| 摘 要： | 提出了一种基于计算机图像处理的板形识别方法。首先对输入系统的图像进行中值滤波去噪预处理;再通过Canny算子检测图像的边缘;用Hough变换提取钢板板形特征;最后根据板形特征应用分类决策树实现对钢板板形的分类。实验表明该方法能有效地识别出钢板的单边浪、双边浪、中间浪和边中浪。

| Abstract: | A kind of technique for plate-profile recognition based on computer image processing is proposed.Firstly, the image is filtered out some noise using median filter;Secondly,the edge is detected by Canny operator;Thirdly, profiles and flatness features are selected by Hough transform;at last,according to the features,the plate-profile's classifying by decision tree is realized.Experiment shows that this method can recognize the plate-profile including unilateralwave,bilateral wave,center wave and both edge and center wave. |
