Projection mapping on a moving surface

This research aims at overcoming this limitation and realizes dynamic projection mapping in which dynamically-changing real-world and virtual visual information are completely merged in the level of human visual perception. This high-speed dynamic projection mapping requires a high-speed projector enabling high-frame-rate and low-latency projection. In order to meet this demand, we have developed a high-speed projector “DynaFlash” that can project 8-bit images up to 1,000fps with 3ms delay.In particular, as a challenging target for the dynamic projection mapping, we focus on a non-rigid surface. Sensing of non-rigid surface deformation is difficult to be achieved at high speed because it has high degrees-of-freedom and involves self-occlusions as well as external occlusions. Our newly proposed method overcomes this limitation. Our method can obtain the deformation robustly at 1,000 fps by using an originally proposed marker “Deformable Dot Cluster Marker”, even when the target causes large deformation and occlusions.
