机器视觉检测在硬盘容器混料检测上的应用

硬盘容器的混料检测,一般是不能通过尺寸等进行检测的,因为常规的硬盘尺寸基本是一样的,如3.5寸、2.5寸的硬盘等,一般差别都是在容量和速度上。所以,尺寸是不可以作为判断标准的。而硬盘容器常用的类别判断,一般都是通过字符来进行区分的,今天我们就来聊一聊基于机器视觉的硬盘容器混料检测。

The mixture testing of hard disk containers is generally not detected by size, because the conventional hard disk size is basically the same, such as 3.5 inch, 2.5 inch hard disk, and the general difference is in capacity and speed. Therefore, size can not be used as a criterion. And hard disk containers commonly used category judgment, usually through the character to distinguish, today we talk about a chat based on machine vision of the hard disk container mixture detection.

对于这类产品,只需要将硬盘容器表面的字符表现出来,即可作为判断依据,进行混料的检测了。所以重点是用视觉检测设备将容器表面的字符表现出来。但是这些字符,并不一定都是容器的外表面,在外表相对要好照明一些,而有些字符会在容器内部,这样可用的光源类型就比较少了。至少很低角度的光源是无法使用的。所以只能考虑一些高角度的光源,如高角度的环形光源、同轴光源等。
For this kind of product, just need to show the characters on the surface of the hard disk container, can be used as a basis for judgment, to test the mixture. So the key is to use visual inspection equipment to display the characters on the surface of the container. But these characters, not necessarily the outer surfaces of the container, are relatively better illuminated in the appearance, and some of the characters will be inside the container, so the available light source type is less. At least a very low angle of light is unusable. So we can only consider some high angle light sources, such as high angle circular light source, coaxial light source and so on.

可以考虑使用常规的模拟控制器或者是迷你控制器。如果视觉检测设备在高速拍照需要很短的曝光时间,则考虑使用频闪控制器,而如果需要程序控制不同的光源亮度以适用不同的产品,则可以考虑数字控制器。
Consider the use of conventional analog controllers or mini controllers. If a visual inspection device takes a short exposure time at high speed, a strobe controller is used, and a digital controller can be considered if the program is required to control different light sources for different products.

因为字符相对比较大,所以使用30万像素或130万像素的CCD工业相机即可满足要求。可以考虑使用千兆网CCD工业相机,性能完全可以满足要求,价格也非常亲民。工业镜头可以使用常规的镜头进行拍摄,即可获得较好的效果。配好了以后,基于机器视觉的硬盘容器混料检测设备可以快速的检测出不合格的产品,大幅提高了工作效率和工作质量。
Because the characters are relatively large, the use of 300 thousand pixel or 1 million 300 thousand pixel CCD industrial cameras can meet the requirements. We can consider the use of Gigabit Ethernet CCD industrial cameras, the performance can completely meet the requirements, the price is also very close to the people. Industrial lenses can be photographed using conventional lenses, and good results can be obtained. After matching, the hard disk container detection equipment based on machine vision can quickly detect the unqualified products and greatly improve the work efficiency and the quality of work.
