A method for reconstructing a complete three-dimensional (3D) voxel model from multiple images captured during two circular motions of an object is proposed. The two circular motions include the object with a regular orientation and the corresponding reversed orientation. The shape-from-silhouette method, which constructs a voxelbased 3D model from the silhouettes of two-dimensional (2D) images, is used for the reconstruction. In general, a single camera focused on an object's circular motion cannot capture the entire object using a single fixed orientation. Thus, it is required to invert the orientation of the object at least once to capture the entire object. In this paper, a novel method for integrating two incomplete reconstructed voxel models to produce a single complete voxel model is discussed. Complex examples are provided to demonstrate the effectiveness of the proposed algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
