基于PhotoModeler Scanner的文物三维重建应用研究

本文研究了基于近景摄影测量原理实现文物三维重建的可行性。通过实验,总结了基于近景摄影测量软件Photo Modeler Scanner软件对文物进行采集和重建的可行性方法和基本流程。即在作业现场利用普通数码相机获取文物数字影像,利用Photo Modeler Scanner对影像进行处理,通过相对定向、密集匹配、构TIN和纹理映射等处理,建立文物的DSM,重建带有真实纹理并可量测的文物三维模型。

This paper studies the feasibility of close range photogrammetry principle to realize 3D reconstruction based on cultural relics. Through the experiment, the paper summarizes the feasibility method and basic process that uses close range photogrammetry software Photo Modeler Scanner software for acquisitng and reconstructing the relics digital image. The relics digital images are achieved by using common dig ital camera at the operation site and handled by Photo Modeler Scanner software. The process contains relative orientation, dense matching structure, TIN processing, texture mapping, establishing artifacts' DSM and rebuilding three-dimensional model measurement artifacts with real texture.
