Abstract
This paper addresses the problem of obtaining complete, very detailed re constructions of shiny objects such as glazed ceramics. We present an algorithm which uses silhouettes of the ob ject, as well as images obtained under changing illumination conditions. In contrast with previous photometric stere o techniques, ours is not limited to a single viewpoint but produces accurate reconstructions in full 3D. A n umber of images of the object are obtained from multiple viewpoints, under varying lighting conditions. Starting fro m the silhouettes, the algorithm recovers camera motion and constructs the object’s visual hull. This is the n used to recover the illumination and initialise a multi-view photometric stereo scheme to obtain a closed surface reco nstruction. The algorithm has been implemented as a practical model acquisition system. Here, we present a number of complete reconstructions of challenging real objects.
