Abstract

A matching algorithm and device for data with different scales based on global road network features are provided. The method includes: loading data of different maps, constructing crossroad groups in each map, and extracting information on attributes of the crossroad groups; allocating, according to the importance degree of the attribute information, weights for each attribute of the crossroad groups, and comprehensively evaluating confidence values of matching between two crossroad groups in different maps; and constructing, according to the confidence values, matched road networks, calculating total confidence values of the matched road networks, and selecting a road network with the highest total confidence value as an optimal matching solution, namely a matching result.
