点云-数字化测绘方法在宫庙建筑测绘中应用

The application of Point-cloud surveying and mapping method in temples building

点云-数字化测绘方法通过运用三维激光扫描仪技术采集古建筑点云数据,并通过数字建模将成果展现。该技术能快速获得测绘对象的三维数据,但是在点云数据处理、点云-数字化成果过程转化等方面还存在许多不足。文章选取福州地区代表性的传统宫庙建筑作为研究对象,对古建筑测绘全过程中踏勘、三维扫描、测量、数据处理、建模等各个环节展开研究。针对测绘过程出现的点云数据降噪、点云模型清理、庞大数据文件的采集记录保存提取、不同数据处理平台的数据传递、点云文件数字化建模精确性等问题,寻找解决方案。研究发现,点云-数字化测绘方法能够快速地获取数字化信息,但是在实际古建筑测绘过程中还不能完全替代传统古建测绘方法,只能作为其创新性的发展与补充。

Point-cloud surveying and mapping is a method which adopts the 3 D laser scanning to collect point-cloud data of the traditional architecture and present the result through digital modeling. This method can quickly collect 3 D data from surveying buildings,while its deficiencies are found in aspects of point-cloud data processing and the transformation of point-cloud digitalized results. With some representative traditional temples in Fuzhou as research objects,this paper carries on the research in following procedures： reconnaissance,3 D scanning,surveying and mapping,data processing and computer modeling,etc. With denoising,cleaning,retention and extraction of point-cloud records,the research aims at the solution to problems of data transmission,digitized modeling of point-cloud documents. It＇s found that point-cloud mapping acquires the digitized information rapidly. In the process of ancient architecture mapping,however,it cannot replace the traditional mapping and is no more than a supplement to it.
