| 摘 要： | 为避免钢坯标号数字字符出现局部畸变、笔画断裂和粗细变化等现象,提出了一种新的基于改进模板匹配的在线实时识别方法.利用灰度面积滤波、改进二值化等图像处理技术滤除干扰,完成字符提取;通过投影法得到单个字符;引入隶属度概念,改进了经典模板匹配方法,以增强抗干扰能力.试验结果表明,该方法可行有效,稳定性和实时性均满足实际生产需要.

| Abstract: | To avoid local distortion,stroke break and thickness variation in steel billets characters,a real-time online identification system based on improved template matching was proposed.Through image processing technique including grayscale area filter,improved auto-threshold algorithm,noises were filtered and characters were extracted from the image.Single character was achieved by using projection function.Classical template matching technique was improved by membership assignment conception to recognize characters robustly.Experimental results proved the feasibility and effectiveness of the system.Stability and real-time performance of the method were catering to production requirements. |
