This study aims to investigate and determine the actual size of the “cheok” scale—the traditional weights and measures of Korea—to aid in data construction on the recognition of ancient drawings in the field of artificial intelligence. The cheok scale can be divided into Yeongjocheok, Jucheok, Pobaekcheok, and Joryegicheok. This study calculated the actual dimensions used in the drawings of Tonga and Eonjo contained in Jaseungcha Dohae by Gyunam Ha BaeckWon, which helped us analyze the scale used in the southern region of Korea in the 1800s. The scales of 1/15 cheok and 1/10 cheok were used in the Tonga and Eonjo sections in Jaseungcha Dohae, and the actual dimensions in the drawing were converted to the scale used at the time. Owing to the conversion, the dimensions in the drawings of Tonga were converted to 30.658 cm per cheok, and ~31.84 cm per cheok for Eonjo. In this manner, the actual dimensions used in the southern region of Korea around the year 1800 were restored. Through this study, the reference values for drawing recognition of machinery drawings in Korea around 1800 were derived.

古图识别尺寸恢复

本研究旨在调查和确定“cheok”标尺（韩国的传统度量衡）的实际大小，以帮助构建人工智能领域古代绘画识别的数据。尺量表可分为永珠尺、主尺、破白尺和丈律尺。这项研究计算了 Gyunam Ha BaeckWon 在 Jaseungcha Dohae 中包含的汤加和 Eonjo 图纸中使用的实际尺寸，这有助于我们分析 1800 年代韩国南部地区使用的比例。Jaseungcha Dohae的Tonga和Eonjo部分使用了1/15 cheok和1/10 cheok的比例尺，图纸中的实际尺寸已转换为当时使用的比例尺。由于转换，汤加图纸中的尺寸被转换为每尺 30.658 厘米，约 31 厘米。Eonjo 的每 cheok 84 厘米。通过这种方式，1800 年前后在韩国南部地区使用的实际尺寸得以恢复。通过这项研究，推导出了1800年前后韩国机械图纸的图纸识别参考值。
