基于Canny算子的滤棒数量检测方法

Counting method for filter rods based on Canny operator

为解决生产中无法精确统计滤棒数量等问题,提出了一种基于Canny算子的滤棒数量检测方法。该方法利用图像处理技术,通过Canny算子对整个托盘的滤棒进行边缘检测,再利用图像形态学中的膨胀运算增加检测边缘的清晰度,同时结合滤棒圆形特性精确定位滤棒位置,实现滤棒数量检测。以长支烟、中支烟和短支烟滤棒样品为对象进行测试,结果表明:该检测方法能够实现滤棒数量的精确统计,准确率达到99.27%,且适用于检测各种圆周滤棒,具有较好的通用性和鲁棒性。该方法可为降低滤棒材料消耗提供技术支持。

To make an accurate count in filter rod making,a method was proposed based on Canny operator and image processing technology through edge detection of all filter rods in a tray with Canny operator,and by means of the dilation operation in image morphology to increase the definition of the detected edges.At the same time,the positions of filter rods are accurately located according to their circular profiles and further their number is determined.The filter rods of different lengths were counted with the proposed method,the results showed that this method could count the number of filter rods accurately with an accuracy of 99.27%,it also showed good adaptability and robustness capable for counting filter rods of various circumferences.This method provides a technical support for reducing the consumption of filter material.
