Research in adaptative cruise control (ACC) is currently one of the most important topics in the field of intelligent transportation systems. The main challenge is to perceive the environment, especially at low speed. In this paper, we present a novel approach to track the 3D trajectory and speed of the obstacles and the surrounding vehicles through a(More)
Safe vehicle guidance under human or computer control requires a thorough understanding of the traversed environment. Consequently if perception systems are to be introduced into mass market vehicles as part of driving assistance systems, their proper operation throughout the vehicle working life is needed. Onboard stereo-vision systems can provide rich(More)
This paper presents a new formulation of place recognition in unknown environments. Many objects in indoor environments are likely to be moved. We want to make the most of several observations of a camera in the same scene to represent the different places and objects. We propose to combine methods of metrical and topological localization to detect and(More)
In this article we present a two dimensional edge extractor which gives the edge position in an image with a subpixelic precision. The method presented here gives a good accuracy with a low computational cost, and its implementation is very simple since it is derivated from the well-known Non-Maxima Suppression method [I, 3]. We also justify the method by(More)
