Proposal : IIS-0087158Institution: Stanford UniversityPI: Marc LevoyTitle: Creating Digital Archives of 3D ArtworkRecent improvements in laser rangefinder technology, together with algorithms for combining multiple range and color images, allows accurate digitization of the external shape and surface characteristics of many physical objects. This capability makes it possible for the first time to digitize and archive substantial bodies of three-dimensional artistic and cultural artifacts, such as statues, buildings, and archeological remains. Although the methodologies needed to create and manage digital archives of two-dimensional artifacts have matured substantially in the last ten years, the jump from two to three dimensions poses new problems. These are problems of both scale and substance, and they touch on every aspect of digital archiving: storage, indexing, searching, distribution, viewing, and piracy protection. This pilot project, will focus on the following subproblems of this new domain:(1) cataloguing 3D artworks using techniques from image-based rendering,(2) searching catalogues (and the Internet) for 3D models or rendered views(3) protecting 3D archives against piracy using robust 3D digital watermarking,(4) efficient streaming of 3D models over networks of limited bandwidth, and (5) real-time display of large 3D models on low-cost PCs.As test data, a 250 gigabyte archive of the sculptures of Michelangelo and the fragments of the Forma Urbis Romae, a giant marble map of ancient Rome will be used. The data for this archive was generated during a year-long digitization effort called the Digital Michelangelo Project.

提案：IIS-0087158机构：斯坦福大学PI：Marc Levoy题目：创建3D艺术品的数字档案激光测距仪技术的最新改进，以及用于组合多个范围和彩色图像的算法，允许许多物理对象的外部形状和表面特征的精确数字化。 这一能力首次使三维艺术和文化文物（如雕像、建筑物和考古遗迹）的实体化和存档成为可能。 虽然在过去的十年中，创建和管理二维文物数字档案所需的方法已经基本成熟，但从二维到三维的跳跃带来了新的问题。这些都是规模和实质性的问题，它们涉及到数字存档的各个方面：存储、索引、搜索、分发、查看和盗版保护。 这个试点项目将集中在这个新领域的以下子问题：（1）使用基于图像的渲染技术对3D艺术品进行编目，（2）搜索目录（和互联网）以获得3D模型或渲染视图，（3）使用强大的3D数字水印保护3D档案免受盗版，（4）在有限带宽的网络上有效地传输3D模型，以及（5）在低成本PC上实时显示大型3D模型。作为测试数据，将使用250 GB的米开朗基罗雕塑和罗马城市广场碎片档案，一个巨大的古罗马大理石地图。 这个档案的数据是在一个为期一年的数字化工作中产生的，称为数字米开朗基罗项目。
