Catadioptric systems consist of the combination of lenses and mirrors. From them, central
panoramic systems stand out because they provide a unique effective viewpoint, leading to …

Motion estimation of vision-only has no absolute scale, which leads to unmeasurable scale
and scale drift. Existing methods of visual scale recovery are either costly or complex …

This paper proposes an approximate model of fisheye camera based on the optical
refraction. The model of fisheye lens is firstly derived from the optical refraction and the …

La Fotogrametría, como ciencia y técnica de obtención de información tridimensional del
espacio objeto a partir de imágenes bidimensionales, requiere de medidas de precisión y …

Aiming at the problem that the manipulator cannot grasp the object accurately when the
robot changes the position and pose of the object in the process of static grasping, a set of …

This study presents an approach for estimating the fisheye camera parameters using three
vanishing points corresponding to three sets of mutually orthogonal parallel lines in one …
