Camera Autocalibration and the Calibration Pencil


Valdés Morales, Antonio and Ronda Prieto, José Ignacio (2005) Camera Autocalibration and the Calibration Pencil. Journal of Mathematical Imaging and Vision, 23 (2). pp. 167-174. ISSN 0924-9907 (Print) 1573-7683 (Online)



We study the geometric object given by the set of lines incident
with the absolute conic. We see that this object is given by a pencil of quadrics
of P5, which is characterized. We describe some of its most relevant properties
for the camera autocalibration problem. Finally, we illustrate the applicabil-
ity of the theory proposing a linear algorithm for the metric upgrading of a
projective calibration of a set of ten or more cameras with varying parameters
and known skew and aspect ratio.
