Components of a Machine Vision System
The machine vision system provides light sources through professional lighting systems (such as 3D structured light, infrared lighting, line lasers); uses industrial cameras and other camera parts to convert the captured targets into image signals, and transmit them to a dedicated image processing system to obtain the image signal. The morphological information of the photographed target. According to the pixel distribution, brightness, color and other information, the imaging part converts it into a digital signal; the image system performs various operations on these signals to extract the characteristics of the target and generate point clouds and other information. The vision system can tell the detected content and transmit it to the relevant control system, so that the control system can control the equipment action on the spot according to the result of the judgment.
A typical industrial machine vision system includes: light source (3D structured light, line laser, various customized light sources), lens (fixed focus lens, zoom lens, telecentric lens, microscope lens), camera (including CCD camera and CMOS camera) ), image processing unit (or image capture card), image processing software, monitor, communication/input output unit, etc.
