Dynamic Depth-of-Field Projection for 3D Projection Mapping

Abstract

Demonstration for a dynamic depth-of-field projection mapping on a 3D moving object would be performed. Conventional projection mapping was limited on 2D space, due to their narrow depth-of-field projection range. Our system included a high-speed projector, a high-speed variable focus lens, a depth sensor by a stereo camera, so that the depth information would be detected and then served as feedback to correct the focal length of the projection. As a result, a projection mapping would be well-focused projected on a 3D dynamic moving object.
