Abstract :
A method was proposed to inspect the seasoning packets of instant noodles on-line after analysis the image of instant noodles. The vision system was built up to capture the image of noodle cake with seasoning packets. Noodle cake was located and salt packets were recognized by method of histogram statistics of brightness in HIS color model, threshold and contour detection. Vegetable and oil packets were inspected by the histogram statistics of Hue. Testing on actual production line, the system has the identification rate of 100%, missed rate of 0, false detection rate of 99%, and the detection speed of better than 20 per minute.
