Abstract
(EN)
A method and device for constructing a high-resolution map, used for reducing the complexity of the high-resolution map. The method is: determining key points (301), the key points being used for describing information of key locations of lane attribute changes; determining a key point image layer on the basis of the positions of the key points and of the attributes of the key points (302); and determining a high-resolution map on the basis of a navigation map and of the key point image layer (303), where the navigation map is used for providing road-grade navigation information, and the high-resolution map is used for providing lane-grade navigation information.
(FR)
L'invention concerne un procédé et un dispositif de construction d'une carte à haute résolution, utilisés pour réduire la complexité de la carte à haute résolution. Le procédé consiste à : déterminer des points clés (301), les points clés étant utilisés pour décrire des informations d'emplacements clés de changements d'attributs de voie ; déterminer une couche d'image de points clés sur la base des positions des points clés et des attributs des points clés (302) ; et déterminer une carte à haute résolution sur la base d'une carte de navigation et de la couche d'image de points clés (303), la carte de navigation étant utilisée pour fournir des informations de navigation se rapportant à la route, et la carte à haute résolution étant utilisée pour fournir des informations de navigation se rapportant à la voie.
