Geometric Correction Using Multiple Projectors for Stage Direction System

Abstract

Recently, there are many space directions by using projection mapping to interior space. Especially for stage directions, it can improve stage effects and need only simple arrangements for stage settings. However, in order to show highly immersive theatrical performance, image projection with high accuracy for wide area like a theater is strongly required according to both the scenario and a shape of the space. Therefore, in this research, we propose an effective geometric correction combining both a fish-eye lens camera and a normal lens camera. Only with a simple procedure and the commodity cameras, we can provide seamless multi-projection for the whole of the theater.
