Further, the operating system of the mobile terminal includes, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone8 operating system, and the like.
The following describes the technical solution of the present invention in detail with reference to specific embodiments from the perspective of a mobile terminal.
Example one
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for detecting a building entrance according to an embodiment of the present invention; as shown in fig. 1, the method for detecting the entrance of the building may include:
101. and the mobile terminal acquires positioning information by using a GPS in the process of entering and exiting the building.
The positioning information may be a positioning message, and at least includes the number of satellites, signal strength, satellite distribution information, and the like.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a GPS positioning accuracy variation curve during entrance and exit of a building according to an embodiment of the present invention. As can be seen from fig. 4, if the GPS positioning accuracy continuously changes with the change of the distance from the indoor space during the process of continuously positioning the building (indoor) by the GPS outside (outdoor), when the building (outdoor), the GPS signal is shielded less, the positioning accuracy is higher, and the positioning accuracy starts to change greatly at the inflection point of the building entrance position, and after passing through the building entrance position, the GPS positioning accuracy continuously decreases until the GPS signal is not searched. The process of continuously positioning from inside (indoor) to outside (outdoor) of the building through the GPS is just opposite to the above process, and specifically, the GPS positioning accuracy variation curve shown in fig. 4 can be referred to.
Based on the above description, implementation scenarios of the embodiments of the present invention include, but are not limited to, the following two types:
a1: a tester carries the mobile terminal to go in and out of a building and detect a building entrance so as to establish a building entrance fingerprint library and provide a good basis for accurately positioning the building entrance. Optionally, the mobile terminal starts a certain positioning software (such as a Baidu map, a Gade map, or a Google map) for positioning under the operation of the user, and further continuously acquires positioning information by using a GPS after the mobile terminal is positioned to the building.
A2: the user can open the function of automatically identifying the building entrance when in daily positioning or daily use, and can automatically identify the building entrance when the user goes in and out of the building entrance, so that an accuracy basis is provided for positioning the user.
With reference to the above description, further optionally, the obtaining, by the mobile terminal, the positioning information by using the GPS in the process of entering or exiting the building specifically may include: after the mobile terminal is positioned to a building, positioning information is acquired by using a GPS. In this embodiment, when a building is located, the positioning information can be continuously acquired by the GPS at a high speed to perform building entrance detection. For example, when the destination of the navigation is a building, after the building is located, the building has arrived near or at the entrance, and the GPS is used to perform building entrance location, so as to accurately detect the building entrance by using the characteristic that the GPS has a large change in location accuracy at the building entrance.
102. And the mobile terminal judges whether the positioning precision variation difference value in unit time is greater than or equal to a preset threshold value or not according to the acquired positioning information. When the positioning precision variation difference is greater than or equal to the preset threshold, turning to step 103; and when the positioning precision variation difference value is smaller than the preset threshold value, ending the process.
As can be seen from fig. 4, the GPS positioning accuracy changes greatly at the corner of the building entrance position, and according to this feature, in the embodiment of the present invention, a reasonable unit time may be preset, and the minimum variation difference of the GPS positioning accuracy at the building entrance position may be measured through a mass experiment and used as the preset threshold. Therefore, in the embodiment of the invention, the positioning information is continuously acquired through the GPS, and if the GPS positioning precision variation difference value in unit time is greater than or equal to the preset threshold value, the mobile terminal is positioned at the entrance position of the building, so that the entrance position of the building can be automatically identified through the mobile terminal.
As an optional implementation manner, the determining, by the mobile terminal, whether the difference of the positioning accuracy change in the unit time is greater than or equal to a preset threshold based on the obtained positioning information may specifically include: and the mobile terminal calculates a GPS positioning accuracy value according to the positioning information.
103. And the mobile terminal determines the position as the current entrance of the building and acquires the coordinate information of the current entrance.
And the coordinate information of the current entrance is longitude and latitude coordinate information.
Optionally, the mobile terminal acquires a building entrance name corresponding to the coordinate information, and then stores the coordinate indicated by the coordinate information and the target building entrance name in association with each other in a building entrance fingerprint database.
Further optionally, after obtaining the coordinate information, the mobile terminal sends the coordinate information to the positioning engine server, and the positioning engine server finds information of the target building according to the building name, obtains a building entrance name corresponding to the coordinate information, and then stores the coordinate indicated by the coordinate information and the building entrance name in the building entrance fingerprint library in an associated manner.
By implementing the embodiment of the invention, the entrance of the building can be automatically identified by utilizing the characteristic that the positioning accuracy of the GPS is influenced when the GPS passes through the entrance of the building, so as to establish the entrance fingerprint library of the building and provide a good basis for the positioning accuracy.
Example two
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for detecting a building entrance according to another embodiment of the present invention; as shown in fig. 2, the method for detecting the entrance of the building may include:
201. and the mobile terminal acquires positioning information by using a GPS in the process of entering and exiting the building.
202. And the mobile terminal judges whether the positioning precision variation difference value in unit time is greater than or equal to a preset threshold value or not according to the acquired positioning information. When the positioning accuracy variation difference is greater than or equal to the preset threshold, turning to step 203; and when the positioning precision variation difference value is smaller than the preset threshold value, ending the process.
203. And the mobile terminal determines the position as the current entrance of the building and acquires the coordinate information of the current entrance.
For more descriptions of steps 201-203, refer to the descriptions of steps 101-103 in the first embodiment, which are not repeated herein.
