Projector camera system for realtime 3D scanning

An active 3D scanning device which can capture a sequential motion in realtime is strongly demanded for 3D display and other VR systems. Since most previous and commercial products basically recover the shape with a point or a line for each scan, fast motion can not be captured in principle. One solution for the purpose is to use a single pattern (one shot scan). However, they often have stability problems and their result tend to have low resolution. In our recent study, we have developed a system which achieved dense and accurate 3D reconstruction from only a single image. The proposed system also had the advantage of being robust in terms of image processing. In this presentation, we introduce outline of our system, several applications and results.
