Abstract(s)

In this paper we present efficient and fast algorithms for the reconstruction of scenes or objects using range image data. Assuming that a good segmentation is available, we concentrate on the polygonisation, triangulation and optimisation, i.e. both triangle reduction and adaptive edge filtering to improve edge linearity. In the processing, special attention is given to complex edge junctions. In a last step, vertex neighbourhoods are analysed in order to robustly attribute depth to the triangle list from the noisy range data.
