工业自动化为什么需要机器视觉检测技术

所谓机器视觉检测,就是用机器代替人眼来做测量和判断。是指通过机器视觉产品将被摄取目标转换成图像信号,传送给专用的图像处理系统,根据像素分布和亮度、颜色等信息,转变成数字化信号;图像系统对这些信号进行各种运算来抽取目标的特征,进而根据判别的结果来控制现场的设备动作。
The so-called machine vision detection, is to use the machine instead of the human eye to do measurement and judgment. It refers to the conversion of the intake target into an image signal through the machine vision product, transmitted to the special image processing system, according to the pixel distribution and brightness, color and other information, into the digital signal, the image system carries out various operations to extract the characteristics of the target, and then according to the results of the discrimination to control the field equipment action.

精确性和重复性,由于人眼有物理条件的限制,在精确性上机器有明显的优点。即使人眼依靠放大镜或显微镜来检测产品,机器仍然会更加精确,因为它的精度能够达到千分之一英寸。机器可以以相同的方法一次一次的完成检测工作而不会感到疲倦。与此相反,人眼每次检测产品时都会有细微的不同,即使产品时完全相同的。

Accuracy and repeatability, due to the limitations of physical conditions in the human eye, the machine has obvious advantages in accuracy. Even if the human eye relies on a magnifying glass or microscope to detect the product, the machine will still be more accurate because it can reach an accuracy of 1 per thousand inches. The machine can complete the inspection work once at a time in the same way without feeling tired. In contrast, the human eye is slightly different every time a product is detected, even if the product is identical.

速度和成本,机器能够更快的检测产品。特别是当检测高速运动的物体时,比如说生产线上,机器能够提高生产效率。由于机器比人快,一台自动检测机器能够承担好几个人的任务。而且机器不需要停顿、不会生病、能够连续工作,所以能够极大的提高生产效率。人眼检测还有一个致命的缺陷,就是情绪带来的主观性,检测结果会随工人心情的好坏产生变化,而机器没有喜怒哀乐,检测的结果自然非常可观可靠。
Speed and cost, machines are able to detect products faster. Especially when detecting high-speed moving objects, such as on the production line, the machine can improve production efficiency. Because the machine is faster than the person, an automatic detection machine can take on the task of several people. And the machine does not need to pause, will not be sick, can work continuously, so can greatly improve production efficiency. Human eye detection also has a fatal flaw, that is, the subjectivity of emotion, the test results will change with the mood of the workers, and the machine has no joys and sorrows, the results of the test is naturally very considerable and reliable.

由于机器视觉检测系统可以快速获取大量信息,而且易于自动处理,也易于同设计信息以及加工控制信息集成,因此,在现代自动化生产过程中,人们将机器视觉检测系统广泛地用于工况监视、成品检验和质量控制等领域。机器视觉检测系统的特点是提高生产的柔性和自动化程度。
Because the machine vision detection system can quickly obtain a large amount of information, and easy to process automatically, but also easy to integrate with the design information and processing control information, therefore, in the modern automated production process, people will be widely used in the machine vision detection system in the field of working conditions monitoring, finished product inspection and quality control and other fields. Machine Vision inspection system is characterized by improving the flexibility and automation of production.

在一些不适合于人工作业的危险工作环境或人工视觉难以满足要求的场合,常用机器视觉检测来替代人工视觉;同时在大批量工业生产过程中,用人工视觉检查产品质量效率低且精度不高,用机器视觉检测方法可以大大提高生产效率和生产的自动化程度。而且易于实现信息集成,是实现计算机集成制造的基础技术。
In some hazardous working environment which is not suitable for manual operation or where artificial vision is difficult to meet the requirements, machine vision detection is often used to replace artificial vision, and in the process of high-volume industrial production, the product quality efficiency is low and the accuracy is not high, The use of machine vision detection method can greatly improve the production efficiency and the degree of automation of production. And easy to realize information integration is the basic technology to realize computer integrated manufacturing.
