*    GRAND Seminar


Vision Based Localization for Robots: metric, topological
and semantic mapping


Oct/12/2010, Tuesday noon-1:00pm. ENGR 4201


Ana Cris Murillo
Assistant Professor
Informatic and Engineering Systems Department
University of Zaragoza, Spain


In the last years, vision sensors have become widespread in many
development areas, including robotics, due to several advantages they
have with regard to other sensors. In this seminar, we will see some
computer vision methods applied in robotics to solve one of the basic
issues for any autonomous mobile device: to localize itself and to
localize and recognize elements around it. Vision based localization
can be solved at various semantic and abstraction levels. In
particular, we will see examples of metric localization, using
multi-view geometric constraints, topological localization/place
recognition approaches and recognition/localization of objects of
interest around the robot. Some of this examples, will be presented
with experiments run with catadioptric vision systems, very popular in
robotics fields, which provide wide field of view to the systems
thanks to a curved mirror placed in front of the camera.

*Short Bio*

Ana C. Murillo is assistant professor at the Department of Informatics
and System Engineering in the University of Zaragoza, Spain. In 2008,
she received the PhD in computer science from the University of
Zaragoza. She is working in the Robotics group of the same university,
and her research interests are in the area of computer vision applied
to robotics and autonomous systems, in particular multi-view geometry
applications and recognition tasks applied to semantic mapping.
