Abstract: A method includes obtaining locations of n original track points P1 to Pn during a moving process of a mobile terminal. A time point at which the mobile terminal passes an ith original track point Pi in the n original track points P1 to Pn is earlier than a time point at which the mobile terminal passes an (i+1)th original track point Pi+1. The method also includes performing a filtering process on the n original track points P1 to Pn. The filtering process one or more of deletes at least one of then original track points P1 to Pn or updates a location of at least one of the n original track points P1 to Pn. The method further includes determining a moving track of the mobile terminal on at least one road included in a road map based on target track points obtained by performing the filtering process.
