管道焊缝缺陷图像特征参数的提取

Extraction of Pipe Weld Defect Image Feature Parameter

焊缝的质量直接影响管道的使用寿命.有效检测出焊缝的缺陷,具有十分重要的现实意义和经济价值.本文介绍了焊缝图像缺陷特征参数的提取方法,为管道焊缝缺陷识别与评价奠定了基础,为管道焊缝质量控制和缺陷检测提供技术保障.

The quality of line is directly affects the pipeline life. It has the important realistic meaning and economic value to effectively detect the welding. This paper introduces the extraction method of the welding image feature parameter and laid the foundation for the identificatiori and evaluation of pipe weld defects and provided technical support for the pipe weld quality control and defect detection.
