Flexible Camera Calibration by Viewing a Plane from Unknown Orientations

  title={Flexible Camera Calibration by Viewing a Plane from Unknown Orientations},
  author={Zhengyou Zhang},
We propose a flexible new technique to easily calibrate a camera. It only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known. Radial lens distortion is modeled. The proposed procedure consists of a closed-form solution, followed by a nonlinear refinement based on the maximum likelihood criterion. Both computer simulation and real data have been used to… CONTINUE READING
