Abstract: An example system for identification of three-dimensional points includes a receiver to receive coordinates of a two-dimensional point in an image, and a set of calibration parameters. The system also includes a 2D-to-3D point identifier to identify a three-dimensional point in a scene corresponding to the 2D point using the calibration parameters and a non-central camera model including an axial viewpoint shift function comprising a function of a radius of a projected point in an ideal image plane.

Abstract: An example apparatus enabling a dual fisheye model and calibration is described. The apparatus includes at least one memory; and at least one processor to execute instructions to: generate a first set of coefficients for an inverse distortion polynomial, the inverse distortion polynomial indicative of radial distortion of an image captured by a camera; generate a second set of coefficients for an alternative distortion polynomial, the alternative distortion polynomial to enable identification of a first point in the image corresponding to a second point in a three-dimensional space represented by the image; and determine a location of the camera within the three-dimensional space based on at least one of the inverse distortion polynomial or the alternative distortion polynomial.

Abstract: An example system enabling a dual fisheye model and calibration is described. The system includes a calibration module that simultaneously generates a first set of coefficients of an inverse distortion polynomial f(ρ) representing radial distortion and a second set of coefficients of an alternative distortion polynomial g(ω). Further, the present techniques may also calibrate intrinsic and extrinsic parameters.

Abstract: Methods and apparatus to control appearance of views in free viewpoint media are disclosed. An apparatus includes at least one memory; instructions; and processor circuitry to execute the instructions to: determine a first point in three-dimensional space relative to a plurality of real-world cameras, the first point corresponding to a region of interest in a real-world scene to be captured by the real-world cameras; determine, independent of the first point, a second point in the three-dimensional space; and determine parameters for a virtual camera based on both the first point and the second point, the parameters to enable generation of a virtual image from a perspective of the virtual camera based on a modification of a real-world image captured by one of the real-world cameras.
