基于AHP层次分析法的2D车身草图特征线权重分析

Feature Weight of 2D Sketching for Auto Styling Based on AHP

针对2D草图中出现的主要特征线进行层次实验分析(AHP),应用统计学方法构造车身各种造型特征线的层次结构,并根据特征线在绘图时的重要程度建立判断矩阵,求解其特征向量和最大特征值,并根据特征向量对其权重进行排序并进行一致性检验。通过本文的实验分析,为应用三维手绘系统快速建立2D草图,实现2D到3D一体化无缝数字建模奠定研究基础。

In this paper,experimental method of analytic hierarchy process（AHP）based on statistics has been used to analyse the feature weight of 2D sketching for auto styling.In AHP,the feature of car body has been arranged into a hierarchic structure,and paired comparisons with each other in order to construct pairwise comparison matrix.The consistency of the matrix data is defined and measured by eigenvector and the largest eigenvalue.The experimental results reveal the research base of integration digital modeling of car from 2D to 3D.
