Abstract:
In this paper, we propose a method for emphasizing 3D shapes by using patterned light projection from multiple projectors. In this method, we project patterned lights from multiple projectors. Then, the patterned lights are mixed up at the surface of objects. As a result, object regions which are different from preregistered 3D shapes are colored and emphasized visually. In this method, we do not need any computation for image processing, since the image processing is achieved by mixing lights projected from multiple projectors. Furthermore, we do not need to find image correspondences in order to obtain 3D information of objects. In this paper, we propose a method for generating projection patterns for visualizing small difference in 3D shapes such as defects of shape. The efficiency of the proposed method is test by using multiple projectors.
