Application of machine vision inspection system

 The machine vision inspection system mainly uses a CCD camera to convert the detected target into an image signal, and transmits it to a dedicated image processing system. According to the pixel distribution, brightness, color and other information, it is converted into a digital signal. The image processing system performs various processing on these signals. A kind of operation is used to extract the characteristics of the target, such as area, quantity, position, length, and then output the results according to the preset tolerance and other conditions, including size, angle, number, qualified/unqualified, presence/absence, etc., to achieve Automatic recognition function. So what are the applications of machine vision inspection systems? The following is explained to you by the editor of Xinxiwang:

(1) It can be divided according to detection functions: positioning, defect detection, counting/missing detection, and dimensional measurement.

(2) According to the carrier installed, it can be divided into: online detection system and offline detection system.

(3) According to detection technology, there are usually stereo vision detection technology, spot detection technology, size measurement technology, OCR technology, etc.

Machine vision inspection is critical 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 dimensional inspection in various major industries. For example, the vision system can be used to detect various items of the product, the vision system can be used to detect defects or offset pins in electronic components, the vision system can be used to measure the shape of syringe parts or distinguish colors to check for incorrect assembly, etc.

At the same time, license plate recognition and flow detection in the transportation industry, packaging testing in the pharmaceutical industry, capacity testing and outer packaging testing in the beverage industry, cigarette label testing and outer packaging testing in the tobacco industry, assembly testing in the automotive industry, and printing quality in the printing industry Inspection, cloth 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, intelligent meter reading, Smart meter reading and so on have applications.
