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

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.
