TOFD检测是利用超声衍射波来对工件进行检测,发现工件中的缺陷并对之进行精确定位,甚至定性,实际工作中由于工件的复杂性以及要求的多样性,图像变得非常杂乱,在分析的时候对经验和图像处理要求比较高,所以在很多的情况下需要利用其它软件或设备来提升图像的处理能力,以协助提高分析的便捷性,本文着重介绍TOFD图像的在机和脱机数据分析。 TOFD detection is the use of ultrasonic diffraction waves to detect the workpiece, found the workpiece defects and precise positioning, and even qualitative, the actual work due to the complexity of the workpiece and the diversity of the request, the image becomes very messy, in the analysis Experience and image processing requirements are high, so in many cases need to use other software or devices to enhance the image processing power to help improve the convenience of analysis, this article focuses on TOFD images of the machine and offline data analysis.
