Research on the Recognition and Location of Screw Cap on Steel Drum Cover Based on Machine Vision

In order to realize the robot automatic screw cap system, the recognition and location method of screw cap on steel drum cover based on machine vision is researched in this paper. Machine Vision System was established to acquire images from the screw cap and locate the workpiece based on coordinates of the screw cap center after digital image preprocessing. The corner detection algorithm based on Harris operator was used to obtain the rotating angle of screw cap with a stable key point. The experiment and simulation results showed that the method proposed in this paper has a good performance. This method can effectively improve the automation and flexibility of the steel drum production line.
