摘要: 以唐小雁塔遗址的数字化展示为应用背景,针对文化遗址的真实感建模和三维虚拟展示问题,提出一种基于大场景三维激光扫描技术的遗址数字化方案,设计一种基于激光同步扫描图像、采用局部纹理映射的遗址三维真实感建模方法,利用GIS和虚拟现实技术开发一个文化遗址三维虚拟展示系统。实际应用结果证明,该系统可有效提高文化遗址的三维虚拟展示效果。

Abstract: Taking the Small Wild Goose Pagoda in Tang Dynasty as the case, aiming at the problem of 3D reality-based modeling and virtual exhibition for culture archaeological sites, this paper proposes a scheme of 3D digital data acquisition of the large archaeological sites by combining the technologies of 3D laser scanning of the large scene and the digital photography. Based on the laser-synchronized visual image of the ancient buildings, it offers a method of 3D reality-based modeling from real data with the adoption of the local texture mapping, and introduces the systematic architecture, technology roadmap and all key technologies of 3D desktop virtual walkthrough system based on GIS and virtual reality technology for the large archaeological sites. Application proves that the system can improve 3D virtual exhibition effect of cultural archaeological sites.

Key words: culture archaeological site, 3D measurement, 3D reality-based modeling, virtual exhibition
