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 world's 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，机器视觉系统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。
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.
