Conic tangents based high precision extraction method of concentric circle centers and its application in camera parameters calibration
A high-precision camera intrinsic parameters calibration method based on concentric circles was proposed. Different from Zhang’s method, its feature points are the centers of concentric circles. First, the collinearity of the projection of the center of concentric circles and the centers of two elli...
