摘要
针对MAG焊缝熔池区域图像的特点,利用滤波处理、图像分割和图像形态学等熔池图像的基本处理方法,开发出具有较高适应性和鲁棒性的图像处理方法。采用基于方向小波的边缘提取和基于活动轮廓模型的方法,更适合对焊缝熔池和间隙进行边缘提取。
Aimed to the image features of MAG weld molten pool areas,the basic molten pool image approach such as filtering,image segmentation and image morphology,had been utilized to develop image processing method possessing of high adaptability and robustness.It was more suitable for the weld molten pool and the gap edge extraction by the method of directions wavelet and active contour model.These methods could filter out some disturbance in molten pool image and could effectively get the molten pool edge.
