Procedure-based component and architecture modeling from a single image

摘要

This paper advocates a new component-aware framework to reconstruct 3D architecture from a single image. Different from existing work, our motivation is to obtain a complete set of semantically correct 3D architectural components, which enables part reusability towards rapid model reproduction and facilitates model variation. The core of our system is a novel algorithm to adaptively segment repeated curved stripes (e. g., roof tiles, building floors) into individual elements, based on which 3D dimensions as well as architectural components are derived from a single image. Specially for Chinese architectures, we further devise an interactive method to identify outer columns based on userspecified inner columns. Finally, 3D components are generated and shape rules are derived, from which the buildings and their variants are constructed. Our newcomponent-aware framework minimizes the use of data resource (i. e., one single image) and emphasizes component utility during rapid 3D architecture reproduction by advocating a component-aware approach.
