Abstract: A data processing method is provided, the method including: obtaining crowd-sourced data, where each instance of the crowd-sourced data includes first location information of a terminal at a location point and received radio signal information, the location point is within a preset area, and the first location information indicates a relative location of the location point with respect to a preset location point; obtaining, based on the crowd-sourced data, a plurality of first similarities and a second similarity corresponding to each first similarity; determining a target mapping relationship based on the plurality of first similarities and the second similarity corresponding to each first similarity; and obtaining a plurality of preset trajectories within the preset area, and performing trajectory fusion on the plurality of preset trajectories with the target mapping relationship as a constraint, to obtain a trajectory fusion result.
