Assistance system for designing mirrored surface using projector

We propose a system with camera and projector to show specular reflection of surrounding environment on the real object. At first, active shape measurement with pattern light projection is performed to obtain precise shape of the object rapidly. Then, rendered specular pattern using the shape information is projected on the real object. Our system also recognizes the status of work operated by the designer, and shape measurement and visualization are done only when the worker wants to evaluate the shape. The view point of the evaluator is measured using LED marker and spherical mirror, and the projected reflection pattern is adjusted for the viewpoint adequately in realtime.
