Title (EN) CORRECTION OF MOTION-BASED INACCURACY IN POINT CLOUDS
(FR) CORRECTION D'IMPRÉCISION BASÉE SUR UN MOUVEMENT DANS DES NUAGES DE POINTS
Abstract:
(EN) Correcting motion-based inaccuracy in point cloud data generated by one or more sensors carried by a scanning platform, and associated systems and methods are disclosed herein. A representative method includes associating a motion model with a target object of the point cloud, estimating adjusting factors based on the motion model, and adjusting scanning points in the point cloud using the adjusting factors.
(FR) L'invention concerne la correction d'une imprécision basée sur un mouvement dans des données de nuages de points générées par un ou plusieurs capteurs portés par une plateforme de balayage, et des systèmes et des procédés associés. Un procédé représentatif consiste à associer un modèle de mouvement à un objet cible du nuage de points, à estimer des facteurs d'ajustement sur la base du modèle de mouvement, et à ajuster des points de balayage dans le nuage de points à l'aide des facteurs d'ajustement.
