In robot navigation, one of the important and fundamental issues is to reconstruct positions of landmarks or vision sensors locating around the robot. This paper proposes a method for reconstructing qualitative positions of multiple vision sensors from qualitative information observed by the vision sensors, i.e., motion directions of moving objects. The process iterates the following steps: (1)...

Multiple robot systems in which every robot is equipped with a vision sensor are more and more frequent. Most of these systems simply distribute the sensors in the environment, but they do not create a real Cooperative Distributed Vision System. In this paper we propose an approach to realize a Cooperative Distributed Vision System within a team of heterogeneous mobile robots. We present two re...

Having as a main motivation the development of robust and high performing robot vision systems that can operate in dynamic environments, we propose a context-based generic vision system for a mobile robot with a mobile camera. We choose as a first application for this vision system, the detection of static objects in the RoboCup Four Legged League domain. Preliminary results using real video se...
