面向原真性保护的历史建筑三维数据测绘适应性方法研究

Research on Adaptive Method of Historical Building 3D Data Mapping for Authenticity Protection

由于实景测绘技术本身的全景测绘特点,导致在进行三维数据采集时容易造成极大的数据冗余;另一方面,由于缺乏分层次的采集方案,统一分辨率的数据采集又造成了若干重点部位的数据精度不足,这些都给历史建筑数字化的应用带来较大不确定性,从而限制了历史建筑数字化保护的深入发展。针对这一问题,以面向原真性保护的需求为主,详细探讨了历史建筑分层次、多细节的三维数据测绘适应性方法,同时以实际工程为例进行应用尝试,应用结果表明研究内容具备充分的必要性与可拓展性,是未来历史建筑精细数字化测绘的可行方案之一。

Due to the characteristics of panoramic mapping of the real scene mapping technology,it is easy to cause great data redundancy when collecting 3D data;on the other hand,due to the lack of hierarchical acquisition scheme,data acquisition with unified resolution has resulted in insufficient data accuracy in several key parts,which has brought greater uncertainty to the application of digital historical buildings,thus limiting the further development of digital protection of historical buildings.Aiming at this problem,based on the demand of authenticity protection,this paper discusses in detail the hierarchical and multi detailed 3D data mapping adaptive method of historical buildings.At the same time,it takes the actual project as an example to make an application attempt.The application results show that the research content has sufficient necessity and expandability,and is one of the feasible plans for the future fine digital mapping of historical buildings.
