Abstract :
Concentric circles are often used as calibration features since they possess good geometric properties. This paper presents an efficient method for the detection of projected concentric circles in the image plane while considering their special geometric properties. The proposed method is capable of detecting partially visible concentric circles. Experimental results demonstrate the validity of the proposed approach.
