Title
(EN) APPARATUS AND METHOD FOR REJECTING ERRONEOUS OBJECTS OF EXTRUSION IN POINT CLOUD DATA
(FR) APPAREIL ET PROCÉDÉ DE REJET D'OBJETS D'EXTRUSION ERRONÉS DANS DES DONNÉES DE NUAGE DE POINTS
Abstract
(EN)
A method of rejecting the presence of an object of extrusion within a point cloud. The method comprising receiving, through a data interface, data describing a set of measurements of observed portions of the one or more objects in the scene. The method further comprising receiving data describing an extruded object that is hypothesized to exist in the scene. The method further comprising finding a set of near measurement points comprising measurement points wherein each measurement point is within a predefined distance of the hypothesized extruded object. The method further comprising classifying points within the set of near measurement points associated with the hypothesized extruded object as on-surface or off-surface. The method further comprising rejecting the hypothesized extruded object whose off-surface measurement points exceed an allowable threshold.

La présente invention concerne un procédé de rejet de la présence d'un objet d'extrusion dans un nuage de points. Le procédé comprend la réception, par le biais d'une interface de données, de données décrivant un ensemble de mesures de parties observées du ou des objets dans la scène. Le procédé comprend en outre la réception de données décrivant un objet extrudé qui est supposé exister dans la scène. Le procédé comprend en outre la recherche d'un ensemble de points de mesure proches comprenant des points de mesure dans lesquels chaque point de mesure se trouve à l'intérieur d'une distance prédéfinie de l'objet extrudé supposé. Le procédé comprend en outre le classement de points à l'intérieur de l'ensemble des points de mesure proches associés à l'objet extrudé supposé en tant que 'dans la surface' ou 'hors de la surface'. Le procédé comprend en outre le rejet de l'objet extrudé supposé dont les points de mesure 'hors de la surface' excèdent un seuil admissible.
