METHOD FOR ACQUIRING THREE-DIMENSIONAL OBJECT BY USING ARTIFICIAL LIGHTING PHOTOGRAPH AND DEVICE THEREOF

Abstract

Disclosed are herein a three-dimensional (3D) object acquisition method and an object acquisition apparatus using artificial light photographs. A 3D object acquisition method according to an embodiment of the present invention includes receiving a plurality of images of a 3D object photographed by a camera, reconstructing spatially-varying bidirectional reflectance distribution functions for the 3D object based on the plurality of images received, estimating shading normals for the 3D object based on the reconstructed spatially-varying bidirectional reflectance distribution functions, and acquiring 3D geometry for the 3D object based on the estimated shading normals.
