Plane metric rectification from a single view of multiple coplanar circles

Metric rectification has important applications to topics such as single-view metrology, camera calibration, optical character recognition and texture extraction or synthesis. This paper proposes a method for estimating the rectification homography of a world plane that pertains to a single view containing the images of at least two circles in general position. The method does not presuppose that the circles radii, the camera´s intrinsics or the plane´s vanishing line are known and can simultaneously accommodate multiple circles. Comparative experimental results demonstrate the approach´s efficacy.
