A mask making for the projection mapping to the distorted cylindrical surface

Abstract

Projection mapping which projects to the three-dimensional architecture has attracted much attention as a new representation of the video content. In this study, two methods for automatically generating a mask image from the projection image are proposed and implemented. The former is by obtaining the object's image from the substantially same position as the projector, and by extracting silhouette. The latter is by extracting a shadow of the tube which is projected on the wall. Using the objects created by bending the aluminum flex tube and a production process of the projection mapping, two media art exhibition were carried out.
