| 摘 要： | 分析研究了弧焊熔池视觉传感方法。针对射流过渡熔池，分别采用405nm和1064nm窄带滤光片组成的复合滤光系统取得了各自的熔池图像，比较发现采用1064nm的复合窄带滤光系统取得了清晰的熔池图像。分析了射流过渡熔池图像特征，基于该特征，通过高斯滤波、灰度拉伸和边缘检测等计算机图像处理技术，获得了清晰、连续的熔池轮廓。

| Abstract: | This article analyzes sensing method of arc welding pool. With respect to spray transfer pool, compound filters system composed of 405nm or 1065nm narrow band filer are used, and respective pool images are obtained. Compared with each other, more clear pool image can be found through filter set composed of 1064nm narrowband. Characters of spray transfer pool are studied. Based on these characters,through computer image processing such as Gauss filter, gray stretch, border detection etc., a clear and sequential pool contour is acquired. |
