Research on Technical Route of Historical Building Census in Tianhe District of Guangzhou

历史建筑普查涉及专业跨度大,普查范围广,测量难度大,历史建筑物数量多,分布分散等诸多棘手问题。本文通过多时相、多源地图数据叠置分析,先内后外的变化检测技术代替人工盲目筛选,并基于地面Li DAR技术对重要线索进行扫描、建模归档,为历史建筑的保护和修复提供了精确的资料数据,对同类普查项目具有一定的示范意义。

Census of historic buildings involve many problems,such as wide profession span,wide range,difficult measurement,large number ol historical buildings,scattered distribution and so on.This paper replace the manual blind screening with change detection techniques,which based on the overlay analysis of multidate and multisource map datum.LiDAR technology provides important clues via scanning,modeling and archiving.It provides accurate data and data for the protection and restoration of historical buildings,and has certain demonstrative significance for similar census projects.
