| 摘 要： | 通过对点状地图符号特点及其识别难度的分析，提出了结构分析为主要识别方法，在结构分析中用模糊编号算法对组成符号的基元进行编码，有效地表示出基元的空间位置关系，大大消除了细化和轻微旋转对提取基元的影响，从而提高了识别率。

| Abstract: | After the characteristics of point shaped symbols and its recognition difficulty are analyzed, an automatic recognition method using structure analysis mainly is presented in this paper. In structure analysis, fuzzy coding algorithm is used to the coding of basic strokes which compose symbols. It shows the spatial located relation of basic strokes efficiently and reduces the inference of thinning and light rotation for recognition to a great extent, thus improving the recognition efficiency. |
