Machine vision or computer vision is an important aspect of pattern recognition research, which is the use of robots instead of the human eye for measurement and judgment. Computer vision is usually divided into low-level vision and high-level vision two categories, low-level vision mainly performs pre-processing functions, such as edge detection, mobile target detection, texture analysis, as well as stereoscopic shape, surface color, etc. , the main purpose is to make the object sseen more prominent. This is not the stage of understanding. High-level vision is mainly to understand objects, need to master the knowledge related to objects.top machine vision inspeciton system manufacturer.

The cutting-edge topics of machine vision include: parallel processing of real-time images, compression, transmission and recovery of real-time images, modeling and recognition of 3D scenery, dynamic and tempo vision, etc.

Machine vision system refers to the image ingested target through the image ingestion device into the image signal, transmitted to a dedicated image processing system, according to the pixel distribution and width, color and so on, into a digital signal, the image system to these signals for various operations, extract the characteristics of the target, Then according to the results of the discrimination to control the scene of the equipment action. The main goal of machine vision is to enable the computer to recognize three-dimensional bad environment information through two-dimensional images, and to perceive and process geometric information such as shape, position, attitude and motion of objects in three-dimensional environment.

There is a great deal of intersection between machine vision and pattern recognition, the main difference between the two is that machine vision pays more attention to the processing of three-dimensional visual information, and pattern recognition only cares about the categories of patterns. In addition, pattern recognition also includes non-visual information such as hearing.

In foreign countries, the application of machine vision is quite popular, mainly concentrated in electronics, automotive, metallurgy, food and beverage, spare parts assembly and manufacturing industries. Machine vision systems have been widely used in all aspects of quality inspection. In the machine vision products just started, currently mainly concentrated in the pharmaceutical, printing, packaging, food and beverage industries, but with the rapid development of domestic manufacturing industry, the most demand for product testing and quality continue to improve, all walks of life on image and machine vision technology industry automatic demand will be greater and larger, Therefore, machine vision in the future manufacturing industry will have a lot of room for development.
