The invention relates to a method of a control device of a first vehicle, having the steps of: receiving object information detected by means of a surrounding sensor and relating to a geographical object; determining the absence of a database entry in a database relating to the geographical object and corresponding to the object information; creating an information unit relating to the geographical object from the detected object information; and transmitting a verification request relating to the geographical object to a traffic infrastructure unit and / or a second vehicle together with the created information unit. The invention also relates to a method of a traffic infrastructure unit or a server, a control device of a vehicle, a control unit of a traffic infrastructure unit or a server, and a computer program.

The application provides a position determination method and device, relates to the technical field of data processing, and can realize conversion of address text into position information of a geographic space structure. The specific scheme comprises the following steps: firstly, address text is acquired; geographic entities and spatial relationship entities in the address text are extracted; the geographic entities represent geographic objects occupying spatial positions in a geographic space, and the spatial relationship entities represent spatial relationships between the geographic entities; and the geographic space position corresponding to the address text is determined according to the geographic entities and the spatial relationship entities.

The application discloses a geographic space-time modeling method, system, product, equipment and storage medium for twin space virtual-real interaction, abstracts geographic entities, sensors, geographic data, geographic models, rule knowledge, geographic objects and controllers in twin space virtual-real interaction into corresponding nodes respectively, constructs edges connecting the nodes according to predefined logical relationships between the nodes, and generates a semantic and logical expression model for twin space virtual-real interaction; based on a graph database and the semantic and logical expression model, node storage files of the nodes and edge storage files of the edges are constructed; based on an object-relational database, an object storage table is constructed; through a geographic object identifier, an association between an object node in the graph database and a geographic object table record in the object-relational database is established, and the problem of element fragmentation and process breakpoint in existing virtual-real interaction modeling is solved.

This invention belongs to the field of geospatial intelligent analysis methods, specifically a method for automatically constructing multi-scale dynamic spatiotemporal geographic maps based on vector data. It includes the following steps: S1, data standardization and basic spatial relationship calculation; S2, spatiotemporal integrated geographic entity modeling and map updating; S3, road network-enhanced spatial relationship modeling, integration, and map updating; S4, automatic construction of multi-scale geographic hierarchical systems and map updating; S5, map output. The execution of steps S1 to S4 is driven by an intelligent agent module, which dynamically adjusts the execution order and parameters of each step. This invention achieves end-to-end automated construction of geographic knowledge maps with dynamic spatiotemporal reasoning capabilities from multi-source, multi-period vector data, supports full lifecycle tracking of geographic objects, upgrades traditional geometric relationships to real and quantifiable path semantic relationships, and realizes cross-level spatial cognition and reasoning functions.
