Estimation of Folding Operation Using Silhouette of Origami

Abstract

In this paper, we address a method for supporting origami folding process on origami. We focus on a folding operation with a view to under- standing the state of origami. We estimate the folding operations by using one camera. The folding opera- tion can be estimated by comparing origami shapes of before and after a folding operation. A silhouette model is introduced to grasp the correspondence of a state of an origami sheet to an applied folding op- eration. Comparing a silhouette with the shape of origami in a camera image, the folding operation can be estimated. Also, our method can distinguish the folding operation at high speed.
