摘　　要：利用正交设计方法对焊缝识别算法进行参数优化,以线性滤波、二值化、边缘提取法和宽度识别法为因素因子,对各因素的影响因子进行分析,分辨出各因素对识别焊缝宽度的主次关系。通过正交设计的极差和方差分析,得出焊缝识别算法的最优解,并对各因素间的交互作用进行系统地分析,确定因素间的相互作用对试验结果的影响程度。试验结果表明,正交设计方法适用于焊缝图像处理与识别领域,能够为焊缝识别算法的优化提供正确的分析标准。Factor optimization in weld recognition was studied based on the method of orthogonal design.Systemicevaluation and analysis of linear filter,threshold,edge detection and width calculation were carried out,aiming tofind out their primary-secondary relationship concerning weld recognition.The optimized method for weld calculationwas worked out based on range analysis and variance analysis.An objective evaluation was given on the interaction ofthe factors involved to study its influence on the results of experiment.It was shown that the orthogonal design methodwas applicable to weld image processing and recognition,as it could work out objective analysis and evaluation forweld recognition.
