The paper presents a new scene analysis system that automatically reconstructs the 3D geometric model of real-world scenes from multiple range images. The reconstruction is achieved through a fully comprehensive procedure that includes range data acquisition, geometrical feature extraction, registration and integration of multiple views. A new hybrid algorithm for the segmentation of range images has been developed to overcome the particular problems specific to this kind of image. This algorithm combines edge and region detection approaches to build a high-level 3D description of a real scene described by a noisy range image. Another relevant issue is the registration/integration of range images from different viewpoints into a consistent 3D model. The integration part combines registered and partially overlapping data sets into a full high-level surface representation. Relevant experimental results from the complete 3D scene modelling are shown.
