The core tip of this article : This article mainly explains the basic introduction of machine vision and the best choice for industry applications-high-precision machine vision dimensional measurement.
Machine vision, in simple terms, can be understood as adding a visual device to the machine, or a machine equipped with a visual device. The purpose of adding a visual device to the machine is to make the machine have visual functions similar to humans, thereby improving the degree of automation and intelligence of the machine.
Because machine vision systems can quickly obtain a large amount of information, and are easy to process automatically, and easy to integrate with design information and control information, therefore, in the current automated production process, machine vision systems are widely used in finished product inspection, quality control and other fields. The machine vision system can be used to detect defects, judge and select various products, and measure the size of objects.
The machine vision system has a measurement function, which can automatically measure the appearance size of the product, such as the measurement of the outline, aperture, height, area and other dimensions. In the production process of products, dimensional measurement is an indispensable step, and machine vision has better technical advantages than other measurement methods in dimensional measurement.
In the production process of products, dimensional measurement is an indispensable step, and machine vision has better technical advantages than other measurement methods in dimensional measurement. The non-contact measurement method of machine vision can avoid damage to the measured object and is suitable for situations where the measured object is not in contact, such as high temperature, high pressure, fluid, environmental hazards, etc .; at the same time, the machine vision system can simultaneously measure multiple sizes The measurement realizes the high efficiency of the measurement work and is suitable for online measurement. The measurement of tiny size is the strength of the machine vision system. It can use a high-power lens to magnify the object to be measured, so that the measurement accuracy reaches more than microns.
At the same time, the dimension measurement method based on machine vision technology has the advantages of low cost, high precision, and easy installation. In the automated manufacturing industry, machine vision is used to measure various dimensional parameters of the workpiece, such as length measurement, circle measurement, angle measurement, arc measurement, and area measurement. It is necessary to detect the basic geometric characteristics of the relevant area of ​​the workpiece. Not only can the size parameters of online products be obtained, but also online real-time judgment and sorting can be made for the products, and the application is very common. Coupled with powerful visual software, it is easy to adjust, flexible and convenient, and the measurement data can be stored to facilitate the establishment of statistical analysis, to quickly find problems and solve problems, which is the best choice for industry measurement technology.
