Machine vision system application becomes the leading trend in the inspection industry

In daily work, we will be exposed to many aspects of measurement problems, such as bottle cap detection, product surface defect detection, etc. In the production line, relying on people to make such measurements and judgments will be due to fatigue, personal differences, etc. Errors and errors are generated, but the machine goes on tirelessly and steadily. This had to introduce the concept of a machine vision system, a so-called machine vision systems, refers to the human eye in place of using a machine to make a variety of measurements and a system for the determination.

Machine vision systems generally include a light source, an optical system, a CCD camera / CMOS camera, an image capture card , an image processing unit, machine vision image processing software (image processing unit), a monitor, a communication/input and output unit, and the like. For each application, we need to consider the speed of the system and the processing speed of the image, the use of color or black and white cameras, the size of the detection target, the detection of defects or the need for the field of view, how high the resolution needs, how much contrast needs to be And other factors. From a functional point of view, a typical machine vision system can be divided into: an image acquisition part, an image processing part, and a motion control part.

The machine vision system is a relatively complex system. Since most of the objects monitored by the system are moving objects, the matching and coordination between the system and the moving objects is particularly important, so the operating time and processing speed of each part of the system. The wine has strict requirements. At present, there are a lot of domestic production enterprises in this area. In the case of Shaanxi Weiwei Digital Image Technology Co. , Ltd. , there are several series of streaming media capture cards that they can produce , so that users can build and develop themselves conveniently and quickly. The machine vision system has a great user experience.

The machine vision system has the following advantages : 1. Non-contact measurement, which does not cause any damage to the observer and the observer, thereby improving the reliability of the system; 2. Having a wide spectral response range, for example, invisible to the human eye. Infrared measurement expands the visual range of the human eye; 3. Long-term stable work, it is difficult for humans to observe the same object for a long time, while machine vision can perform measurement, analysis and recognition tasks for a long time.

At present, the application of machine vision is more and more extensive, and it is involved in the fields of industry, agriculture, national defense, transportation, medical care, etc. It can be said that the machine vision system has already formed part of our daily work life.
