摘　　要：焊缝边缘是焊缝图像的最主要特征,选用适当的边缘检测算子得到准确的焊缝信息是焊缝图像的关键步骤。选用Canny算子,提出了一种基于OpenCV的焊缝图像边缘检测方法。将开放源代码的OpenCV作为开发焊缝图像边缘检测程序的基础函数库,开发焊缝图像边缘检测程序,从而解决了焊缝图像边缘检测程序开发周期长、效率低的缺点。Weld edge is the most important characteristic in a weld image.Selecting an appropriate edge detecting operator to get the accurate weld edge information is a key process in weld image processing.Canny operator is selected and a method for edge detection of weld image based on Intel＇s Open Source Computer .Vision Library（OpenCV）is proposed.The OpenCV can be used as a basic fimction library of developing application program of edge detection of weld image.This method can solve the disadvantage of long period and low efficiency for developing apphcation program of edge detection of weld image.
