数据处理。该方法在故宫的修复测绘中进行了大量的实验,取得了较好的效果,为古建筑测绘的数字化提供良好的平台。

In traditional ancient architecture mapping,the dimension of the architecture and its components is directly measured through the tools such as ruler or ruler with plummet,while the final acquired material is “pattern”(also called drawing) and some character record.But precise mapping work is required before the important ancient architecture is to be largely repaired,in order to provide first-hand material for ancient architecture protection and to provide important data for research on history of Chinese ancient architecture and theory of architecture.Through Laser 3-Dimension Scanning technology the 3-D model of static object can be acquired fast,precisely and multi-directionally,the model and its data can be analyzed and proceed further.This method has been tested repetitiously in the mapping work for repair of the Forbidden City,got good effect,and provided good platform for digitalization of the mapping of ancient architecture.
