摘　　要：地仗是中国古建油饰工艺的精华所在,传统方法很难对该工艺流程进行真实量化记录。利用三维扫描技术进行空间数据几何处理、纹理映射和三维重构,可以得到准确率极高的文物三维数据。这些数据不仅为传统工艺传承保护提供客观依据,同时为修缮工艺的虚拟和实体复原提供数据支持。相比于传统文字、二维影像等记录手段,三维技术可以在古建筑修缮工艺实施过程中,更准确地获得古建筑的高精度几何信息、拓扑信息和纹理信息,能够更全面、永久地保存和传播古建筑文化遗产,使传统工艺真正实现可感、可控的永久性保存。The traditional ground layer technique is the real essence of the oil and painting technique in Chinese ancient architecture. Because of the arbitrariness, it’s hard to record the accurate data of repair procedure. The most contribution of this paper is the digitalization work for the repair process recording this traditional Chinese construction technique. The painting technological process and digitalization work including data collection, geometry processing and interactional display of 3D models are detailed discussed in this paper. Comparing with traditional methods, our 3D techniques can obtain the accurate surface data of ancient architecture, and provides new ways to preserve and spread the cultural heritage in a more comprehensive and permanent way.
