Abstract: Shape analysis of a three-dimensional (3-D) scene is an important issue and could
be widely used for various applications: city planning, robot navigation, virtual tourism, etc. We
introduce an approach for understanding the primitive shape of the scene to reveal the semantic
scene shape structure and represent the scene using shape elements. The scene objects are
labeled and recognized using the geometric and semantic features for each cluster, which is
based on the knowledge of scene. Furthermore, the object in scene with a different primitive
shape could also be classified and fitted using the Gaussian map of the segmented scene. We
demonstrate the presented approach on several complex scenes from laser scanning. According
to the experimental result, the proposed method can accurately represent the geometric
structure of the 3-D scene. © 2013 Society of Photo-Optical Instrumentation Engineers (SPIE).
