A Reverse Engineering method for 3d parametric modeling of geometries based on processing of laser scanning data and a sweep technique

[摘要] A Reverse Engineering (RE) method for parametric modelling is presented in this paper. According to this method laser scanning data are processed by means of an algorithm and a parametric geometry is produced. The algorithm generates a spline used as a driving curve for a 2D profile, both approximated from the point cloud data, with the final geometry being produced through with a sweep based technique. The method was applied to digitize a commercial product, a bottle, and the geometry was reconstructed at high accuracy and surface quality. Finally the results of the proposed method were compared with auto surfacing from ∗.stl files and with surfaces generated by means of sweep commands without converting curves to splines.
