ITR: Solving the Puzzle of the Forma Urbis Romae

该项目将使用计算机形状匹配算法来组装古罗马巨型大理石地图Forma Urbis Romae的剩余碎片。原件宽60英尺，高45英尺，可以追溯到公元2世纪。地图现在由1163个碎片组成，并且是不完整的。对于计算机图形学研究来说，将剩余的碎片拼接在一起是一个独特的挑战。如果成功，它将为考古学家提供一个非常重要的资源。为了测试图形算法，需要花费巨大的成本和精力来获取原始数据。斯坦福大学的一组教职员工和学生花了一个月的时间在现场使用激光扫描和数码彩色摄影技术对每一块已知碎片的形状和表面外观进行数字化。经过处理的原始数据现在由80亿个多边形和6000幅彩色图像组成，总计40 GB的数据。该项目希望制作和传播这一著名考古文献的3D模型和照片的数据库，并在此过程中，为同类物体的形状匹配贡献新的算法。

This project will use computer shape matching algorithms to assemble the remaining fragments of the Forma Urbis Romae, a giant marble map of ancient Rome. The original, measuring 60 feet wide by 45 feet high, dates to the second century AD. The map now consists of 1,163 fragments, and is incomplete. Piecing the remaining fragments together is a unique challenge for computer graphics research. If successful, it will offer to archeologists a resource of great importance. In order to test the graphics algorithms the raw data was acquired at great cost and effort. A team of faculty and students from Stanford spent a month on site digitizing the shape and surface appearance of every known fragment using laser scanning and digital color photography. The processed raw data now consists of 8 billion polygons and 6 thousand color images, amounting to 40GB of data. The project hopes to produce and disseminate a database of 3D models and photographs of this famous archaeological document and in the process, contribute new algorithms for shape matching for objects of kind.--
