1. a kind of method of locating terminal, which is characterized in that be used for location-server, which comprisesThe region division that the location-server is managed is n sub-regions, each corresponding grid of the subregion, describedN is the integer greater than 1;

  • The map reference that each grid is determined according to the map coordinate information prestored, it is corresponding with map reference to obtain gridRelationship;

    The characteristic information for acquiring each grid, obtains the corresponding relationship of grid and characteristic information;

    Characteristic information is established according to the corresponding relationship of the corresponding relationship of the grid and map reference, the grid and characteristic informationWith the corresponding relationship of map reference;

    The global position system GPS data that any terminal is sent are received, the GPS data is described in any terminal receivesIt is sent after GPS data, the GPS data includes coordinate data and supplemental characteristic information;

    The coordinate data is converted into target map coordinate;

    The corresponding relationship of the supplemental characteristic information and the target map coordinate is added to the characteristic information and map is satIn target corresponding relationship;

    Receive the image data that target terminal is sent;

    According to described image data, target signature information is obtained, the target signature information is for characterizing the target terminal weekThe environmental characteristic of surrounding environment;

    The corresponding relationship for inquiring preset characteristic information and location information determines the corresponding target position of the target signature informationThe corresponding relationship of information, the characteristic information and location information includes the corresponding relationship of the characteristic information and map reference;

    The target position information is sent to the target terminal.
