BAG结构在图形识别中的应用

The Application of BAG Structure in Drawing Recognition

BAG数据结构具有结点少，运算方便，便于遍历等特点，作者探索了一种基于BAG数据结构的线段和圆的识别方法，这种识别方法能以较少的数据量保留图的形状和网络特征，速度快，识别效果好，适于处理大幅面的工程图纸。

A set of experiment shows that the BAG structure is of less node, easier opera-tion, more convenient traversal. On the basis of the BAG structure, recognizing methods to lineand circles are presented, While chatacteristic of drawin are retained wih less data. of higherspeed, better correct recognizing ratios it's suitable for operating various engineering drawing.
