This paper presents a geometrical feature detection framework for use with conventional 2D laser rangefinders. This framework is composed of three main procedures: data pre-processing, breakpoint detection and line extraction. In data pre-processing,

We propose a weighted least-squares (WLS) algorithm for optimal pose estimation of mobile robots using geometrical maps as environment models. Pose estimation is achieved from feature correspondences in a nonlinear framework without linearization. Th

This paper deals with main apparent motion estimation using a fuzzy representation of a pixel's gray level. Rough histograms and possibility theory are used to provide an accurate estimation of the motion. The use of these theories allows us to partl

This paper presents a robust self-calibration method as well as results from experiments and simulations. The algorithm tracks points in an image sequence and exploits successive views in order to estimate the fundamental matrix and finally the intri

This paper introduces a decoupled approach of concurrent mapping and localization for mobile robots. Its theoretical aspects rely on recent techniques for correct uncertainty handling using stochastic models: covariance intersection and unscented tra

This paper presents a map-based navigation for autonomous underwater vehicles (AUV) that aims to enhance the localisation without external aid. Bathymetric profiles given by a multibeam echosounder are matched to a reference depth map (RDM). The RDM

The authors present a new segmentation method for range images consisting of a set of planar cross-sectional contours. The approach is novel in that it uses fuzzy criteria for grouping primitives and identifying homogeneous regions. The method was ap

A solution to extract 3-D shapes from a structured light image is presented. The 2-D striped image is segmented into regions corresponding to quadratic surfaces. A fuzzy analysis of the stripe's properties allows one to locate discontinuities and to
