【摘要】 概述了一种基于D2分布图的三维CAD模型相似评价算法,在引入相关生活实例的基础上,课题以直方图算法和相似评价算法为核心.以模型获取→直方图计算→距离求值→相似度评定为主线索、以技术介绍→算法分析→优化评定为具体细节,最后得出两CAD模型的相似度并做出相似评定.更多还原

【Abstract】 This paper proposes and implements a 3D CAD model similarity assessment algorithm based the D2 distribution,and based on the life examples,this paper take the histogram algorithm and similarity assessment algorithm as the key toget model → histogram calculation → from the evaluation → similarity assessment of the main clues to technical presentations ? algorithms ? optimized for the specific details of the assessment.And finally we get the similarity and assessment.更多还原
