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.
