Abstract

During the optical fiber winding, larger or smaller lag angle would lead to superposition or spacing winding which would seriously influence the quality and stability of optical fiber bobbin. So the precise measurement and control of the lag angle was a key technique in optical fiber precise winding. Based on computer digital image technology, a new measurement scheme was proposed. According to the measurement requests, hardware of the image collection system and the image processing system were designed. By means of the image collection system and the designed program, the lag angle image was successfully collected. The resolution and efficiency of the Hough transform and the concentric cirque seeking method for image recognition were tested. The results showed that the efficiency of the Hough transform and the concentric cirque seeking method is low. So an improved Hough transform method was developed and the efficiency was numerically tested. The results showed that the improved Hough transform method was much more efficient and 0.1° measurement error of the lag angle can be achieved.
