This paper presents a new set of equations for the self-calibration of a moving camera with
constant intrinsic parameters. Unlike most existing methods that require solving equations in …

We provide a completely new rigorous matrix formulation of the absolute quadratic complex
(AQC), given by the set of lines intersecting the absolute conic. The new results include …

We introduce a geometrical object providing the same information as the absolute conic: the
absolute line quadric (ALQ). After the introduction of the necessary exterior algebra and …

This purely theoretical work investigates the problem of artificial singularities in camera self-
calibration. Self-calibration allows one to upgrade a projective reconstruction to metric and …

Aiming at overcoming the difficulties derived from the traditional camera calibration methods
to record the underwater environment of a towing tank where experiments of scaled-model …

We present new results on the absolute line quadric (ALQ), the geometric object
representing the set of lines that intersect the absolute conic. We include new techniques for …

This work aims at introducing a new unified Structurefrom-Motion (SfM) paradigm in which
images of circular point-pairs can be combined with images of natural points. An imaged …

We address the problem of the recovery of Euclidean structure of a projectively distorted n-
dimensional space from the knowledge of the, possibly diverse, lengths of a set of segments …

We present new algorithms for the recovery of the Euclidean structure from a projective
calibration of a set of cameras with square pixels but otherwise arbitrarily varying intrinsic …

Cette thèse traite de la reconstruction tridimensionnelle d'une scène rigide à partir d'une
collection de photographies numériques, dites vues. Le problème traité est connu sous le …
