Method of Hiding Projection Pattern for Depth Estimation in Interactive Art

Abstract

In recent years, projection mapping has become popular in the commercial and artistic fields. Among them, there is projection mapping that the viewer's motion and the movie interact. They are called interactive art, and are attracting attention. On augmented reality, pattern hiding methods have studied to estimate depth using only a camera and projector. However, there are color breaking at the border of the grid and flicker occurs when pattern change. Therefore, in this study, we used the phase shift method for interactive art, and investigated the possibility of depth estimation. As a result, we calculated phase image and reduced color breaking and flicker. The errors in the phase images, it was found that the accuracy was sufficient to recognize an adult.
