Title
(EN) POSITIONING OF MOBILE OBJECT IN UNDERGROUND WORKSITE
(FR) POSITIONNEMENT D'OBJET MOBILE DANS UN CHANTIER SOUTERRAIN
Abstract
(EN)
According to an example aspect of the present invention, there is provided a method for positioning a mobile object in an underground tunnel, comprising: determining horizontal progression of a mobile object in an underground tunnel from a preceding position estimate or an initial position of the mobile object, determining horizontal position of the mobile object on the basis of a floor model of the tunnel and the estimated horizontal progression of the mobile object, and generating a three-dimensional position indicator on the basis of the horizontal position of the mobile object and a three-dimensional model of the tunnel.
(FR)
Selon un aspect de la présente invention donné à titre d'exemple, l'invention concerne un procédé de positionnement d'un objet mobile dans un tunnel souterrain, consistant à : déterminer la progression horizontale d'un objet mobile dans un tunnel souterrain à partir d'une estimation de position précédente ou d'une position initiale de l'objet mobile, déterminer la position horizontale de l'objet mobile sur la base d'un modèle de sol du tunnel et de la progression horizontale estimée de l'objet mobile et générer un indicateur de position tridimensionnelle sur la base de la position horizontale de l'objet mobile et d'un modèle tridimensionnel du tunnel.
