1. At present, machine vision is developing in two general directions:
1. Applications in embedded
In the past ten years, embedded products such as sensors and smart cameras have gradually occupied part of the machine vision market. Smart camera is a highly integrated micro-mini machine vision system, which integrates image acquisition, processing and communication functions into a single camera, thus providing a machine vision solution with multiple functions, modularity, high reliability, and easy implementation Program.
The future development direction is that the performance gap between smart cameras and microcomputer-based machine vision systems is getting smaller and smaller, and smart cameras will be more and more widely used due to their low cost, ease of use, compact structure and other advantages. Therefore, more and more camera and board manufacturers are developing smart cameras.
2. Application of PC-based machine vision
The PC-based vision system takes advantage of the PC’s openness, high programming flexibility and good Windows interface, while the overall system cost is low. PC-Based systems usually contain high-performance image acquisition cards, or high-speed interfaces, which can generally connect multiple cameras and provide library function support for multiple development platforms (VC, VB, LabVIEW, etc.). The application program interface under Windows is beautiful and accepted by the majority of users. With the development of computer hardware technology, the ability to process image data is becoming stronger, which is very conducive to the development of machine vision.​
​
2. Development trend of AOI automatic optical detector
1. The development trend of machine vision in technology is digitization, real-time, and intelligence.
The digitization of image acquisition and transmission is an inevitable trend in the technical development of AOI automatic optical detectors. More digital cameras, wider image data transmission bandwidth, higher image processing speed, and the introduction of more advanced image processing algorithms will be more widely used.
2. Prices continue to fall and market share is rapidly expanding
With the advancement of technology and fierce market competition, as well as the localization of many products, price drops have become an inevitable trend, which means that AOI automatic optical inspection technology will gradually be accepted. In addition, the market for AOI automatic optical detectors will continue to grow. On the one hand, the application fields of machine vision products have been adopted, and the dependence on machine vision products will be stronger; on the other hand, machine vision products will be applied to other broader fields.
3. The industry is developing faster
The increase in professional companies in the machine vision industry, the increase in investment and employees, and the intensified competition is the development trend of the machine vision industry in the next few years. As an emerging industry, the machine vision industry will gradually develop and mature and will receive more and more attention. Competition in the development of the industry will inevitably bring new opportunities and development, but at the same time it will be accompanied by more opportunities.
According to the detection function, it can be divided into: positioning, defect detection, counting/missing detection, and size measurement.
According to the carrier installed, it can be divided into: online detection system and offline detection system.
According to the detection technology, there are usually stereo vision detection technology, spot detection technology, size measurement technology, OCR technology, etc.
Machine vision inspection is essential to eliminate product defects such as blemishes, blurs, chips or dents to ensure product functionality and performance. Therefore, it has been widely used in product defect detection and size detection in various major industries. For example, the vision system can be used to detect multiple items of products, the vision system can be used to detect defects or offset stitches of electronic components, and the vision system can be used to measure the shape of syringe parts or distinguish colors to check incorrect assembly.
At the same time, license plate recognition and flow inspection in the transportation industry, packaging inspection in the pharmaceutical industry, capacity inspection and outer packaging inspection in the beverage industry, cigarette label inspection and outer packaging inspection in the tobacco industry, assembly inspection in the automobile industry, and printing quality in the printing industry Detection, fabric defect detection in the textile industry, screw detection in the hardware industry, cargo sorting in the transportation industry, fruit sorting in the food industry, welding detection and assembly positioning in the electronics industry, steel plate surface defect detection in the steel industry, smart meter reading, Smart meter reading, etc. have applications.
Based on the visual inspection technology of AOI automatic optical detector image processing technology, the automatic inspection of the entire product plays a very important role in controlling product quality and ensuring product quality. It can prevent the outflow of unqualified products and improve the core competitiveness of the enterprise. The company has not only obtained social benefits, but its AOI automatic optical inspection equipment has brought substantial economic benefits to the company.
Vision robot automation technology means to ensure the high efficiency and high quality of product processing, reduce the intervention of human factors in the production process, and then improve the working environment and strengthen environmental protection, and improve energy efficiency. In the field of intelligent special equipment, it is necessary to focus on the development of a new generation of large-scale power and grid equipment, machine vision technology, robotics industry, full-section roadheaders, fast-integrated flexible construction equipment and other intelligent large-scale construction machinery, as well as large-scale advanced and efficient intelligent agricultural machinery, etc. .
