Calculation method of joint elongation of steel cord conveyor belt

  • 摘要: 针对钢丝绳芯输送带接头伸长判断方式单一、伸长量计算复杂度较高的问题,提出了基于X光图像的钢丝绳芯输送带接头伸长量计算方法。通过直方图均衡化和均值滤波对图像进行预处理,提高了图像对比度,有效解决了钢丝绳芯输送带图像灰度不均匀问题;利用Sobel算子进行接头边缘检测和动态阈值处理,提取上下接头;通过上下接头拟合直线斜率判断待检图接头和参考图接头是否一致,从而判断接头是否伸长;根据上下接头的端点和拟合直线计算接头左右端最外侧长度和接头平均长度。测试结果表明,该方法计算速度快、效率高,可以方便、准确地计算出接头伸长量。
    Abstract: In view of problems of single determination way and high computational complexity of joint elongation of steel cord conveyor belt, a calculation method of joint elongation of steel cord conveyor belt based on X-ray image was proposed. Histogram equalization and mean filter are used to pretreat image for improving image contrast and effectively solving the problem of uneven grayscale image of the steel cord conveyor belt. Sobel operators are used for joint edge detection and dynamic threshold process to extract upper and lower joints. Slope of fitting straight line of the upper and lower joints is used to determine whether the joint of the image to be checked is the same with the reference joint, so as to judge whether the joint is elongated or not. Outermost length on the left and right ends of the joint and average length of the joint are calculated according to the end points and the fitting lines of the upper and lower joints. The experimental results show that the method is computationally fast, efficient and can calculate the joint elongation easily and accurately.
