摘　　要： 简要回顾了小波变换的发展历史 ,着重阐述了小波变换应用于弧焊过程的视觉信号图像处理 ,成功地解决了除噪、边缘检测和特征信息提取等关键技术 。 In this article, the history of wavelet transformation was reviewed briefly. It was expatiated in detail that some key-techniques such as avoiding the noise, detecting the edge and pick up of property information were solved owing to successful application of wavelet transformation in the image processing of arc-welding vision signal. And all the above key-techniques were validated through experiment.

关 键 词： 视觉信号 小波分析 弧焊 图像处理 信号处理 焊缝跟踪
