A Filter Capsule Detection and Correction Method Based on Visual Detection and PID Control Linkage

With the rapid development of the domestic filter capsule cigarette market, the quality control of filter capsule filter rods has become critical. Current production is mainly faced with problems such as filter capsule deflection, and traditional detection and adjustment methods have the challenges of low accuracy and untimely response. For this reason, this study proposes a method for correcting filter capsule deflection detection based on the interaction of visual detection and PID regulation linkage. First, an improved SIFT image stitching algorithm is used to improve the accuracy of visual localization. Then, the PID control algorithm is introduced to adjust the flywheel speed in real time to realize high-speed deflection correction. Finally, experiments have verified that this method can effectively improve the qualification rate of filter capsule filter rods, reduce production costs, and be of great significance to the quality control of filter capsule cigarettes in the tobacco industry.
