Embodiment one

Referring to Fig. 2, an embodiment of the present invention provides a method for processing an indoor electronic map, and the method flow includes:

Step 200. Acquire pre-stored user key, service key and map product key. The indoor electronic map is an indoor electronic map with offset coordinates.

Among them, the user key is used to indicate whether the user of the mobile terminal has obtained the right to use the indoor electronic map; the service key is used to represent the operator who issued the indoor electronic map to the authorized user; the map product key is used to When an operation to change the map occurs, determine whether the changer of the map has permission to modify the map.

Furthermore, the user key and the service key are generated by a key generator, and the map product key is formed by binding the map identifier and the user key.

Wherein, the coordinate-shifted indoor electronic map is obtained when the operator authorizes the user to purchase the indoor map by offsetting the overall coordinates of the indoor electronic map according to a preset coordinate shift amount.

Step 201, according to the obtained user key, service key and map product key, perform coordinate deviation correction operation on the indoor electronic map with coordinate deviation.

Specifically, in order to correct the deviation of the indoor electronic map whose coordinates are offset, firstly, the encrypted data stored in advance including the coordinate offset is decrypted through the obtained user key, service key and map product key, and then the decrypted Negate the obtained coordinate offset to obtain the coordinate correction amount, and finally move the coordinate system of the coordinate-shifted indoor electronic map according to the obtained coordinate correction amount, and complete the correction operation for the coordinate-shifted indoor electronic map.

Wherein, in this embodiment, the method of calculating the coordinate offset by three keys is not limited, and the above-mentioned negative calculation is only one of many ways of calculating the coordinate offset by three keys, and Other existing calculation methods can be used to calculate the coordinate offset through the three keys, which will not be repeated here.

Step 202, displaying the user's location on the indoor electronic map after the coordinate deviation correction operation has been completed.

Specifically, the user's location information is obtained in advance, and then the obtained user location information is converted into the coordinate information of the indoor electronic map, and the user's location is displayed on the indoor electronic map after the coordinate correction operation is completed according to the converted coordinate information.

Through the above description, in the process of using the indoor electronic map, only the correct user key, service key and map product key can eliminate the coordinate offset of the indoor electronic map, so that authorized users can use the indoor map without coordinate offset Accurate positioning of the electronic map; and the coordinate offset of the indoor electronic map cannot be eliminated through the wrong user key, service key and map product key, so the indoor electronic map cannot be used by unauthorized users to locate the user. for accurate positioning.

Embodiment two

Referring to Fig. 3, an embodiment of the present invention provides a method for processing an indoor electronic map, and the method flow includes:

Step 300, the mobile terminal obtains the pre-stored user key, service key and map product key, and the indoor electronic map is an indoor electronic map with offset coordinates.

Specifically, when the user of the indoor electronic map wants to know his location through the indoor electronic map, he triggers an instruction to display the user's location on the indoor electronic map through the input device of the mobile terminal. After the instruction to display the user's location on the map, the user key, service key and map product key are obtained from the database that stores the user key, service key and map product key in advance.

Wherein, the input device of the mobile terminal includes but not limited to: buttons, touch screen and microphone.

The operator first offsets the coordinates of the indoor electronic map that has not been delivered to the user through the preset coordinate offset. The product key encrypts the coordinate offset of the indoor electronic map to form encrypted data including the coordinate offset of the indoor electronic map. Finally, the encrypted data, as well as the user key, service key and map product key, and the coordinate offset The mobile indoor electronic map is sent to the user. The user's mobile terminal receives the encrypted data, key and indoor electronic map sent by the operator, and then stores the encrypted data and indoor electronic map in the storage device, and saves the key in a database preset in the mobile terminal storage device.

Optionally, the method of generating the coordinate offset through the user key, service key and map product key is not limited to the above description, and the operator can also use other existing methods to generate the coordinate offset through the three keys quantity, and will not be repeated here.

Step 301, the mobile terminal performs a coordinate deviation correction operation on the indoor electronic map with offset coordinates according to the acquired user key, service key and map product key.

Specifically, the process of step 301 is specifically described by steps 3011-3013.

Step 3011, the mobile terminal decrypts the encrypted coordinate offset of the indoor electronic map according to the acquired user key, service key and map product key, to obtain the coordinate offset of the indoor electronic map.

Specifically, after obtaining the user key, service key and map product key, the mobile terminal obtains the encrypted data including the coordinate offset of the indoor electronic map from its own storage device, and then uses the inverse algorithm of the encryption algorithm to pass the user The secret key, the service key and the map product key decrypt the encrypted data including the coordinate offset of the indoor electronic map to obtain the coordinate offset of the indoor electronic map.

Among them, only through the correct user key, service key and map product key can the encrypted data be decrypted, and the correct coordinate offset of the indoor electronic map can be obtained; and through the wrong user key, service key and map If the product key decrypts the encrypted data, it is impossible to obtain the accurate coordinate offset to correct the deviation of the indoor electronic map.

