More Information
Summary:The invention relates to a method for generating a high definition 3D vector map for computer-implemented driver assistance of one or more autonomous vehicles, comprising successively: - one or more generations of at least one initial point cloud (50) of a route to be mapped by one or more acquisition vehicles, - the generation (10) of a classified point cloud (310) from the initial point cloud, the generation comprising: a first object type classification: ground and not ground from the initial point cloud (50), - a second classification (130) of a road or rail object type (132) from the ground object type, - a series of third classifications (210, ..., 270) of vegetation, building and infrastructure object types, from the not ground object type; based on the classified point cloud, identifying (20) unitary objects from the classified object types and the vectorisation of unitary objects, - storing vectorised data in a non-volatile memory.
