Appearance inspection: introduction to the application field of machine vision solutions

Date:2021-10-15 17:29:03Views:1117

Machine vision is a branch of artificial intelligence, which uses machines instead of human eyes to measure and judge. Driven by the demand for industrial automation and intelligent manufacturing, the penetration of machine vision downstream applications has increased, and the industry space is broad. At present, the application of machine vision solution is extending from industrial field to non industrial field to realize the positioning, detection, measurement, recognition and judgment of things. Its main areas are:

外观检测:机器视觉解决方案应用领域介绍

1、 Part inspection

Part inspection is one of the most important applications of machine vision technology in industrial production. In the process of manufacturing, almost all products are faced with quality inspection. Machine vision technology is widely used in product inspection. The main applications of part inspection include:

1. Existence detection

The object of existence detection includes whether a part, a pattern or the whole object exists.

2. Surface defect detection

The object of surface defect detection is the elements on the two-dimensional plane, including holes, stains, scratches, cracks, bright spots, dark spots and other common surface defects. These defects, especially holes and cracks, may seriously affect the product quality and use safety. It is very important to accurately identify defective products.

2、 Dimension measurement

Machine vision measurement technology is a non-contact measurement method based on optical imaging, digital image processing and computer graphics. It has a strict theoretical basis and a wider measurement range. Compared with the traditional measurement method, it has higher measurement accuracy and efficiency, and can complete the online measurement of two-dimensional and three-dimensional dimensions of articles.

3、 Target recognition

Using the functions of image processing, analysis and understanding in machine vision technology, we can accurately identify a kind of preset target or object model. The main applications in the industrial field are bar code reading, QR code scanning and recognition, etc.

4、 Industrial manipulator based on 3D vision guidance

The traditional industrial manipulator completes the work of grasping, handling and assembly from a fixed position. These steps are fixed processes.

The industrial manipulator based on 3D vision guidance can identify the placement position and posture of the items to be grabbed, flexibly control the manipulator through data processing, and sort the materials in a disordered or semi disordered state.

The above is the related content of "appearance test" brought by the core creation test. I hope it can be helpful to you. We will bring more wonderful content in the later stage. As an important application of industrial Internet, the field of machine vision represents the future development trend of advanced productivity and science and technology, and its investment opportunities are paid more and more attention and explored by the market.
