A reconstructive study of Kofun period armour production using three-dimensional laser measurement

人们对古坟时期盔甲的工匠群体和制造过程知之甚少。 在这项研究中，我们进行了几个坦克胸甲的检查，以更好地了解他们是如何产生的。由于仅凭二维信息很难比较这些作品的复杂结构，因此使用激光来创建三维测量。根据收集的数据，我们能够确定三组每组由两个胸甲组成，其中作品的铁板的大小，形状和方向是相同的或密切相关的。这些发现表明，每个组中的胸甲可能是通过使用相同的模板式蓝图或片上制作的。

Little is known about the artisan groups and manufacturing processes involved in the creation of Kofun period armour. In this study, we conducted an examination of several tanko cuirasses in order to better understand how they were produced. Since two-dimensional information alone makes a comparison of these works' complex structure difficult, a laser was used to create three-dimensional measurements. Based on the collected data, we were able to identify three groups each comprised of two cuirasses, in which the size, shape, and orientation of the iron plates of the works were either identical or closely related. These findings suggest that cuirasses in each of the groups likely were manufactured through the use of the same template-like blueprint, or katagami.
