基于数字图像处理的光切法槽深测量方法研究

Research on a fathoming method for groove based on light-section and digital image processing technique

在窄浅槽的深度测量方面,常用的测量方法受到很多的限制。对不锈钢管的电火花加工(EDM)的刻槽深度测量,提出了一种在光切法基础上采用电荷藕合器件图像传感器(CCD)获得不锈钢管表面和刻槽底部的图像,运用数字图像处理技术对图像进一步处理的刻槽深度测量方法。介绍了光切法的原理,并详细介绍了对所获得的数字图像进行处理的步骤。实际应用表明,该方法有较高的测量精度。

Normal methods are restrained to measure the depth of narrow and shallow groove. With dealing with the photographed images of the tube＇s surface and the groove＇s bottom, a method was put forward to fathom the groove cut on stainless steel tube by EDM, based on light-sectioning method and digital image processing technique. Introduction included the principle of light-sectioning method and steps of processing the digital images were given
