机器视觉检测基础知识介绍

现如今,中国已经成为世界机器视觉发展最为活跃地区,应用范围涵盖了工业、农业、医药、军事、航天、气象等国民经济各个行业。虽然机器视觉的成长速度非常快,但是还是有很多人对机器视觉并不了解,今天我们来聊一聊机器视觉检测的基础知识。

Today, China has become the worlds most active machine vision development, the application of industry, agriculture, medicine, military, aerospace, meteorology and other national economy industries. Although machine vision is growing very fast, there are still a lot of people who do not understand machine vision, today we talk about the basics of machine vision detection.

机器视觉就是用机器代替人眼来做测量和判断,机器视觉是指通过机器视觉产品,即图像摄取装置,分CMOS和CCD两种,将被摄取目标转换成图像信号,传送给专用的图像处理,根据像素分布和亮度、颜色等信息,转变成数字化信号;图像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。

Machine vision is to use machine instead of the human eye to do measurement and judgment, machine vision system refers to through the machine vision products, that is, image ingestion device, sub-CMOS and CCD two kinds, will be ingested target into image signal, transmitted to a dedicated image processing system, according to pixel distribution and brightness, color and other information, into digital signal The image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action in the field according to the result of the discrimination.

机器视觉具有高效率、高度自动化的特点,可以实现很高的分辨率精度和速度。机器视觉与被检测对象无接触,安全可靠。机器视觉检测是采用CCD照相机将被检测的目标转换成图像信号,传送给专用的图像处理,根据像素分布和亮度、颜色等信息,转变成数字化信号。

Machine vision system has high efficiency and high automation, which can achieve high resolution accuracy and speed. The machine vision system has no contact with the detected object and is safe and reliable. Machine vision detection system is the use of CCD camera will be detected target into image signal, transmitted to a dedicated image processing system, according to pixel distribution and brightness, color and other information, into a digital signal.

图像处理对这些信号进行各种运算来收取目标的特征,如面积、数量、位置、长度,再根据预设的允许度和其他条件输出结果,包括尺寸、角度、个数、合格/不合格、有/无等,实现自动识别功能。

The image processing system performs various operations on these signals to collect the characteristics of the target, such as area, quantity, position, length, and then outputs the results according to the preset tolerance and other conditions, including size, angle, number, conformity/nonconformity, have/not, etc., to achieve automatic identification function.

视觉

视觉是一个生理学词汇。光作用于视觉器官,使其感受细胞兴奋,其信息经视觉神经系统加工后便产生视觉(vision)。通过视觉,人和动物感知外界物体的大小、明暗、颜色、动静,获得对机体生存具有重要意义的各种信息,至少有80%以上的外界信息经视觉获得,视觉是人和动物最重要的感觉。
