In practical application, different cameras 5 can be selected according to different practical application occasions, such as a line scanning CCD, an area array CCD, a monochrome camera 5 and a color camera 5. According to the application requirement, the camera 5 can output standard monochromatic video (RS-170/CCIR), composite signal (Y/C), RGB signal, and also can output non-standard progressive scanning signal, line scanning signal, high resolution signal, etc.; when selecting the lens of the camera 5, attention should be paid to: focal length, target height, image height, magnification, image-to-target distance, distortion, etc.
The number of the detection mechanisms can be 1, or a plurality of detection mechanisms, and if the number of the detection mechanisms is a plurality of detection mechanisms, all the detection mechanisms are sequentially arranged above the conveyor belt 2 along the conveying direction of the conveyor belt 2, and the image data of the multi-path camera 5 can be acquired by switching through an image acquisition card, or the image data of the multi-path camera 5 can be acquired simultaneously through synchronous control.
When using an image capture card, it is usually necessary to install the image capture card in a host computer in the form of a plug-in card, and the main task is to transmit the image data output by the camera 5 to the host computer, specifically, it can convert the analog signal or digital signal from the camera 5 into an image data stream with a certain format, and at the same time, can control some parameters of the camera 5, such as trigger signal, exposure/integration time, shutter speed, etc.
Generally, the image acquisition card may have different hardware structures and different bus forms for different types of cameras 5, such as PCI, PCI64, Compact PCI, PCIO4, ISA, etc., and the image acquisition card directly determines the interface of the camera 5: black, color, analog, digital, etc., more typically PCI or AGP compatible capture cards, can quickly transfer image data to a PC for processing.
It should also be noted that lighting is an important factor affecting machine vision system input, which directly affects the quality and application of the input data. Therefore, in order to further improve the imaging quality of the camera 5, the corresponding lighting device 6 may also be selected for each specific application instance to achieve the best results. The lighting devices 6 can be classified into visible light lighting and invisible light lighting according to the visibility of light, and several common visible light lighting devices 6 are incandescent lamps, fluorescent lamps, mercury lamps and sodium lamps.
In other embodiments, the illumination device 6 can also be selected from back illumination, structured light, stroboscopic illumination, etc. according to the illumination method, wherein the back illumination is that the object is placed between the light source and the camera 5, which has the advantage of obtaining high-contrast images; 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 a high-frequency light pulse on an object, so that instantaneous high-intensity illumination can be obtained, but the shooting of the camera 5 is required to be synchronous with the light source.

Specifically, the industrial personal computer 4 is equipped with machine vision software to process image data sent by the detector, and then obtains a result through certain operation, and the output result may be PASS/FAIL signal, coordinate position, character string, and the like. Common machine vision software comes in the form of C/C + + image libraries, Active X controls, graphical programming environments, etc., and may be either function-specific (such as for LCD inspection only, BGA inspection, template alignment, etc.) or general-purpose (including positioning, measurement, barcode/character recognition, blob inspection, etc.).
The industrial control computer 9 also comprises control devices, such as I/O, motion control units, level translation units, etc., which, once the vision software has completed the image analysis (unless it is used for monitoring only), need to communicate with external units to complete the control of the production process; some simple controls can directly utilize the I/O of a partial image acquisition card, and the relatively complex logic/motion control must rely on an additional programmable logic control unit/motion control card to realize necessary actions.
The working process of appearance detection based on the industrial personal computer 9 is as follows:
1. when the photoelectric switch 7 detects that the object to be detected moves to be close to the center of the visual field of the camera 5, a trigger signal is sent to the industrial personal computer 4;
2. the industrial personal computer 4 sends a stop signal to the conveyor belt driving motor 3 according to a trigger signal to control the conveyor belt 2 to stop moving, and the industrial personal computer 4 respectively sends trigger pulses to the camera 5 and the lighting device 6 according to a preset program and time delay;
3. the camera 5 opens an electronic shutter, and the exposure time can be set in advance;
4. the lighting device 6 is turned on and the on time of the light should match the exposure time of the camera 5;
5. after the camera 5 is exposed, formally starting scanning and outputting of a frame of image;
6. the image acquisition card receives an analog video signal, digitizes the analog video signal through A/D (analog/digital) or directly receives digital image data digitized by the camera 5 and stores the digital image data in the internal memory of the industrial personal computer 9;
7. the machine vision software of the industrial personal computer 9 processes, analyzes and identifies the image data to obtain a measurement result or a logic control value;
and the industrial personal computer 9 issues a control command to the industrial personal computer 4 according to the processing result so as to control the action of the conveyor belt 2, perform positioning, correct motion errors and the like.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
