摘　　要：在空间的综合简化过程中,需要删除部分三维模型,笔者提出了一种基于NEMD的视觉相似度评价方法。该方法首先基于最小包容盒提取空间中单个模型的几何特征(长、宽、高),再分析模型之间的关系(距离),从而生成空间特征关系图(Attribute Relation Graph)。通过计算原空间与简化后空间特征关系图之间的嵌套运土者距离(NEMD),对模型场景之的视觉相似度进行评价。通过与用户实验的比较,本方法更符合视觉特征。In the process of comprehensive simplification of space,some 3d models need to be removed,and a visual similarity evaluation method based on NEMD is proposed in this paper.This method firstly based on the minimum contain the geometrical characteristics of the extraction of single model in space(length,width and height),then the relationship between the analysis model(distance)to generate space feature relation graph(Attribute function Graph).The visual similarity of the model scene is evaluated by calculating the distance between the original space and the embedded carrier distance between the simplified spatial feature diagrams.Compared with the user experiment,this method is more visual.
