Building entrance determination method and device based on pedestrian track plotting

[0059] see figure 1 , figure 1 It is a schematic flowchart of a method for determining a building entrance based on pedestrian dead reckoning disclosed in an embodiment of the present invention; figure 1 As shown, the building entrance determination method based on pedestrian dead reckoning may include:

[0060] 101. Acquire GPS positioning information and pedestrian dead reckoning records sent by the mobile terminal, where the GPS positioning information and pedestrian dead reckoning records are obtained when the mobile terminal enters the room from the outside.

[0061] Wherein, the executor of the embodiment of the present invention is an apparatus for determining a building entrance based on pedestrian dead reckoning, and the apparatus may be a mobile terminal, other electronic equipment, or a server.

[0062] The above-mentioned GPS positioning information may be a positioning message, at least including the number of searched satellites, signal strength, satellite distrib

[0097] see figure 2 , figure 2 It is a schematic flowchart of a method for determining a building entrance based on pedestrian dead reckoning disclosed in another embodiment of the present invention; figure 2 As shown, the building entrance determination method based on pedestrian dead reckoning may include:

[0098] 201-205.

[0099] Wherein, steps 201-205 are the same as steps 101-105 in the first embodiment, and will not be repeated here.

[0100] 206. Receive current GPS positioning information of the user equipment.

[0101] 207. Obtain the latitude and longitude coordinates of the current location according to the current GPS location information of the user equipment.

[0102] Wherein, when the user equipment needs positioning, it can send GPS positioning information, determine the current positioning latitude and longitude coordinates according to the GPS positioning information, and compare it with the recorded entrance latitude and longitude coordinate range to d
