Application of Image Technique in The Detection of Pipeline Welding Cracks

在管道焊接过程中,利用图像处理法可得到大量的焊接裂缝图像信息与特征信息。可通过对焊接裂缝信息的检测,从而实现在焊接过程中对焊接裂缝质量的实时控制。针对在管道焊接过程中容易造成焊接微小裂缝这一问题,提出了一种基于图像处理法的管道焊接裂缝检测系统。系统主要包括激光器、CCD摄像机、图像采集卡、计算机图像处理软件等。通过实验研究表明,该系统有协调能力好、抗干扰能力强、控制精度高,性价比高等优点。

In the process of pipeline welding,a large number of image information and feature information can be obtained by image processing. Through the detection of welding crack information,so as to realize the real-time control for the quality of welding cracks in the welding process. In this paper,a new method based on image processing is proposed to detect the cracks in the welding process. The system mainly includes laser,CCD camera,image acquisition card and computer image processing software. The experimental results show that the system has the advantages of good coordination ability,strong anti-interference ability,high control precision and high cost performance ratio.
