Roundness Measurement in Spring Clamps Based on a Novel Particle Swarm Optimization

Xia Zhu and Renwen Chen

Abstract—One important inspection step in spring clamp is the determination of roundness value. Detect the circle from digital images is very important in computer vision. In view of clamp and the geometrical characteristics of the circular, a new optimization algorithm was proposed to extract image circle. Circle extraction is equivalent to the points search and extraction in the circle. Point search strategy is an optimization problem. Particle swarm optimization (PSO) is an effective global optimization method. Self-tuning parameters were achieved by using the improved particle swarm algorithm along with the geometric properties of the round, and detected effective point of band image so as to realize the recognition and detection of the circle. A large number of tests show that the proposed algorithm has good robustness and precision compared with the existing PSO algorithms. The main advantages of this method as compared with other methods include the considerable lower cost of facilities, easier maintenance and getting more accurate.
