摘要
针对现有输送带纵向撕裂检测方法存在敏感度低、操作不便、非可视化等问题,提出了一种基于Hough变换的输送带纵向撕裂检测方法。该方法使用线光源辅助照射,利用CCD实时采集输送带下表面图像,通过Hough变换提取图像斜率差特征来判断输送带是否发生纵向撕裂。测试结果验证了该方法的有效性。
In view of problems of low sensitivity,inconvenient operation and non-visualization of existing detection methods of conveyor belt longitudinal tear,a detection method of conveyor belt longitudinal tear based on Hough transform was proposed.Lower surface image of conveyor belt is collected in real-time by use of CCD with line light source as auxiliary irradiation,and slope difference characteristics of the image are extracted through Hough transform,so as to determine whether longitudinal tear of conveyor belt happens.The test result verifies effectiveness of the method.
