Abstract[English]
Aligning a source and target model includes calculating a shape descriptor for a plurality of edge points, grouping the edge points by shape descriptor and selecting representative points for each group. Target and source point pair features (PPFs) are calculated between pairs of representative points on the target and source models, where PPFs defines the relative position and orientation of point pairs. Target PPFs are matched with each source PPF and the point pairs associated with the matched PPFs are transformed to align the location and edge direction of a target PPF point with the location and edge direction of a source PPF point. An angle is determined to align the second target PPF point with the second source PPF point, and a modal angle is found among the determined rotation angles. An output transformation is calculated using the transformations associated with the modal angle.[French]
L'alignement d'un modèle source et cible consiste à calculer un descripteur de forme pour une pluralité de points de bord, à regrouper les points de bord par descripteur de forme et à sélectionner des points représentatifs pour chaque groupe. Des caractéristiques de paires de points cible et source (PPF) sont calculées entre des paires de points représentatifs sur les modèles cible et source, les PPF définissant la position relative et l'orientation de paires de points. Des PPF cibles sont mises en correspondance avec chaque PPF source, et les paires de points associées aux PPF appariées sont transformées pour aligner l'emplacement et la direction de bord d'un point PPF cible avec l'emplacement et la direction de bord d'un point PPF source. Un angle est déterminé pour aligner le second point PPF cible avec le second point PPF source, et un angle modal est trouvé parmi les angles de rotation déterminés. Une transformation de sortie est calculée à l'aide des transformations associées à l'angle modal.
