Title (EN) METHODS AND ASSOCIATED SYSTEMS FOR GRID ANALYSIS
(FR) PROCÉDÉS ET SYSTÈMES ASSOCIÉS POUR ANALYSE DE GRILLE
Abstract:
(EN) Methods of route planning for a moveable device and associated systems are disclosed herein. In representative embodiments, the method includes (1) downsampling a 3-D point cloud generated by a distance-measurement component of the movable device to obtain a downsampled point cloud; (2) extracting ground points from the downsampled point cloud; (3) analyzing the ground points in a surface-detecting direction; and (4) identifying an object based at least in part on the downsampled point cloud and the ground points. The identified object and the ground points can be used for planning a route for the moveable device.
(FR) L'invention concerne des procédés de planification d'itinéraire pour un dispositif mobile et des systèmes associés. Dans des modes de réalisation représentatifs, le procédé comprend les étapes qui consistent : (1) à sous-échantillonner un nuage de points 3D généré par un élément de mesure de distance du dispositif mobile pour obtenir un nuage de points sous-échantillonné; (2) à extraire des points au sol du nuage de points sous-échantillonné; (3) à analyser les points au sol dans une direction de détection de surface; et (4) à identifier un objet au moins en partie sur la base du nuage de points sous-échantillonné et des points au sol. L'objet identifié et les points au sol peuvent servir à planifier un itinéraire pour le dispositif mobile.
