【摘要】 介绍了虚拟展览馆的基本概念,所需的软件及其功能,以及构建虚拟展览馆的各个步骤。针对三峡文化遗产的数字化工作,着重讨论了基于单张展品图像进行建模的技术。包括基于单张图片的相机校准技术的两种原理以及利用这些原理进行相机校准的各种方法,并给出了校准技术的一个实现算法。接着介绍了在相机校正的基础上进行建模的技术以及这个技术的应用。更多还原

【Abstract】 This paper introduces the concept of virtual exposition, specifies its software composition and the steps to construct a virtual exposition. Hoping to facilitate the digitization of cultural heritage of the ThreeGorges, we emphasize on the single-image-based modeling technique, with a little prior geometry metric information. To do that, we first summarize the principles of camera calibration from single image and classify several of such calibration techniques, then give an implementation algorithm. Finally, we introduce the modeling techniques based on the calibration result and give some examples and applications.更多还原
