Commonly, the detection of checkerboard calibration targets in images is carried out in a two-stage hierarchical fashion. The checkerboard plane and its four boundaries are exploited to estimate RC L and t C L, as demonstrated in Fig. 2). In the second step, the coarse localization is refined to sub-pixel accuracy. We perform camera, calibrations with different combinations of displays, cameras, and lenses, as well as with simulated images and find markedly lower reprojection errors when using active targets. A checkerboard pattern is a convenient calibration target. In our application, using a checkerboard calibration target is advantageous over using a pattern of dots. Calibration uses the interior vertex points of the checkerboard, so an "9x7" board uses the interior vertex parameter "8x6" as in the example below.
