工业自动化为什么需要机器视觉检测技术

所谓机器视觉,就是用机器代替人眼来做测量和判断。是指通过机器视觉检测设备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,那么工业自动化为什么需要机器视觉检测技术呢?主要表现如下几个地方。
The so-called machine vision is to use the machine instead of the human eye to do measurement and judgment. Refers to the machine vision detection equipment will be ingested target into image signals, transmitted to a dedicated image processing system, according to the pixel distribution and brightness, color and other information, into digital signals; So why does industrial automation require machine vision detection technology? The main performance is as follows.

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 physical limitations of the human eye, the machine has obvious advantages in terms of 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 be accurate up to one thousandth of an inch. Machines can do the tests one at a time in the same way without feeling tired. In contrast, the human eye has a slight difference every time it detects a product, even if it is identical.

速度和成本,机器视觉检测设备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。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。成本这块,由于机器比人快,一台自动视觉检测设备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。
Speed and cost, machine vision inspection equipment can detect products more quickly, especially when detecting objects moving at high speeds, such as on production lines, the machine can increase productivity。 Human eye detection also has a fatal defect, is the subjectivity of emotions, test results will be with the worker's mood change, and the machine is not happy and sad, the results of the test is naturally very reliable。 Cost this, because the machine is faster than the human, an automatic visual inspection equipment machine can take on several people's tasks, and the machine does not need to stop, will not be sick, can work continuously, so can greatly improve productivity。

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,机器视觉系统的特点是提高生产的柔性和自动化程度。
Because machine vision inspection systems can quickly obtain large amounts of information, are easy to handle automatically, and are easy to integrate with design information and processing control information, machine vision systems are widely used in modern automated production processes in the fields of condition monitoring, finished product inspection and quality control.
Machine vision systems are characterized by increased flexibility and automation in production.
