Abstract
In order to eliminate user's interaction, a new method based on concentric circles pattern is proposed to calibrate a camera automatically and accurately. Firstly, the imaged centers of concentric circles are located using the principles of cross-ratio and pole-polar; secondly, different centers are identified by cross-ratio; finally, the topology of imaged centers is established to calibrate the camera automatically. The effectiveness and accuracy of the method is demonstrated by experiments with simulated and real images. It is shown that this method has high robustness and precision, can be efficiently used in many applications.
