三维激光扫描技术在落架古厝全面测绘中的应用

Application of 3D laser scanning technology in comprehensive surveying and mapping of Luojia ancient houses

新时代对古厝的保护和利用越来越重视,传统村落中的古厝濒临破坏或者灭失。落架迁建是对具有保留价值的古厝进行保护的方式之一。为了能更好地保存古厝的原始风貌,利用三维激光扫描技术对落架古厝进行全面测绘。通过激光扫描仪快速获取物体表面的三维坐标数据,生产高密度的点云数据集,可以精确反映物体的三维结构和表面特征,更好地记录古厝的空间信息及R.G.B颜色信息,为古厝的迁建提供精准的设计资料。文章主要论述三维激光扫描技术在古厝建档测绘中的应用,为其他历史文化资源的保护提供借鉴。

In the new era,the protection and utilization of ancient houses have become to more important,and the ancient houses in traditional villages are facing destruction or loss.The relocation and reconstruction of dismantled houses is one of the protection methods for ancient houses with preservation value.In order to better preserve the original style of ancient houses,3D laser scanning technology is used to conduct comprehensive surveying and mapping of dismantled ancient houses.By quickly obtaining the 3D coordinate data of the object surface through a laser scanner and producing a high-density point cloud dataset,it can accurately reflect the 3D structure and surface characteristics of the object,it better to record the spatial information and RGB color information of the ancient houses,and provide accurate design materials for the relocation and reconstruction of the ancient houses.This article mainly discusses the application of 3D laser scanning technology in surveying and mapping for the archiving of ancient houses,providing a reference for the protection of other historical and cultural resources.
