A rapid and high-precision camera calibration technique based on active vision is proposed. A camera model and detailed analysis on the solution algorithm of its parameter are established. By in-plane translational motion of the camera,images of a hollow target plate are collected to calculate locations of the circular center. Meanwhile,the exact displacements of the camera are recorded;therefore the needed coordinates of the feature points in the object plane and in the correlative image plane are gained. Using these feature points,the camera calibration parameters can be calculated with a precision of 0.005 mm. Finally,automatic calibration is realized by use of the custom calibration module. The proposed method with less limiting conditions of camera motion basically realizes linear solution of the parameters of camera model,and provides an effective solution of camera calibration for active vision systems.
