transform method, after establishing 3D digital data by interpreting 28 models about the pattern of the bell body and the 
surface of the bell of Dangjwa, Beechonsang, Yuguwk, Yongnew, Sangdae and Hadae. For the analysis of diverse 
forms about the bell, this research was established base cap by creating 3-dimensional model(TIN) and performed the 
geometrical form analysis of section, surface volume, deflection and circular form etc. and the visual analysis of 3 
dimensional perspective drawing, plane projection drawing, contour map and modeling etc. Thus, this findings will be 
applicable for the basic data for acoustic analysis study, casting technique study, and fine art history study etc, and the 
analysis technique to use image media will be able to be utilized widely for archaeological study and fine art history 
study etc. including the safety diagnosis for cultural properties protection.

1.2 IMAGE ACQUISITION 
This research was used the analysis technique to use image medium for the precise 3 dimensional location 
measurement about various patterns casted on the bell and the surface and for the analysis of digital data. For acquiring 
more precise vector data, this researcher acquired total 28 models such as 4 models of bellbody, 2 models of dangjwa, 
beechonsang, each 4 models of yuguwk, 4 models of upper region plane, 2 models of sangdae and 8 models of yongnew.
