Title (EN) METHOD AND APPARATUS FOR UNCERTAINTY MODELING OF POINT CLOUD
(FR) PROCÉDÉ ET APPAREIL DE MODÉLISATION D'INCERTITUDE DE NUAGE DE POINTS
Abstract:
(EN) A method and an apparatus for uncertainty modeling of point cloud and a non-transient storage medium. The method comprises: finding the neighboring points for each point; fitting a local quadratic surface for each point; generating a Gaussian Model (GM) for representing the uncertainty modeling of the local surface at each point. The present invention constructs the GMM piece-wisely on the underlying surface of point cloud, which will accurately model the surface uncertainty.
(FR) L'invention concerne un procédé et un appareil de modélisation d'incertitude de nuage de points et un support d'informations non transitoire. Le procédé consiste à : rechercher les points voisins de chaque point ; ajuster une surface quadratique locale de chaque point ; générer un modèle gaussien (GM) permettant de représenter la modélisation d'incertitude de la surface locale à chaque point. La présente invention permet de construire pas à pas le GMM sur la surface sous-jacente de nuage de points, ce qui permet de modéliser avec précision l'incertitude de surface.
