机器视觉检测在金属表面缺陷检测领域的应用

  • 更新日期 - 2019年10月17日 05:34

基于机器视觉检测的金属表面缺陷检测设备经过一系列的图像处理算法,可以识别金属卷材、带材表面的缺陷,如常见的辊印、划痕、锈痕、羽纹、粘结、折印等,广泛应用于钢铁、有色金属,有助于减少漏检发生率,提高了产品的质量,使冶金带钢的生产管理者彻底摆脱了无法全面掌握产品表面质量的状态。

After a series of image processing algorithms, the metal surface defect detection equipment based on machine vision detection can identify the defects of metal material and strip surface, such as common roll print, scratch, rust mark, feather grain, bonding and folding printing, which are widely used in steel and non-ferrous metals, which can help to reduce the incidence of leakage and increase the rate of leakage. The quality of the products has made the managers of metallurgical strip completely get rid of the state that the surface quality of products can not be fully grasps.

机器视觉检测在金属表面缺陷检测领域的应用机器视觉检测设备

它的工作原理是采用高速CCD工业相机对板材表面进行实时拍照,照片经数字化处理后,送入主机进行图像处理,通过参数计算,对板材图片提取特征老板办公室噗嗤好爽,以检测表面缺陷信息,然后进行分类定等级。

The principle of it is to take a high-speed CCD industrial camera to take real time pictures on the surface of the plate. After the digital processing, the picture is sent to the host for image processing. Through the calculation of the parameters, the characteristics of the sheet images are extracted to detect the information of the surface defects, and then the classification is classified.

其次,利用视觉检测设备以数字的形式对信号进行采集、滤波、检测、均衡、去噪、估计等处理,从而得到符合需要的信号形式,包括图像变换,图像编码,图像增强,图像恢复,图像分割,图像理解,识别系统等。

Secondly, the signal is collected, filtered, detected, balanced, de-noised and estimated in the form of a number of visual detection devices, so as to get the form of signal that meets the needs, including image transformation, image coding, image enhancement, image restoration, image segmentation, image understanding, recognition system and so on.

基于机器视觉检测的金属表面缺陷检测设备可用于冷轧板、酸洗板、汽车钢板、不锈钢板、彩钢板、镀锌板、镀锡板、镀金板、 有色金属带材及各类复合带材卷材表面质量检测。广泛安装于冷轧线、开卷线、分卷线、钢板配送中、其它金属材料材生产加工线等领域。

Metal surface defect detection equipment based on machine vision detection can be used for the surface quality testing of cold rolled plate, pickling plate, automobile steel plate, stainless steel plate, color plate, galvanized plate, tin plate, gild plate, nonferrous metal strip and all kinds of composite strip materials. It is widely installed in cold rolling line, uncoiling line, dividing line, steel plate distribution, other metal material production and processing line and other fields.
