    Abstract: L'invention vise à fournir une architecture d'imageur laser à haute résolution spatiale, compatible avec une application embarquée à bord d'un véhicule, en particulier à bord d'un avion. Dans ce but, l'invention propose d'élaborer une information de télémétrie laser de type grand champ par une combinaison optique déportée adaptée. Un exemple d'équipement (1) selon l'invention embarqué dans un avion en déplacement dans un environnement susceptible de contenir des obstacles (4), en particulier d'un avion au sol, comporte un télémètre laser (11) couplé à une fibre optique (F1) d'émission d'impulsions laser (I), elle-même couplée à un système optique d'interface avec l'environnement (12) via un répartiteur optique (13) couplé à un faisceau de fibres optiques couvert sous forme d'illuminations laser (Fi). Un détecteur d'échos (14) des impulsions laser réfléchies par un obstacle (4) de l'environnement est en liaison avec une unité de traitement (15) des échos (Er), elle-même reliée à une centrale de données (16) relatives aux conditions de déplacement de l'avion et à un système d'affichage (17) des données de localisation d'obstacles (4).

    Abstract: During calibration of a network of multiple horizontally scanning range finders a measurement is performed with the range finders during movement of an object through an area covered by the network. For each of the range finders data sets are identified associated with the moving object based on a static analysis. An estimated relative transformation between respective poses of the range finders is determined for reach pair of overlapping range finders, based on the identified data sets of this pair. An initial maximum likelihood configuration of poses is determined based on the estimated relative transformations of each pair. In an iterative fashion with multiple iteration steps, sets of point correspondences of the data sets are determined based on a threshold condition. A maximum likelihood configuration of poses is determined based on the sets of point correspondences and on the maximum likelihood configuration determined in the previous iteration step or, in a first iteration step, on the initial maximum likelihood configuration.
