摘　　要：基于点云重构曲面的过程,曲面分面依赖设计人员经验,为了提高A级曲面开发的效率,本文提出了主曲面可变模型方法,作为标准化的面片结构模型。针对不同车型的点云模型,只要输入相应尺寸值,得到与点云模型匹配的主曲面模型。运用以上构建方法,可以有效减少曲面的准备时间,降低了设计者对建模熟练度的要求,可缩减15%的A级曲面开发时间。In the process of reconstructing the surface based on the scan data,the surface reconstruction depends on the experience of the designer.In order to improve the efficiency of the A-Class surface development,this research proposes a variable model method for the main surface as a standardized patch structure model.For the scan data of different models,as long as the corresponding size value can be input,the main surface model matching the scan data model can be obtained.Using the above construction method can effectively reduce the preparation time of the surface,reduce the designer's requirement for modeling proficiency,and reduce the development time of A-Class surface by 15%.
