基于数学形态学的激光拼焊熔池图像处理研究

基于拼板激光焊接工程中的实时检测系统,应用数学形态学中的相关图像处理技术,提出了一种新的熔池图像处理流程模型,并通过实验得到了三种清晰的熔池边缘图像,同时验证了该模型的正确性。将算法与经典算法进行比较,证明了该算法对于激光拼焊的适用性和鲁棒性。

The basic principles of image processing in mathematical morphology are summarized.A new flowchart model for image processing of weld pool is proposed,which uses the principles of the inspection and monitoring sys- tem in tailored welded blanks.Furthermore,three clear weld pool edge images were detected well in experiments. Experimental results show that the new method obtains not only perfect edge detection result but also good robustness to noise in TWB.Compared with other well-known edge detection algorithms,this technology performs favorably and can be used widely in TWB.
