Preliminary study on automatic printing system for film package considering distortion

This study targets the process that forms three-dimensional plastic film from a two-dimensional printed arbitrary pattern. When three dimensional film is formed from two dimensional, expansions and contractions occurs. In this paper, we introduce an automatic printing system that form two-dimensional film includes partial expands and contractions to observe it naturally in three-dimensions. Our key idea is to extract three-dimensional distances with photometric stereo and to map two-dimensional patterns with Multi Dimensional Scaling (MDS) methodology. The purpose of this study is to develop an automatic printing system to form three-dimension. At present, our study provided useful information with photometric stereo and MDS, however, Further study is under way to develop the printing system.
