摘要
古建筑精细测绘是建筑遗产保护的基础性工作。单一的全站仪测量、摄影测量与三维激光扫描方法在精度、效率和数据处理方面存在不足。为此,提出了一种多传感器集成和融合处理的古建筑物精细测绘的方法。首先,对古建筑物精细测绘的需求和难点进行了分析,剖析了单一测量方式古建筑测绘存在的问题;其次,提出了集成全站仪、激光测距、高分辨率近景摄影测量、地面三维激光扫描和全景测量的古建筑精细测绘的技术流程,对其关键处理方法进行了探讨分析;最后,以武当山两仪殿为例,开展了多测量手段集成古建精细测绘工程实践,测量精度满足古建筑精细测绘要求,可快速制作古建筑物图件和构件精细模型,为两仪殿保护提供精细测绘成果。
Detailed and precise surveying of ancient architecture is the basis for the conservation of the architectur- al heritages. A single surveying method, such as total station measurement, photogrammetry and laser scanning method, can be defective in accuracy, efficiency or data processing. A multiple sensor integration method for ancient architecture, which provides improved detail and precision, is proposed. Firstly, the requirements and dif- ficulties for ancient architecture surveying are analyzed. The problem of single surveying approach for ancient archi- tecture is discussed. Secondly, a technique flowchart of multiple sensor integration surveying approach with better detail and precision is designed, which integrates total station, laser ranging, close -range photogrammetry, terres- trial laser scanning and panoramic three -dimension measurement. The key data processing methods are discussed. Finally, a detailed surveying of an ancient architecture Liangyi Dian at Wudang Mountain, is designed and imple- mented with the proposed approach. The result showed that the accuracy can meet detail and precision requirements of ancient architecture surveying. The method can quickly create maps and accurate models of components of ancient architecture, which provide accurate surveying results for the protection of Liangyi Dian.
