Machine vision systems machine vision system is to improve the flexibility and degree of automation of the production. In some features not improve the flexibility and the degree of automation of the production.
Some visual system works thumbs visual system works diagram suitable for hazardous work environment or artificial vision suitable for manual operation is difficult to meet the requirements of the occasion, hazardous work environment or artificial vision of the common working industry is difficult to meet the requirements occasions, commonly used in machine vision machine vision instead of artificial vision; instead of artificial vision in large quantities at the same time; artificial visual inspection of product quality efficiency and accuracy is not high, in high-volume industrial production process of industrial production, machine vision inspection can greatly improve production efficiency and the degree of automation. Process, with artificial visual inspection of product quality efficiency and accuracy is not high, machine vision detection method can greatly improve the production efficiency and automation. And Machine Vision Machine Vision is easy to implement and easy to implement information integration information integration is achieved, is the basis of computer integrated manufacturing computer integrated manufacturing technology.
High precision machine vision system, you can quickly get a lot of information and automatic processing, this technology is widely used in the field of industrial inspection. Traditional labor-intensive detection mode, the machine vision system can replace a large number of detection workers, upgrade the simple tools of the human eye detection mode for high accuracy and fast automatic detection results. It is because of machine vision systems can quickly get a lot of information, but also easy to automatically process and information integration, modern automated production process, machine vision systems are widely used in assembly positioning, product quality testing, product identification, product size measurement.
Robot visual servo system is the organic integration of machine vision and robot control is a nonlinear, strong coupling of complex systems, covering image processing, robot kinematics and dynamics, control theory and other research areas.
The machine vision system means through machine vision products will be converted into an image signal pickup target, transfer to a dedicated image processing system, according to the distribution of pixels and brightness, color and other information into a digitized signal; image system for various operations on these signals to extract target features, and thus to control the action of equipment depending on the identified results.
The use of machine vision systems have the following five main reasons:
Accuracy - because the human eye physical constraints on the accuracy of the machine has obvious advantages. Even if the human eye depends on the magnifying glass or a microscope to detect the products, the machine will still be more precise, because of its precision can be achieved thousandth of an inch.
Reproducibility - machine testing work can be completed in the same way again and again and not feel tired. In contrast, the human eye each detection products will be slightly different, even if the product is identical.
Speed - the machine faster detection products. Especially when high-speed moving objects detected, for example, the production line, the machine can be improved production efficiency.
Objectivity - the human eye to detect there is a fatal flaw, is the emotional subjectivity, the test results will be good or bad with the workers' mood changes, and the machine does not have emotions, naturally very impressive and reliable test results.
Cost - the machine faster than a human, an automatic inspection machine able to assume the tasks of several people. And the machine does not need to pause, do not get sick, be able to work continuously, it can greatly improve production efficiency.
Machine vision system can quickly obtain a large amount of information, and easy, but also easy with the design information and process control information integration, modern automated production process, machine vision systems are widely used in working condition monitoring, product testing and quality control and other fields. The machine vision system is to improve the flexibility and degree of automation of the production. Difficult to meet the requirements of the occasion in a dangerous work environment is not suitable for manual operation or artificial vision, commonly used in machine vision to replace artificial vision; doing so visually check the efficiency of product quality at the same time in large volume industrial production process with low accuracy is not high. machine vision detection method can greatly improve production efficiency and the degree of automation. And machine vision easy to implement information integration is the basis of computer integrated manufacturing technology.
