| 摘 要： | 圆弧识别是工程图纸矢量化研究中的重点和难点.为了提高识别的效率和精度,本文提出了一种基于条形块跟踪的圆弧矢量化方法,该方法采取条形块跟踪的思想获取圆弧和组合线的低级矢量—型值链,对组合线进行了分割,在几何意义明显的圆弧型值链上,通过检测和验证的方法识别出圆弧.在实验中,分别用标准数据和真实图纸进行了测试,实验结果显示算法具有较高的识别精度和识别效率.

| Abstract: | Recognition for arcs is an important and difficult problem in the study on vectorization of scanned image of engineering drawings. This paper presents an algorithm for recognizing arcs using bar tracking, which acquires the points chains of arcs and combined lines using bar tracking, then the combined lines are segmented, at last the arcs are fitted and validated. In experiments, we test the algorithm using benchmark data and real drawings. The experiments indicate that the algorithm is fast and effective. |
