A Combined Method for Concentric Circles Detection in Image of O-Shape Rubber Ring

Article Preview

Abstract:

Traditional Hough transform (HT) methods based on parameters decomposition do not give good result for concentric circle detection, for the reasons of its large amount of calculations, high demand of storage space and low efficiency in real-time application. To compensate the weaknesses, this paper employs a kind of improved Hough transform method which aims at reducing the parameters space. In this paper, the detection method is further improved through adding an edge detection procedure based on global threshold. The experimental results show that this algorithm meets the on-line detection of high accuracy requirement, with superior real-time performance and stronger anti-interference ability.