Step 3012, the mobile terminal performs a negative operation on the coordinate offset of the decrypted indoor electronic map to obtain the coordinate correction amount.

Specifically, the coordinate system used by the indoor electronic map is generally a two-dimensional coordinate system or a three-dimensional coordinate system, then the form of the coordinate offset is generally (X, Y) or (X, Y, Z), then the mobile terminal takes the coordinate offset The negative number of the coordinate value in the offset forms the coordinate correction amount (-X,-Y) or (-X,-Y,-Z).

Among them, the correct coordinate offset of the indoor electronic map can obtain the coordinate correction amount to eliminate the coordinate offset of the indoor electronic map; while the wrong coordinate offset of the indoor electronic map can only obtain the coordinates that cannot eliminate the coordinate offset of the indoor electronic map Correction amount.

Step 3013, the mobile terminal performs a coordinate deviation correction operation on the indoor electronic map with coordinate deviations according to the obtained coordinate deviation correction amount.

Specifically, after obtaining the coordinate correction amount of the indoor electronic map, the mobile terminal moves the coordinate correction amount ((-X, -Y) or (-X, -Y ,-Z)), that is, take the coordinate system of the indoor electronic map as a two-dimensional Cartesian coordinate system as an example: move the abscissa of the origin coordinate of the two-dimensional Cartesian coordinate system to -X, and move the vertical coordinate of the origin coordinate of the two-dimensional Cartesian coordinate system After moving -Y, the coordinate correction operation for the coordinate offset indoor electronic map is completed.

Among them, for the indoor electronic map with coordinate deviation, only the coordinate deviation correction operation based on the correct coordinate deviation correction amount can eliminate the coordinate deviation of the indoor electronic map, but the coordinate deviation correction operation through the wrong coordinate deviation correction value cannot be eliminated The coordinates of the indoor electronic map are offset.

Step 302, the mobile terminal displays the user's location on the indoor electronic map after the coordinate deviation correction operation has been completed.

Specifically, the mobile terminal first obtains the user's location information through the preset indoor positioning module, then converts the obtained user location information into the coordinates of the indoor electronic map, and finally displays the transformed coordinates on the indoor electronic map. The operation of displaying the user's location on the indoor electronic map.

Among them, for authorized users who perform coordinate correction operations on the indoor electronic map through the correct user key, service key and map product key, the user's own location can be accurately displayed through the indoor electronic map that has completed the coordinate correction operation; However, for users who perform coordinate correction operations on indoor electronic maps through incorrect user keys, service keys, and map product keys, the indoor electronic map that has completed coordinate correction operations cannot accurately display the user's own location.

After using the indoor electronic map for a period of time, the user finds that the indoor electronic map lacks the map data of some places where the building has not been built for a long time, so that the indoor electronic map cannot provide users with indoor positioning services or route services in these buildings that have not been built for a long time .

Further, in the embodiment of the present invention, referring to FIG. 4, the indoor electronic map processing method further includes the following steps:

Step 400, the mobile terminal sends map update request information to the server for issuing map update data, and the map update request information includes: authentication information for the server to authenticate the indoor electronic map.

Specifically, when the user wants to update the indoor electronic map, the user triggers an indoor electronic map update instruction through the input device of the mobile terminal, and the mobile terminal obtains the information of the indoor electronic map according to the indoor electronic map update instruction to generate indoor electronic map authentication information, and then The indoor electronic map authentication information is added to the header data of the update request information to form map update request information, and finally the generated map update request information is sent to the server for issuing map update data.

Wherein, the information of the indoor electronic map obtained by the mobile terminal includes but not limited to: map identification, storage device identification, user key and map product key; the map identification is preset in the statistical information of the indoor electronic map, and the storage device identification is preset In the system information of the mobile terminal; the statistical information of the indoor electronic map and the system information of the mobile terminal are stored in the storage device of the mobile terminal; The map identification is obtained, the storage device identification is obtained from the system information of the mobile terminal, and the user key and map product key are obtained from a database that pre-stores the user key, service key and map product key.

Further, for an indoor electronic map that is not updated for the first time, the information of the indoor electronic map acquired by the mobile terminal also includes the last update identifier; the last update identifier is pre-stored in the statistical information of the indoor electronic map, and the last update identifier Including but not limited to: whether the last update was successful, the time and content of the last update, and other data.

Wherein, the statistical information of the indoor electronic map includes not only the map logo and the last update logo, but also information related to the use of the indoor electronic map, such as the version number of the map and the number of times the map is used.

Further, the binding information composed of at least two items of the map identifier, the storage device identifier, the user key, the map product key and the last update identifier included in the information of the indoor electronic map is used as the authentication of the indoor electronic map. rights information.

Optionally, the authentication information of the indoor electronic map includes: binding information of the user key and the map product key.

Step 401, the mobile terminal receives the map update data sent by the server when it is determined that the indoor electronic map is authenticated according to the received authentication information.

