全变分法恢复焊缝磁光图像质量分析
|
摘要
在利用磁光传感器检测焊缝位置时,因为受到试验环境的影响,采集的焊缝图像会出现图像降质现象,对微间隙焊缝进行准确检测造成困难,因此需对焊缝磁光图像进行图像恢复处理。采用全变分法图像恢复模型,分析图像恢复质量,结果表明,此模型能在降噪的同时,保持焊缝图像良好的细节特征。
In the process of magneto-optic imaging system to detect weld position,due to the test environment is not stable,detection process are influenced by the light intensity and image background noise. The magneto optical sensors to collect the weld image will appear drop phenomenon,to accurately detect the difficulties of micro weld gap,therefore need to weld magneto-optic image for image restoration processing. With the variational method to restore weld magneto-optic image quality is analyzed. Using variational method of image restoration model noise reduction at the same time,keep the good weld image details.
