AutoCalib - Zhang's Camera Calibration

Camera Calibration : Estimating the parameters of a camera including focal length, distortion coefficients, and principle point.

Method

In this assignment, an automatic calibration method presented by Zhengyou Zhang[1] of Microsoft is implemented. The goal is estimate the the parameters fx, fy, cx, cy, k1, k2, where k1 and k2 are the radial distortion parameters and the camera calibration matrix (K) is given below:

K  = [[fx, 0, cx],
      [ 0, fy,cy],
      [ 0, 0,  1]]

The method relies on a calibration target (a checkerboard) to estimate the intrinsic parameters. The steps implemented is described at [2].
