Abstract

Abstract: In order to improve the fitting quality, firstly, contours are extracted from scanning data points to fit Fourier series, then unit tangent and binormal can be got at any point based on Frenet frame of curve theory, and the objective function of fitting quality referencing Hausdorff distance can be constructed. The global optimal transform parameter can be found based on differential evolution. Effectiveness of the method is demonstrated by one practical door-fitting example. Results indicate that the proposed method can significantly improve the fitting consistency and improve automobile dimension quality.
