Research into Restoration of Destructed Ancient Tombs (Kofun) Used by Aerophotographs

本研究以全国范围内现存的古墓为研究对象，通过航空摄影采集古墓照片，尝试对50座被破坏的古墓进行视觉复原。本研究中的古墓被归类为日本古代时期建造的“前房-公园坟”，在本次调查中，我们将被破坏的古墓分为以下几类：第一，336座古墓被破坏和半破坏。第二：204座坟墓被部分破坏。同时，我们收集了与此相关的资料和照片，并将其保存在数据库管理中，在过去的四年里，照片的数量达到了1500件，相当于700座古墓。这些照片通过航空摄影立体镜进行了测量，并被挑选成合适的照片进行存档和数字化。此外，我们还观察了这些墓葬的类型情况，并试图对其进行分析和图形化 ...更多信息 并利用CBS公司的Map Matrix和Feature Matrix对它们进行了分类。虽然上述软件于2009年引入本研究，并于2010年开始全面运行，迄今为止，已经可以对约50座墓葬和多组墓葬进行自动数据处理，并恢复其规模和平面类型，但仍存在一些问题：例如，对于古墓的类型，尽管有一定程度的视觉观察，但在自动数据处理中，诸如墓的边缘和层的情况等挖掘细节不能完全实现。此外，在人工修复研究资料中的某些部分时，我们发现它不允许大规模生产，需要足够的技能。尽管存在这些问题，但可以得出结论，我们已经实现了最初的期望：通过对收集到的材料进行彻底调查，我们实现了重新评估酋长墓建造时间的前景。在重新评价主要墓葬的过程中，我们以2009学年为止的调查为基础，对宫坂地区进行了研究，并以航空照片的分析和自动数据处理的结果为基础，通过重新审查全国古墓的状况，再次考虑了“善房-高原”在古代日本历史上的作用。少

In this study, we researched ancient tombs existed nationwide and collectedthe photographs of them by aerial photography, and attempted to visually restore fifty destructed ancienttombs. The ancient tombs in this study are categorized as"Zenpou-Kouenfun", constructed during the ancient times in Japan.In this survey of the destructed ancient tombs, we classified them into several groups; firstly : 336 tombs as having been destructed and half-destructed. Secondly: 204 tombs as having been partially destructed. At the same time, we collected materials and photographs related to the subject, and preserved them in database management.During the last four years, the amount of the photographs reached 1500 pieces equivalent for 700 ancient tombs. The photographs were surveyed through a stereoscope for aerial photography and selected into suitable ones to be archived and digitized. Furthermore, we observed the conditions of types of those tombs, and attempted to analyze and graphically visualiz … More e them, using Map Matrix and Feature Matrix of the CBS Company. Although the software above mentioned was introduced in 2009 into this study and started a full-scale operation in 2010, so far it has been possible for approximately 50 tombs and several groups of the tombs to be automatically data processed, and restoration of their scale and plane type was also achieved.However, several problems are left : for example, considering the type of an ancient tomb, such miner details as the edge of a tomb and the conditions of the layer cannot be realized completely in automatic data procession, in spite of visual observation to a certain degree. In addition to that, in attempting to restore certain parts in research materials manually, we found that it did not admit of mass production in need of sufficient skills.Despite these problems, it is concluded that our original expectations have been fulfilled : we achieved a prospect for reevaluation of the time when the tombs for the chiefs were built, through investigating thoroughly the materials collected. Of the reevaluation of the chief tombs, we studied in the Mimasaka area on the basis of the survey having been done until the 2009 academic year, and considered once again the role of"Zenpou-Kouenfun" in the history of the ancient Japan by reexamining of the conditions of ancient tombs nationwide, on the ground of the analysis of the aerial photographs and the results of automatic data processing.
