Abstract

The invention discloses a data fusion method and device, relates to the technical field of traffic information service, and solves the problems of incomplete coverage and low data quality of POI address information acquired by a single channel. According to the specific scheme, the method comprises the steps that a data fusion device obtains POI address information of each POI data source in at least two POI data sources to obtain an initial POI address information set, and the POI address information is used for representing position information of a geographic entity; pOI address informationincluded in the initial POI address information set is fused to obtain a target POI address information set, and the target POI address information set comprises multiple pieces of effective target POI address information; and the target POI address information included in the target POI address information set is loaded into an address information database.

Description

technical field [0001] The invention relates to the technical field of traffic information services, in particular to a data fusion method and device. Background technique [0002] Point of interest (POI) address information is a label for a specific geographic entity, representing a specific geographic location of the geographic entity. In practical applications, POI address information is closely related to economic and social activities and the daily life of the people, involving many aspects such as economic life, social communication, urban construction, and public security management. [0003] In related technologies, the POI address information of a geographic entity can be obtained from different channels, for example, it can be obtained from a public security network, an Internet application, and the like. However, the POI address information obtained by a single channel has the problems of incomplete coverage and low data quality. Contents of the invention [0...
