First, the characteristics of machine vision:
1, high-precision: the size of the error detection is less than 0.1mm.
2, continuity: a long time in a row, there is no human visual fatigue.
3, high-efficiency: to replace a large number of conventional sensors and artificial means of detection.
4, flexibility: can adapt to the variety of detection there is no need to replace hardware, software, you can simply switch appropriate.
5, high reliability: non-contact measurement, noninvasive detection and improved reliability of the system.
6, to adapt to a wide range: a wide range of spectral response can be observed not be able to see the human world, to expand the scope of human vision.

Machine vision systems pose:
By the light / optical / camera / computer / image capture card / image processing software / image analysis applications such as constituted.
Third, machine vision of the workflow:
Image Acquisition → → image processing properties → Extracting Discriminant analysis of the export control →
Fourth, detection of machine vision products, the scope of application:
Detection of size, location detection, shape detection, identification detection, color detection, light detection, optical-testing, state testing
