Abstract[English]
Systems and methods for panoptic segmentation of a point cloud are provided. A point cloud is projected into a range image. Features are extracted from the range image and generating a feature map from the extracted features. The feature map is downsampled and the features are scaled during downsampling using local geometry. Features are extracted from the downsampled feature map. The point cloud is semantically segmented at least partially based on the features extracted. Instances in the point cloud are segmented at least partially based on the features extracted.[French]
L'invention concerne des systèmes et des procédés de segmentation panoptique d'un nuage de points. Un nuage de points est projeté dans une image télémétrique. Des caractéristiques sont extraites de l'image télémétrique et une carte de caractéristiques est générée à partir des caractéristiques extraites. La carte de caractéristiques est sous-échantillonnée et les caractéristiques sont mises à l'échelle pendant un sous-échantillonnage à l'aide d'une géométrie locale. Des caractéristiques sont extraites de la carte de caractéristiques sous-échantillonnée. Le nuage de points est segmenté sémantiquement au moins partiellement sur la base des caractéristiques extraites. Les instances dans le nuage de points sont segmentées au moins partiellement sur la base des caractéristiques extraites.
