MATEUS, Sandra P. Regularization Method of Quadrilaterals Mesh for 3D Object Reconstruction. Inf. tecnol. [online]. 2008, vol.19, n.4, pp.89-95. ISSN 0718-0764.

A regularization method of a quadrilateral mesh by means Geodesics and B-Splines, applied to 3D objects reconstruction, is proposed. The procedure can be summarized in three main steps: i) selection of quadrilaterals; ii) regularization of quadrilaterals and generation of points using B-Splines; and iii) matching regularized points by means of Fast Marching Method geodesic (FMM).  In the process of experimentation, the regularization of the representation of the quadrilateral mesh and the representation of the computational models were done with a range image of the cultural object moai. Despite having an irregular arbitrary topology, the proposed method gave adequate results in the conservation of the fine detail of the object.

Keywords : 3D objects; quadrilateral mesh; B-Spline; geodesic; regularization method.
