Two-Dimensional and Three-Dimensional Computer Vision

Two-dimensional (2D) and three-dimensional (3D) computer vision employ the pinhole camera model, distortion models and general optimization procedures described in Chapter 3. For two-dimensional computer vision, it is assumed that the motions of a planar object occur within the object plane. In most 2D cases, the object plane is nominally parallel to the camera sensor plane. In 3D computer vision,1 the only restrictions placed on the motion of a curvilinear object are (a) the object remains in focus during the motion and (b) points of interest on the object are imaged onto two or more camera sensor planes. In the following sections, details regarding models and calibration procedures for 2D and 3D computer vision are provided.
