| Abstract: | Line segment Hausdorff distance (LHD) is used to measure the degree of matching effect to improve fitting quality and the conception of Points Hausdorff Distance fitting is developed. New panel fitting model is presented and Genetic Algorithm is used for parallel searching fitting parameters. A case study of auto-body engine hood fitting design shows that the proposed method can effectively improve fitting quality. |
