Abstract: A method for fusing map data, includes: obtaining two-dimensional map data and three-dimensional map data to be fused; classifying the three-dimensional map data according to map data types, the map data types including line data, surface data, and traffic body data; performing elevation conversion for each type of three-dimensional map data according to an elevation conversion algorithm preset for each type of three-dimensional map data, to obtain a relative elevation of each type of three-dimensional map data; and fusing the two-dimensional map data and three-dimensional map data to be fused based on the relative elevation of each type of three-dimensional map data, to obtain fused data.

Abstract: The present disclosure provides an object association method and apparatus, and an electronic device, which relate to the technical field of maps. A specific implementation solution is: when performing object association, extracting first description information of each of a plurality of first objects from real data, and extracting second description information of each of a plurality of second objects from high-definition map data; and determining, according to the first description information and the second description information, association probabilities between the first objects and the second objects; then determining, according to the association probabilities between the first objects and the second objects, an association result of the first objects and the second objects, thus realizing automatic associations between objects in real world and objects in a high-definition map, and improving an association efficiency of objects.
