10 September 2009 High precision calibration method of intrinsic parameters for fish-eye cameras
Author Affiliations +
Fish-eye camera is suitable for 3D shape measurements at short range, because it has very wide depth of field and very wide angle of view. Most traditional calibration methods of the parameters for 3D shape measurements use a calibration chart drawn by white and black dual level lattices. However, edges of lattices are blurred by the influence of spatial LPF characteristics of image resolution. In this paper, we propose a high precision calibration method of the intrinsic parameters using slanting brightness lattice patterns with lower spatial frequency component.
