Machine vision is a technology that uses machines to replace the human eye for measurement and judgment, mainly through the image processing system to analyze the shape, color and other information of the target object, and then control the operation of the device

Core features:
The machine vision system converts the target into an image signal through an image acquisition device (such as CMOS/CCD camera), extracts the features (such as size, shape, color) after digitization, and finally controls the device action according to the discriminant results

Scope of application:
It covers industrial testing (such as defect detection, dimensional measurement), agriculture (such as crop monitoring), medicine (such as drug packaging inspection), military and aerospace, etc

System composition
Typical systems include optical systems (light sources, lenses, cameras), image acquisition modules, processing modules (filtering, edge detection and other algorithms) and control modules
