Abstract: This paper introduces a coarse-to-fine algorithm for 3D registration that uses an alternative 3D Shape Representation: CIRCON (Cylindrical Image of Radial CONtours). Two point clouds can be aligned using their corresponding circon images for searching for correspondences. In order to accelerate this search, a coarse-to-fine approach based on wavelet image decomposition will be applied to the circon images. This permits to reduce, for each resolution level, the amount of indexes to be evaluated. The information obtained by the surface matching process is then used for calculating a coarse transformation (translation and rotation) between both surfaces; in such a way that two point clouds whose relative pose is unknown can be aligned.
