Colour vision for industrial applications
暂无分享,去创建一个
A vision system for colour object recognition is presented. The proposed system is low in cost and sufficiently fast and reliable for simple industrial applications. The system comprises a fiber optic illumination system lenses, a camera, a frame grabber and an IBM PC/AT microcomputer with a colour monitor. DT 2853/2873 frame grabbers are used for digitizing the image. The recognition algorithms are based on red-green-blue and hue-saturation-intensity modes. The approach and development of these algorithms are elaborated. The accuracy, reliability and speed of recognition has been very good. The recognition is based on closest path, thresholding and mathematical modeling algorithms.<<ETX>>
