Abstract
(EN)
Systems and methods for managing a high-definition map. The system may include at least one storage device (340) configured to store point cloud data and instructions, and at least one processor (320) configured to execute the instructions to perform operations. The operations may include determining geographic coordinates of a point cloud (302) and associating the point cloud (302) with one or more map tiles of the high-definition map based on the geographic coordinates. For each of the one or more map tiles associated with the point cloud (302), the operations may also include generating a positioning point cloud block corresponding to the map tile based on at least a portion of the point cloud (302). The operations may further include providing the positioning point cloud block corresponding to at least one map tile to a client device based on information indicating a location of the client device.

La présente invention concerne des systèmes et des procédés de gestion d'une carte en haute définition. Le système peut comprendre un ou plusieurs dispositifs de stockage (340) conçus pour stocker des données de nuage de point et des instructions et un ou plusieurs processeurs (320) conçus pour exécuter les instructions de manière à effectuer des opérations. Les opérations peuvent consister à déterminer des coordonnées géographiques d'un nuage de points (302) et à associer le nuage de points (302) à un ou plusieurs secteurs de carte de la carte en haute définition sur la base des coordonnées géographiques. Pour chacun du ou des secteurs de carte associés au nuage de points (302), les opérations peuvent également consister à générer un bloc de nuage de points de positionnement correspondant au secteur de carte sur la base d'au moins une partie du nuage de points (302). Les opérations peuvent en outre consister à fournir à un dispositif client le bloc de nuage de points de positionnement correspondant à un ou plusieurs secteurs de carte, sur la base d'informations indiquant un emplacement du dispositif client.
