线段豪斯多夫距离度量下的车身覆盖件匹配方法

Method of Autobody Closure Panels Fitting Based on Line Segment Hausdorff Distance

摘要:

引入线段豪斯多夫距离(line segment Hausdorff distance,LHD)作为匹配质量度量，建立基于特征点集合的覆盖件匹配模型，基于遗传算法快速并行搜索匹配形位变量，确定最佳匹配调整参数.某发动机罩匹配的实际应用表明,该方法能有效提高车身匹配质量.

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.

Key words:line segment Hausdorff distance; closure panels; best fitting
