Depth from the visual motion of a planar target induced by zooming

Robot egomotion can be estimated from an acquired video stream up to the scale of the scene. To remove this uncertainty (and obtain true egomotion), a distance within the scene needs to be known. If no a priori knowledge on the scene is assumed, the usual solution is to derive “in some way” the initial distance from the camera to a target object. This paper proposes a new, very simple way to obtain such a distance, when a zooming camera is available and there is a planar target in the scene. Similarly to “two-grid calibration” algorithms, no estimation of the camera parameters is required, and no assumption on the optical axis stability between the different focal lengths is needed. Quite the reverse, the non stability of the optical axis between the different focal lengths is the key ingredient that enables to derive our depth estimate, by applying a result in projective geometry. Experiments carried out on a mobile robot platform show the promise of the approach.Peer Reviewe

Comment soutenir la recherche doctorale : les doctorants, la littératie informationnelle et la formation à l’utilisation des bibliothèques

La littératie informationnelle est un élément essentiel de la recherche. Pour faire des recherches, il faut savoir trouver et gérer l’information scientifique d’une part, puis être capable de l’utiliser de façon responsable afin de créer un nouveau savoir d’autre part. La littératie informationnelle permet au chercheur de développer une disposition critique et de maîtriser les utilisations pratiques des technologies de l’information et des ressources dont il dispose.

An inextensible model for the robotic manipulation of textiles

We introduce a new isometric strain model for the study of the dynamics of cloth garments in a moderate stress environment, such as robotic manipulation in the neighborhood of humans. This model treats textiles as surfaces that are inextensible, admitting only isometric motions. Inextensibility is derived in a continuous setting, prior to any discretization, which gives consistency with respect to remeshing and prevents the problem of locking even with coarse meshes. The simulations of robotic manipulation using the model are compared to the actual manipulation in the real world, finding that the difference between the simulated and the real position of each point in the garment is lower than 1cm in average even when a coarse mesh is used. Aerodynamic contributions to motion are incorporated to the model through the virtual uncoupling of the inertial and gravitational mass of the garment. This approach results in an accurate, when compared to the recorded dynamics of real textiles, description of cloth motion incorporating aerodynamic effects by using only two parameters.Peer ReviewedPostprint (published version

Fagreferentkonferansen 2010 i Stavanger

Fagreferentkonferansen 2010 ble i år avholdt i Stavanger 31. mai - 2. juni i regi av Universitetsbiblioteket i Stavanger. Konferansen hadde tematisk spredd seg over "Fagreferentens roller", "Undervisning i biblioteket" og "E-bøker". Det var fagreferenter fra de norske høyere utdanningsinstitusjonene som selv som stod for det meste av det faglige innholdet Det er sammendragene av disse antatte bidragene som publiseres i dette spesialnummeret av NORIL
