24V 0.6W / 1.1W Machine Vision Ring Light Uniform Illumination For Parts Alignment

Working principle of machine vision system

Machine vision system can transfer the optical signal into image signal through image acquisition hardware, i.e. camera, shot, light source, etc., and transmit it to image processing software. Image processing software can extract the feature of target according to pixel luminance and color distribution, and make the corresponding judgment to realize the inspection by controlling the site equipment. Vision processing system comprises hardware and software. Machine vision camera can be further divided into intelligent camera and PC-based vision system according to the hardware. The core of PC-based machine vision system includes light source, shot, camera and vision processing system. The main function of the shot is to image the target onto the sensitive film of the camera. The main function of the camera is image acquisition, transferring the optical signal to electronic signal to import to the PC. The core technology of the software is image processing and algorithm analysis, which include image-enhance, image segmentation, feature extraction, image recognition and analysis. Through the image processing and analysis, the system can judge the product quality, measure the dimension, and display/execute the corresponding action according to the result signal.
