摘　　要：随着社会的发展,人们对历史建筑物的保护意识逐渐加强。很多优秀历史建筑物在建造时并无设计图纸,因此一旦遭受破坏很难复原。为了保护历史建筑物,同时也为历史建筑物的管理、修缮、复建等提供参考资料,需采用测绘手段对历史建筑物进行全方面数字化存档工作。本文利用三维激光扫描技术对历史建筑物进行全方位测绘,得到历史建筑物的点云数据,再对点云数据进行拼接、过滤、横剖、建模等处理,得到建筑物的平面图、立面图、剖面图、三维模型等数字化成果。对数字化成果进行存档,为今后历史建筑物的保护、修缮等提供重要参考资料。With the development of society,people's awareness of the protection of historical buildings has gradually strengthened.Because many excellent historical buildings were constructed without design drawings,it is difficult to restore them once they are damaged.In order to protect historical buildings and provide reference materials for the management,repair,and reconstruction of historical buildings,it is necessary to use surveying and mapping methods to carry out all-round digital archiving of historical buildings.This paper uses 3D laser scanning technology to survey and map historical buildings in an all-round way,and obtain point cloud data of historical buildings.Then by processing the point cloud data,digital results such as the plan,elevation,cross-section,and 3D models of the buildings are obtained.It archives the digitized results to provide important reference materials for the protection and repair of historical buildings in the future.
