Coal piling detection of coal transport belt of power plant based on vision measurement

针对现有输煤胶带系统采用堆煤传感器检测胶带堆煤状态,存在误报和摩擦生电等问题,提出了基于视觉测量的非接触式胶带堆煤检测方法。该方法利用视觉检测中的单目视觉技术构建小孔成像测距模型,实现了胶带堆煤检测。实验结果表明,该方法具有实时性高、检测效果好等优点,堆煤检测准确性在95%左右,符合设计要求。

In view of problems of false alarming and triboelectrification existed in existing coal conveying belt system with coal piling sensor to detect state of coal piling of belt,a non-contact detection method of coal piling of belt based on vision measurement was proposed.The method uses monocular vision technology in visual inspection to construct small hole imaging model,and can measure coal piling of belt.The experimental results show that the method has advantages of high real-time property and good detection effect with detection accuracy of about 95%,which complies with design requirements.
