The Epigraph Reading Method using a Visualization Technique based on Morphological Characteristics of the Letters

Abstract

The epigraphy is a text or a picture engraved on metal or stone. One of advantages of rubbing of ancient inscription has been used in epigraphic field is simple. But the rubbing is not an optimal method in viewpoints of resolution and noise to decode the inscribed characters. In this study, we proposed a new research method that increases the possibility of a reading by reflecting the 3D characteristics of the engraved letters. The proposed techniques apply 3D scanning technology to obtain three-dimensional and high quality data of each of the letters in the epigraphy and use Ambient Occlusion visualization techniques to express the shade according to the 3D form of the letters. Research result enhances the readability of the letters that removed the damaged and worn information from the letters information of surface. This research contributes to narrow the scope of a particular letter and read to the controversial letters on the Pohang Jungsoengri Silla Stone Monument(Korea's national treasure number 318) ■ keyword :∣Epigraphy∣Rubbing∣3D Scanning∣Ambient Occlusion∣ 접수일자 : 2016년 10월 17일 수정일자 : 2016년 12월 29일 심사완료일 : 2017년 01월 02일 교신저자 : 최원호, e-mail : wonhosori@hanmail.net 각자된 글자의 형태적 시각화를 이용한 금석문 판독방법 741