Specifically, when updating map data, a schematic diagram of data interaction between the mobile terminal and the server is shown in Figure 5. It can be seen from Figure 5 that the mobile terminal sends the authentication information of the indoor electronic map to the map update server. After uploading the data to the server, the server first judges whether there is a map update, if so, first obtains the pre-stored authentication information list, and checks whether there is any piece of authentication information in the authentication information list that is consistent with the received authentication information. Consistent authentication information entries. If there is an authentication information entry consistent with the received authentication information in the authentication information list, it means that the indoor electronic map that sent the map update request has passed the authentication of the server and is authorized. For the indoor electronic map, the server can send map update data to the mobile terminal where the indoor electronic map is located. If the server does not find an authentication information entry consistent with the received authentication information in the authentication information list, then return map update failure information to the mobile terminal where the indoor electronic map that sent the authentication information is located. If the server judges that there is no map update, it will return map update failure information to the mobile terminal where the indoor electronic map that sent the map update request information is located.

Wherein, when the server sends the encrypted data, key and indoor electronic map to the authorized user, it binds the data used to authenticate the indoor electronic map to form the authentication information of the indoor electronic map, and then sends the bound The formed authentication information is stored in the preset authentication information list.

Among them, the data used to authenticate the indoor electronic map includes but is not limited to: map identification, storage device identification, user key, map product key, storage device identification and last update identification; at least any two of these data Binding is performed to form the authentication information of the indoor electronic map, which is stored in the server.

Further, after the server determines that the indoor electronic map that sends the map update request is an authorized indoor electronic map, it can continue to judge whether the authorization period of the user corresponding to the user key carried in the authentication information sent by the indoor electronic map has expired. , if it is determined that the authorization period of the user corresponding to the user key has not expired, the server sends map update data to the mobile terminal where the indoor electronic map that sends the user key is located.

For example: Some operators stipulate that the update of the indoor electronic map needs to charge a fee, and the charged fee is deducted from the user's account balance when the indoor electronic map is updated, then the user key carried in the authentication information corresponds to the user's When judging whether the authorization period has expired, it can be judged whether the user's authorization period has expired based on whether the user's account balance corresponding to the user key can satisfy a map update. If the user's account balance at this time is greater than the map update fee, If it is determined that the user’s authorization period corresponding to the user key is still valid and has not expired, the server first deducts the fee for updating the map from the user’s account balance, and then sends the map update data to the indoor electronic map corresponding to the user key. in the mobile terminal. If the user's account balance corresponding to the user key is less than the fee to be deducted for map update, the server sends a recharge prompt message to the mobile terminal where the indoor electronic map corresponding to the user key is located, and after the user recharges the account and the user's When the account balance is greater than the fee to be deducted for map update, the map update fee will be deducted from the account balance, and the map update data will be sent to the mobile terminal where the indoor electronic map corresponding to the user key is located; if the user refuses to recharge the account, then If it is determined that the authorization period of the user corresponding to the user key is invalid, return map update failure information to the mobile terminal where the indoor electronic map corresponding to the user key is located.

Of course, the server can also determine whether the authorization period of the user corresponding to the user key carried in the authentication information sent by the indoor electronic map has expired by setting the validity period or update times of the map update, and other existing determination means. Judgment, I won't repeat them one by one here.

Step 402, the mobile terminal updates the indoor electronic map according to the received map update data sent by the server.

Specifically, after receiving the update data of the map, the mobile terminal writes the update data of the map that supplements the map data that has not been updated into the data of the indoor electronic map according to the update data of the map obtained, and writes the update data of the map that is not updated The map update data used for modifying the map data replaces the existing data in the indoor electronic map to complete the update operation of the indoor electronic map.

Through the description of steps 400-402, before updating the indoor electronic map, the mobile terminal collects the information of the indoor electronic map to form the authentication information of the indoor electronic map, and then sends the authentication information of the indoor electronic map to the server. The indoor electronic map authentication information sent by the terminal authenticates the indoor electronic map. Only when it is determined that the indoor electronic map that sent the update request passes the authentication, the server will send the update content to the mobile terminal where the indoor electronic map is located, completing the update of the indoor electronic map, and further protecting the interests of map producers and authorized users.

Based on the above description, the indoor electronic map processing method provided by the embodiment of the present invention uses the pre-stored user key, service key, and map product key to perform coordinate correction operations on the indoor electronic map with offset coordinates, and complete the correction The user's location is displayed on the indoor electronic map operated, and whether the user is an authorized user is verified through the user key, service key and map product key; during the use of the indoor electronic map, only the correct user key , service key, and map product key can eliminate the coordinate offset of the indoor electronic map, so that authorized users can use the indoor electronic map that eliminates the coordinate offset for accurate positioning; and through the wrong user key, service key, and map product The key cannot eliminate the coordinate offset of the indoor electronic map, so when an unauthorized user uses the indoor electronic map to locate the user, the indoor electronic map cannot accurately locate the user, thus avoiding unauthorized users to the indoor electronic map manufacturer and authorization as much as possible.
