摘要
通过双弧图像采集系统,在双弧平面、侧面进行拍摄,获取了清晰的双弧图像.通过图像处理和分析,发现采用形态学方法水域分割较常规方法更容易获取较为准确的电弧初始轮廓,同时针对电弧产生的丝絮状噪声,采用开运算进行处理,最后进行边缘提取,获得了较为准确的双弧轮廓.为DE-GMAW电弧特性深入研究打下基础.
Abstract
Adopting a double arc image acquisition system, the morphology on the side of double arc plane, distinct arc images were acquired. Watershed segmentation could acquire more accurate arc initial outline than conventional method through image processing and analysis, and due to filiform noise produced by arc, adopting the morphological opening operation, and the accurate double arc outline was extracted after edge extraction. The results could lay foundations for further study of DE-GMAW arc characteristic.
