At present, the intelligentization is completely used in integrated chip manufacturing workshops such as mobile phones, computers and the like, wherein a vision system is widely applied, the vision system generally consists of an illumination system, an OCD (optical clear) camera or lens, an image acquisition card, an industrial computer and a control mechanism, and the machine vision system is used for replacing human eyes with a machine to carry out various measurements and judgments. The system is an important branch of computer science, integrates the technologies of optics, mechanics, electronics, computer software and hardware and the like, and relates to a plurality of fields of computers, image processing, mode recognition, artificial intelligence, signal processing, optical-mechanical-electrical integration and the like. The rapid development of image processing, pattern recognition and other technologies also greatly promotes the development of machine vision.

A typical industrial machine vision system includes: a light source, a lens (a fixed focus lens, a zoom lens, a telecentric lens, a microscope lens), a camera (including a CCD camera and a COMS camera), an image processing unit (or an image capturing card), image processing software, a monitor, a communication/input/output unit, and the like.

The machine vision detection system adopts a CCD camera to convert a detected target into an image signal, transmits the image signal to a special image processing system, converts the image signal into a digital signal according to information such as pixel distribution, brightness, color and the like, performs various operations on the signal by the image processing system to extract characteristics of the target, such as area, quantity, position and length, and outputs results according to preset allowance and other conditions, such as size, angle, number, qualification/disqualification, existence/nonexistence and the like, thereby realizing the automatic identification function.

Machine vision systems are characterized by increased production flexibility and automation. In some dangerous working environments which are not suitable for manual operation or occasions which are difficult for manual vision to meet the requirements, machine vision is commonly used to replace the manual vision; meanwhile, in the process of mass industrial production, the efficiency of checking the product quality by using manual vision is low, the precision is not high, and the production efficiency and the automation degree of production can be greatly improved by using a machine vision detection method. And the machine vision is easy to realize information integration, and is a basic technology for realizing computer integrated manufacturing. The product can be measured, guided, detected and identified on the fastest production line, and the production task can be finished with guaranteed quality and quantity. Therefore, in modern automated production processes, machine vision systems are widely used in the fields of condition monitoring, finished product inspection, and quality control.

In the industrial application, the machine vision technology is used for replacing manpower in the industries of pharmacy, packaging, electronics, automobile manufacturing, semiconductors, textiles, tobacco, transportation, logistics and the like, and the production efficiency and the product quality can be improved. For example, in the logistics industry, the machine vision technology can be used for sorting and classifying the express, manual sorting of most express companies can be avoided, the damage rate of articles is reduced, the sorting efficiency can be improved, and the manual labor is reduced.

Illumination: is an important factor influencing the input of a machine vision system, and directly influences the quality and application effect of input data. Since there is no general machine vision lighting, the corresponding lighting device is selected for each specific application instance to achieve the best results. The light source can be divided into visible light and invisible light. Several visible light sources commonly used are white lamps, fluorescent lamps, mercury lamps and sodium lamps. The visible light has the disadvantage that the light energy does not remain stable. How to keep the light energy stable to a certain extent is a problem which needs to be solved urgently in the practical process. On the other hand, the ambient light may affect the image quality, so the shielding method can be used to reduce the effect of the ambient light. The lighting system can be divided into: back lighting, forward lighting, structured light, and stroboscopic lighting, among others. Among them, the back lighting is that the measured object is placed between the light source and the camera, which has the advantage of obtaining high contrast images. The forward illumination is such that the light source and the camera are located on the same side of the object to be measured, in a manner that facilitates installation. The structured light illumination is to project a grating or a line light source and the like onto a measured object, and demodulate three-dimensional information of the measured object according to distortion generated by the grating or the line light source and the like. The stroboscopic illumination is to irradiate high-frequency light pulses on an object, and the shooting of a camera is required to be synchronous with a light source.

Lens FOV (field Of Vision) = required resolution subpixel Camera size/PRTM (part measurement tolerance ratio) lens selection Note ① focal length ② target height ③ image height ④ magnification ⑤ image to target distance ⑥ center point/node ⑦ distortion

A camera: according to different standards, the method can be divided into the following steps: standard resolution digital cameras and analog cameras, etc. Different cameras and high-resolution cameras are selected according to different practical application occasions: line scanning CCD and planar array CCD; monochrome cameras and color cameras.

An image acquisition card: the image acquisition card is only a component of the complete machine vision system, but it plays a very important role. The image acquisition card directly determines the interface of the camera: black and white, color, analog, digital, and the like.

Typically a PCI or AGP compatible capture card, can quickly transfer images to computer memory for processing. Some acquisition cards have a built-in multi-way switch. For example, 8 different video cameras may be connected and then tell the acquisition card to capture the information with that one camera. Some acquisition cards have built-in digital inputs to trigger the acquisition card to capture, and the digital output port triggers the gate when the acquisition card captures an image.

A visual processor: the vision processor integrates the acquisition card and the processor. In the past, when the computer speed was slow, the vision processor was adopted to accelerate the vision processing task. At present, the acquisition card can quickly transmit images to the memory, and the computer is much faster, so that the vision processor is less at present.

In the above embodiments, the best mode of the present invention has been described, it is obvious that many changes can be made under the inventive concept, and here, it should be explained that any changes made under the inventive concept will fall into the protective scope of the present invention.
