历史文化资源建档中的测绘新技术应用

The application of new technologies in surveying and mapping on archiving historical and cultural resources

以历史文化街区、历史文化名镇名村、历史建筑等为代表的历史文化资源,是城市历史文化传承的重要载体。为更好地保护历史文化遗产,近年来各地广泛开展了历史文化资源保护的相关工作。在重庆市开展的历史文化资源测绘建档工作中,项目组综合运用了三维激光扫描、倾斜摄影等空地一体的非接触式数据采集,以及点云融合、分类、去噪、建模、自动绘图等技术,形成了以二维图形、激光点云、实景三维、精细三维、空地影像和高清照片相结合的测绘成果体系,顺利完成了各类历史文化资源的建档和入库,取得良好效果。

The historical and cultural resources represented by historical and cultural blocks,famous towns and villages,and historical buildings are important carriers of urban historical and cultural inheritance.To better protect historical and cultural heritage,in recent years,related work on the protection of historical and cultural resources has been widely carried out all over the country.In the process of mapping and archiving historical and cultural resources in Chongqing,the project team comprehensively utilized non-contact data collection methods such as three-dimensional(3D)laser scanning and oblique photography,as well as technologies such as point cloud fusion,classification,denoising,modeling,and automatic mapping.A surveying and mapping result system has been formed that combines two-dimensional(2D)graphics,laser point clouds,3D real scene,fine 3D,air-to-ground images,and high-definition photos,completing the archiving and storage of various historical and cultural resources,which achieved good results.
