Computer Analysis on Patterns of the Keyhole Tomb Mounds

1997-1998年的研究成果总结如下：(1)对本项目开始前获得的所有锁眼墓数据进行了整理，以便于对墓丘进行模式分析。最近对2000多座坟墓进行了调查，将他们的数据添加到现有的收集中。重点是收集墓丘的等高线图进行模式分析。部分数据采集已转化为电子版，数据库已实验性地在以下网站上发布：http: //www.ozlab.osakac.ac.jp/KOFUN/(2)Measurement对500多个墓葬的长度、直径等七个维度进行了分析，搭建了统计模式分析的平台。然后，在一个特殊的局部区域，检测出了锁眼墓丘时间变化的几个定量规律。在此基础上，设计了基于知识的古墓修复系统生成的概念方案。(3)对钥匙孔墓多媒体数据库进行了基础调查，旨在将图形、图像和地理数据灵活联系起来，进行广泛的模式分析。(4)在古代风景可视化中进行了自动纹理合成实验。这种技术将有助于计算机图形化图像的生成，这些图像将由上述修复的古墓丘组成的古代风景形象化。

Summary of research results during 1997-1998 includes :(1)All data of the Keyhole tombs acquired untill this research project started have been reorganized so as to be appropriate to pattern analysis on the tomb mounds. More than 2000 tombs have newly been investigated, adding their data into the existing collection. Emphasis has been placed on collecting contour maps of the tomb mounds for pattern analysis. A part of the data collection has been transformed into the electronic version, The database has experimentally been released at the following Web site :http : //www.ozlab.osakac.ac.jp/KOFUN/(2)Measurement of seven dimensions such as length, diameter and so on of the tomb mound has been carried out for each of more than 500 tomb mounds to build a platform of statistical pattern analysis. Then, several quantitative rules of temporal change of the Keyhole tomb mounds have been detected in a special local region. From this, a conceptual scheme of a knowledge-based system to generate the restored tomb mound has been designed.(3)A basic investigation on a multimedia database of the Keyhole tombs has been carried out, aiming at flexible link between pictorial, image and geographical data for extensive pattern analysis.(4)Automatic texture synthesis has experimantally been taken place for visualization of ancient scenery. This technique will be useful for computer graphical generation of images which visualize the ancient scenery consisting of such restored tomb mounds as mentioned above.
