The original image collected by CCD vision imaging system often has a lot of noise and distortion, this kind of data can not be directly used in machine vision detection system. In order to eliminate the interference of the external environment to the image acquisition, it is necessary to preprocess the image, such as image analysis and recognition.
Machine vision system equipment can detect a lot of products, almost you can think of the basic industry can be used to detect CCD machine vision system. For example: the detection of screws and nuts, the detection of precision hardware parts, rubber ring O ring, plastic parts, capacitance and inductance, magnetic core detection, powder metallurgy, electronic products, auto parts, mobile phone parts and so on, many human eye detection positions can almost be replaced.
Machine vision system refers to the machine vision equipment, namely the image uptake device (CCD, CMOS), will be shot into the target into image information, and then transmitted to a special image processing system, according to the distribution of pixels, brightness and color information, into digital signals, image system in these signals for various operations to extract the characteristics of the target, Then according to the results of the judgment to control the field equipment to carry out a series of operations.
