A major problem in reverse engineering is that the measured points having an irregular format and unequal distribution are difficult to fit into a B-spline curve or surface. The paper presents a method for pre-processing data points for curve fitting in reverse engineering. The proposed method has been developed to process the measured data points before fitting into a B-spline form. The format of the new data points regenerated by the proposed method is suitable for the requirements for fitting into a smooth B-spline curve with a good shape. The entire procedure of this method involves filtering, curvature analysis, segmentation, regressing, and regenerating steps. The method is implemented and used for a practical application in reverse engineering. The result of the reconstruction proves the viability of the proposed method for integration with current commercial CAD systems.: Springer-Verlag London Limited, 2000 Keywords: Curve fitting nationallicence Pre-processing of data points nationallicence Reverse engineering nationallicence Huang Ming-Chih Department of Mechanical Engineering, Tatung University, Taipei, Taiwan, TW aut Tai Ching-Chih Department of Mechanical Engineering, Tatung University, Taipei, Taiwan, TW aut https://doi.org/10.1007/s001700070033 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s001700070033 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Huang Ming-Chih Department of Mechanical Engineering, Tatung University, Taipei, Taiwan, TW aut NATIONALLICENCE 700 1- Tai Ching-Chih Department of Mechanical Engineering, Tatung University, Taipei, Taiwan, TW aut Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
