Abstract[English]
The present invention relates to a method for generating a lane boundary in an ego-vehicle ground truth system. The method includes: generating a lane boundary on the basis of received offline measurement data; predicting a position of a missing point in the lane boundary on the basis of positions of valid points in the lane boundary; and correcting and/or smoothing positions of respective points in the lane boundary on the basis of lane constraint conditions. The present invention further relates to an apparatus for generating a lane boundary in an ego-vehicle ground truth system, a computer storage medium, and a computer program product.[French]
La présente invention concerne un procédé de génération d'une limite de voie dans un système de réalité de terrain de véhicule EGO. Le procédé consiste à : générer une limite de voie sur la base de données de mesure hors ligne reçues ; prédire une position d'un point manquant dans la limite de voie sur la base de positions de points valides dans la limite de voie ; et corriger et/ou lisser des positions de points respectifs dans la limite de voie sur la base de conditions de contrainte de voie. La présente invention concerne en outre un appareil pour générer une limite de voie dans un système de réalité de terrain de véhicule EGO, un support de stockage informatique et un produit programme d'ordinateur.
