This work describes a method for filling holes in a 3D mesh based on 2D image restoration algorithms. Since these algorithms need an image as input, the first stage of the method concerns a 3D to 2D transformation. By projecting the 3D surface onto a squared plane, a 2D image is generated in such a way that the depth information is stored in each grid. The(More)
This paper deals with the generation of accurate, dense and coloured 3D models of outdoor scenarios from scanners. This is a challenging research field in which several problems still remain unsolved. In particular, the process of 3D model creation in outdoor scenes may be inefficient if the scene is digitalized under unsuitable technical (specific scanner(More)
In this paper we present a method for automatic segmentation of 3D complex scenes from a single range image. A complex scene includes several objects with: irregular shapes, occlusion, the same colour or intensity level and placed in any pose. Unlike most existing methods which proceed with a set of images obtained from different viewpoints, in this work a(More)
