In reverse engineering, 2D profile curve reconstruction based on cross-sectional points is a very crucial step for surface reconstruction such as lofting surface, swept surface, translational surface, and rotational surface. Unlike the traditional constrained fitting method that assumes that the cross-sectional points have been segmented in advance, and that the initial fitted curves are very close to the points, we propose a nonrigid registration method, through which a template curve can be automatically transformed and deformed to best fit the cross-sectional points. Compared with constrained fitting, nonrigid registration does not need any data preprocessing such as sorting, segmentation, and parametrization. The simulated and real examples have demonstrated the effectiveness and superiority of nonrigid registration for 2D blade profile curve reconstruction.
