Abstract

We developed a direction system of real-world operation from distant site. The system consists of several sets of cameras, projectors and PCs connected via network each other. At first, the 3-D shape of the object is measured using pattern light projection method, and it is sent to the distant PC. A supervisor can observe the CG of the object from any viewpoint and draw annotation figures on the CG. The direction message is sent to the real field and projected onto the object using projectors. The projected annotations are well aligned geometrically because the all cameras and projectors are calibrated with single reference object. The worker is free from any wearing equipment, ex. HMD, and multi projectors avoid the problem of occlusion by the worker body. Direction of alignment task of both existing and new object are also implemented.
