| 目的 提出一种基于视觉图像处理的直管段端面圆边缘检测算法与装置，用于直管段精确计数，以提高计数精度和包装效率。方法 使用CCD采集直管段端面图像，在Matlab软件中编写检测算法，分别通过对像素坐标、阈值大小的调节来增强图像的对比度，完成图像的灰度化、二值化预处理。将霍夫变换与Harris Laplace算法相结合，并对管段端面进行边缘检测；通过设定管径大小实现端面圆形边缘的识别、显示与计数。结果 将直管段放入设计的视觉计数装置中，通过可动挡板使端面对齐后，采用图像处理技术来实现视觉计数，多次测试结果验证了系统的正确性。结论 该方法可以用于直管段的自动计数。 |
| 英文摘要: |
| This article aims to proposea circular edge detection algorithm based on visual image processing for the accurate counting of straight pipes, so as to improve the counting accuracy and packaging efficiency.CCD was used to collect the end image of straight pipe, and the detection algorithm was written in Matlab software. The contrast of the image was enhanced by adjusting the coordinates of the pixels and the size of the threshold, and the gray and binary preprocessing of the image werecompleted. Hough transform and Harris Laplace algorithm werecombined to detect the edge of the end surface of the pipe. The circular edge of the end surface was recognized, displayed and counted by setting the diameter of the pipe. The straight pipes wereput into the designed visual counting device. After the end section was aligned by the movable baffle, the visual counting was realized by image processing technology. The correctness of the system was verified by many test results. This method can be used for automatic counting of straight pipe sections. |
