摘要: In present market, there is no automatic detected device for register in medium and small single-sheet offset, and the registration precision usually adjusted by handwork that is time-consuming and imprecision. To solve this problem, an automatic detected device for register of single-sheet offset based on image processing is proposed. The device takes photos of registration markers through high precision CMOS camera controlled by single chip computer, and then detects transversal deviation, longitudinal deviation, and diagonal deviation of registration markers through Hough transform. Experiments indicate that transversal deviation precision and longitudinal deviation precision of this device is 0.01 millimeter, when this automatic detected device is applied.
