摘　　要：多边形的骨架线其本质是对多边形的抽象描述,合理的提取多边形的骨架线能够准确描述多边形的形态。给出了内侧缓冲区算法的定义及特性,提出利用内侧缓冲区算法提取多边形骨架线的模型,并给出了提取骨架线的实验。The polygon skeleton is the abstract description of polygon.Finding the skeleton reasonably can describe the polygon more accurately.The definition and character of inner buffering algorithm were present in this paper.The model of finding polygon skeleton was present by using inner buffering algorithm,as well as the experiment of finding polygon skeleton was made.

关 键 词：骨架线 多边形 缓冲区算法
