Intelligence is a black hole
In the future, it is bound that many labor industries will be transformed
Intelligent machine vision meets industrial automation
What kind of sparks will be produced......
What is machine vision?
In short, machine vision is to use machines instead of human eyes to measure and judge.
What is industrial automation?
Industrial automation refers to the realization of information processing and process control of measurement, manipulation, etc. according to the expected goal without direct manual intervention.
Application of machine vision in industrial automation inspection
1. Guidance and positioning: vision positioning requires that the machine vision system can quickly and accurately find the part to be measured and confirm its position. The machine vision is used to locate the loading and unloading materials to guide the manipulator to grasp accurately. In the field of semiconductor packaging, the device needs to adjust the pickup head according to the chip position information obtained by machine vision, accurately pick up the chip and bind it. This is the most basic application of visual positioning in the field of machine vision industry.
2. Appearance inspection: to detect the quality problems of products on the production line, which is also the link that takes the most place of labor. For example, machine vision is involved in the field of medicine, its main detection includes size detection, bottle body appearance defect detection, bottle shoulder defect detection, bottle mouth detection and so on.
3. High precision detection: the precision of some products is high, reaching 0.01 ~ 0.02 M or even u level, which cannot be detected by human eyes and must be completed by machine.
4. Recognition: it is to use machine vision to process, analyze and understand the image, so as to identify various targets and objects with different patterns. It can be used in auto parts, food, medicine and so on.
Image scanning recognition in machine vision technology
In industrial automation detection, image scanning recognition generally includes spray code recognition, bar code recognition, two-dimensional code recognition, and character recognition.
What are the difficulties of barcode scanning and recognition?
Noise, mirror, reflection, uneven exposure, perspective, quiet area disturbance, cavity, damage
How to solve it?
There is a customized algorithm to solve the problem of noise area disturbance and code damage, and increase the reading rate with the help of various light sources.
What is the difficulty of spray code scanning recognition?
Different stroke width, dot matrix text, fixed text contact, low contrast, background noise, uneven local lighting
How to solve it?
Spray code detection is more difficult than bar code detection, through camera preprocessing and image correction, accurate segmentation algorithm, combined with text training and range limitation, at the same time, with the help of various light sources to increase the reading rate.
Machine vision detection system really makes industrial matters automatic. When industrial robots have the ability of visual inspection, they can judge things better, so that they can solve some problems intelligently and flexibly.
