  机器视觉检测系统凭借速度、精度和可重复性等优势,擅长于对结构化场景进行定量测量,能够轻松检验小到人眼无法看到的物品细节特征,还能够防止洁净室受到人为污染,也能让工人免受危险环境的威胁。
  With the advantages of speed, accuracy and repeatability, machine vision detection system is good at quantitative measurement of structured scenes. It can easily check the details of objects that are too small for human eyes to see. It can also prevent the clean room from being polluted by human beings and protect workers from the threat of dangerous environment.
  在现代工业自动化生产中,机器视觉检测系统涉及各种检查,测量和零件识别应用,例如汽车零件尺寸检测、自动装配完整性检测,电子装配线自动零件定位、饮料瓶盖印刷质量检测、产品包装上的条形码和字符识别等。此类应用的共同特征是连续大批量生产以及对外观质量都有很高的要求。
  In modern industrial automation production, machine vision inspection system involves a variety of inspection, measurement and parts identification applications, such as automobile parts size detection, automatic assembly integrity detection, electronic assembly line automatic parts positioning, beverage bottle cap printing quality inspection, product packaging bar code and character recognition, etc. The common characteristics of such applications are continuous mass production and high requirements for appearance quality.

  通常,这种高度重复和智能的工作是由肉眼完成的,但是在某些特殊情况下,例如精确快速地测量微小尺寸,形状匹配和颜色识别等,肉眼无法持续稳定地进行,也很难用其他物理量传感器来执行。
  Usually, this kind of highly repetitive and intelligent work is completed by the naked eye, but in some special cases, such as accurate and rapid measurement of micro size, shape matching and color recognition, the naked eye can not continuously and stably carry out, and it is difficult to implement with other physical quantity sensors.
  随着行业竞争的加剧,公司对产品质量的控制甚至不允许出现0.1%的缺陷,因此必须保证100%的检验合格率(即“零缺陷”)以确保业绩的持续稳定的增长。
  With the aggravation of industry competition, the company does not even allow 0.1% defects in product quality control. Therefore, it is necessary to ensure 100% inspection pass rate (i.e. "zero defect") to ensure the continuous and stable growth of performance.
  使用CCD摄像机捕获图像并将其发送到计算机或专用图像处理模块,通过数字处理,可以根据像素分布,亮度和颜色等信息确定大小,形状和颜色。
  CCD camera is used to capture the image and send it to the computer or special image processing module. Through digital processing, the size, shape and color can be determined according to the pixel distribution, brightness and color.

  这种方法将计算机处理的快速性和可重复性与人类视觉的高度智能化和抽象的能力相结合,从而产生了机器视觉检测技术的概念。
  This method combines the rapidity and repeatability of computer processing with the highly intelligent and abstract ability of human vision, thus producing the concept of machine vision detection technology.
  机器视觉检测技术是一种基于计算机视觉研究的新兴检测技术。与计算机视觉研究不同,视觉检测技术着重于物体几何形状的测量和位置测量,例如汽车车身的三维尺寸的测量等。测量大型工件的同轴度和共面性。
  Machine vision detection technology is a new detection technology based on computer vision research. Different from the research of computer vision, vision inspection technology focuses on the measurement of geometric shape and position of objects, such as the measurement of three-dimensional dimensions of automobile body. Measure coaxiality and coplanarity of large workpiece.
  此外,机器视觉检测系统技术的检测系统还可以自动检测整个产品,这对于控制产品品质和确保产品质量也非常重要。
  In addition, the detection system of machine vision inspection system technology can also automatically detect the whole product, which is also very important to control the product quality and ensure the product quality.
