摘要

摘要：针对镁合金双弧焊多聚焦熔池图像融合规则的选择，提出了基于窗口化小波低频系数的融合规则.该融合规则考虑了低频分量对融合后图像的贡献和图像像素间的相关性.由实验结果及客观评价数据表明，该算法能够得到较好的融合效果，增加了镁合金双弧焊多聚焦熔池图像中的清晰目标和融合熔池边缘信息.

Abstract：

Abstract： Aimed at the selection of the multi-focus image fusion rule of double arc welding of magnesium alloy, a fusion rule was proposed based on windows for choosing wavelet low frequency coefficient. The fusion rule gave full consideration of the contribution of the low frequency component to the fused image and the correlation between image pixels. To the experimental results and objective evaluation indicates that the proposed algorithm can have a better fusion effect, a clear object and fusion pool edge information of the multifocus image fusion of double arc welding of magnesium alloy.
