Abstract

The system that can recognize whether a pinhead is inaccurate fitting and location in hackle is introduced. The system includes several parts: lamp-house, pick-up camera, movement control card, step motor, hackle and switch. Image collected by pick-up camera is auto-threshold, binary, located and template matched. As there is a tilt between hackle and pins, collected image must be rectified before matching template. After the comparison of template and searching graph, the system can get similarity automatically, the inaccurate fitting pinhead can be recognized easily, and it also can give an alarm while there is inaccurate fitting. It is proved that recognizable ability and accuracy can meet the demand of the production completely by experiment.
