摘　　要：针对无固定起点、无精确尺寸、无统一比例的平面矢量图形,提出一种相似性比较识别方法。首先提取单个图素的属性特征以及图素之间的位置关系、拓扑关系特征,这些特征因素具有不同层次,而且有模糊性,因此采用三级综合模糊评判方法来评判相似识别结果。该方法易于构造,便于软、硬件实现,并成功应用于工科作业图形的批改识别中。For those plane vector graphics with no fixed starting point,no precise size and no uniform proportion,a similarity comparison identification method is proposed. Firstly,we extract the property characteristics of individual graphic elements as well as the characteristics of location relations and topological relations between those elements. Since these feature factors have different hierarchies,and also have strong ambiguity,therefore we then apply the three-stage comprehensive fuzzy evaluation method to judge the results of similarity recognition. The method is easy to form,convenient to be implemented by hardware and software,and has been applied to marking and recognising the graphics assignments of engineering courses successfully.