As an optional implementation manner, after acquiring the coordinate information of the current entrance, the mobile terminal determines whether to find a target entrance name corresponding to the current entrance based on a pre-stored association relationship between the entrance name of the building and the latitude and longitude information; when the target entry name is not found, executing step 204; and when the target entrance name is found, sending a positioning request carrying the coordinate information and the target entrance name to the positioning engine server, so that the positioning engine server indicates the position of the current entrance and correspondingly marks the target entrance name on a current positioning map of the mobile terminal. In the embodiment, the mobile terminal firstly stores the incidence relation between the entrance name and the latitude and longitude information of the building, and after the coordinate information of the current entrance is obtained, firstly determines whether the corresponding target entrance name can be found according to the incidence relation, if so, the positioning request carrying the coordinate information and the target entrance name is sent to the positioning engine server, and if not, the positioning request carrying the coordinate information is sent to the positioning engine server.
Further optionally, the mobile terminal may periodically obtain the association relationship between the entrance name of the building and the latitude and longitude information from the positioning engine server and store the association relationship. Therefore, the mobile terminal confirms the entrance name, and the positioning engine server only needs to complete the real-time display and labeling of the positioning map.
As another optional implementation manner, after obtaining the coordinate information of the current entrance, the mobile terminal finds the name of the target entrance corresponding to the current entrance based on the pre-stored association relationship between the entrance name and the latitude and longitude information, detects whether a location sharing command is received, and if receiving a location sharing instruction, obtains a map corresponding to the current location, indicates a location corresponding to the coordinate information on the map, marks the name of the target entrance, and shares the location sharing command with the chat object. Through the embodiment, the mobile terminal can not only automatically identify the building entrance, but also complete the indication of the building entrance on the map.
204. And the mobile terminal sends the positioning request carrying the coordinate information to the positioning engine server, so that the positioning engine server indicates the position of the current entrance in the current positioning map of the mobile terminal according to the coordinate information.
It should be noted that, if the mobile terminal performs positioning through a certain positioning software (such as a Baidu map, google map, or Goods map), the mobile terminal automatically identifies the current entrance of the building according to the change of the positioning accuracy of the GPS, and after obtaining the coordinate information of the current entrance, sends the positioning request carrying the coordinate information to the positioning engine server corresponding to the positioning software, and the positioning engine server can further indicate the coordinate position in the current your status map (i.e. the map corresponding to the positioning software) of the mobile terminal. In the implementation mode, the mobile terminal carries out building positioning through positioning software, further utilizes the GPS to detect the coordinate information of the entrance of the building, and finally completes the indication of the current entrance on the positioning map through the positioning engine server, so that the accurate positioning of the entrance of the building is realized. Optionally, the positioning engine server indicating the current portal in the positioning map may include: displaying a preset icon at a position corresponding to the coordinate information, and pointing to the preset icon through a color indication arrow beside the preset icon, or thickening or displaying the preset icon in color at the position corresponding to the coordinate information, and the like.
205. And the mobile terminal receives the current positioning map which indicates the position of the current entrance and is returned by the positioning engine server and outputs and displays the current positioning map.
As an optional implementation manner, when the current positioning map displayed by the mobile terminal is not marked with the entrance name of the building, step 204 may specifically include: the mobile terminal also sends a positioning request carrying the coordinate information to the positioning engine server, so that the positioning engine server obtains a target entrance name corresponding to the current entrance of the building according to the incidence relation between the entrance name and the latitude and longitude information of the building, and indicates the position of the current entrance and the corresponding labeled target entrance name on the current positioning map of the mobile terminal. In the embodiment, the entrance names of all entrances of a building are obtained in advance, longitude and latitude coordinates of all the entrances are measured, then an association relationship between the entrance names and the longitude and latitude information is established in a positioning engine, and further after the mobile terminal obtains the longitude and latitude coordinates of the current entrance, the positioning engine server further determines the entrance name of the current entrance, and marks the entrance name on the current positioning map, so that a user can know or the user can inform others of knowing the specific position of the entrance in the building.
Correspondingly, the mobile terminal receives the current positioning map which indicates the position of the current entrance and the name of the corresponding labeling target entrance and is returned by the positioning engine server, and outputs and displays the current positioning map. Therefore, the mobile terminal receives the current positioning map which indicates the position of the current entrance and is marked with the name of the target entrance and returned by the positioning engine server, and outputs and displays the current positioning map, so that the user can accurately know the current position of the user.
It can be seen that, in the above embodiment, the mobile terminal can automatically identify the entrance of the building, and then send the positioning request carrying the entrance to the positioning engine server, so that the server indicates the positioning location on the current positioning map in real time due to positioning, the mobile terminal receives the current positioning map and outputs and displays the current positioning map, and the entrance of the building is automatically identified by utilizing the characteristic that the positioning accuracy of the GPS is affected when the GPS passes through the entrance of the building, so as to provide a good basis for the positioning accuracy.

302. And the mobile terminal judges whether to search a target entrance position corresponding to the current longitude and latitude coordinates according to the corresponding relation between the entrance position of the building and the longitude and latitude coordinates which is stored in advance. When the target entry position is not found, the process goes to step 303, and when the target entry position is found, the process goes to step 306.
Wherein the entry location may be an entry name. In the embodiment of the invention, the mobile terminal stores the corresponding relation between the previously identified longitude and latitude coordinates and the entrance position, so as to establish the corresponding building entrance fingerprint database, thereby detecting whether the corresponding entrance position exists or not through the longitude and latitude coordinates when positioning is carried out later, and directly positioning if the corresponding entrance position exists, thereby improving the positioning speed.
303. The mobile terminal acquires positioning information using a GPS.
304. And the mobile terminal judges whether the positioning precision variation difference value in unit time is greater than or equal to a preset threshold value or not according to the acquired positioning information.

305. And the mobile terminal determines the position as the current entrance of the building and acquires the coordinate information of the current entrance.
306. And the mobile terminal indicates the position of the target entrance in the current positioning map according to the current longitude and latitude coordinates.
