| 摘 要： | 工程图自动识别系统中，首先遇到的问题是工程图的二值化，而二值化中关键的步骤是闽值的选取．根据工程图纸的特点，在众多闲值选取方法中选择逼近迭代闲值选取法作为处理方法，同时与Otsu算法和峰谷阈值算法作了分析和比较．试验结果显示逼近迭代闵值选取法既能提高处理效果又能提高处理速度．

| Abstract: | In the course of dealing with engineering drawing image, the binarization is the first problem to face, while the selecting threshold is significant in the binarization. According to the characteristics of Engineering Drawing, not all methods are adaptive. This paper select three common methods to try. The results of experiments indicate that the iteration is the best method. It can improve process speed and get the good result. |
