Abstract

Background: Aiming at the characteristics of PCB photoelectric image which have ambiguity and noise, a circle detection method of PCB photoelectric image based on improved Hough transform is proposed. Methods: Firstly, the basic principle of circle detection based on traditional Hough transform algorithm is discussed, and its disadvantages are pointed out. Secondly, the basic principle of circle detection method based on improved Hough transform is analyzed in detail, and it has some advantages such as smaller amount of data and faster speed. Results: Lastly, in order to prove the correctness of the basic principle analysis, a real experiment of PCB photoelectric image circle detection is actualized, both the subjective results and the objective results verify the superiority of the method. Conclusion: By using the method, the edge information obtained is the best and the computed time is the shortest in these methods mentioned in the experiment.
