    A review and analyses of plumb-line calibration 
    Lerma García, José Luis; Cabrelles López, Miriam (Wiley: 12 months, 2007)
    [EN] Radial and decentring distortion parameters have long been reported as fundamental elements in camera calibration, especially in digital close range photogrammetry. This paper reports on an investigation for the ...

    Accurate calibration with highly distorted images 
    Ricolfe Viala, Carlos; Sánchez Salmerón, Antonio José; Martínez Bertí, Enrique (Optical Society of America, 2012)
    Camera calibration is a two-step process where first a linear algebraic approximation is followed by a nonlinear minimization. The nonlinear minimization adjusts the pin-hole and lens distortion models to the calibrating ...

    Calibration of a wide angle stereoscopic system 
    Ricolfe Viala, Carlos; Sánchez Salmerón, Antonio José; Martínez Bertí, Enrique (Optical Society of America, 2011)
    Inaccuracies in the calibration of a stereoscopic system appear with errors in point correspondences between both images and inexact points localization in each image. Errors increase if the stereoscopic system is composed ...

    Efficient lens distortion correction for decoupling in calibration of wide angle lens cameras 
    Ricolfe Viala, Carlos; Sánchez Salmerón, Antonio José; Valera Fernández, Ángel (Institute of Electrical and Electronics Engineers (IEEE), 2013-02)
    In photogrammetry applications, camera parameters must be as accurate as possible to avoid deviations in measurements from images. Errors increase if wide angle lens cameras are used. Moreover, the coupling between intrinsic ...

    Using the camera pin-hole model restrictions to calibrate the lens distortion model 
    Ricolfe Viala, Carlos; Sánchez Salmerón, Antonio José (Elsevier, 2011-09)
    Camera calibration required the computation of camera pin-hole and lens distortion models. The lens distortion is estimated alone or together with the pin-hole model, by using some existing lens distortion non-metric or ...
