This chapter covers the following recipes:
- Pinhole camera model calibration
 - Fisheye camera model calibration
 - Stereo rig calibration - estimation of extrinsics
 - Distorting and undistorting points
 - Removing lens distortion effects from an image
 - Restoring a 3D point from two observations through triangulation
 - Finding a relative camera-object pose through the PnP algorithm
 - Aligning two views through stereo rectification
 - Epipolar geometry - computing fundamental and essential matrices
 - Essential matrix decomposition into rotation and translation
 - Estimating disparity maps for stereo images
 - Special case 2-view geometry - estimating homography transformation
 - Planar scene - decomposing homography into rotation and translation
 - Rotational camera cas - estimating camera rotation from homography
