Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a diagram illustrating an application scenario of a map data fusion method according to an exemplary embodiment of the present invention. As shown in fig. 1, the map data fusion method provided by the present embodiment is applied to a server 2, where the server 2 may be a vehicle navigation data server, for example, a zebra map server. The server 2 is connected to the vehicle end 1 in a communication manner, and the server 2 may obtain POI data from different map data sources, for example, the server 2 may obtain POI information of the point of interest a from a first map data source 31, a second map data source 32, and a third map data source 33, respectively, where the first map data source 31 may be a hundred-degree map data source, the second map data source 32 may be a Tencent map data source, and the third map data source 33 may be a Gandd map data source.
The user may perform a search mode such as a peripheral search, a keyword search, a search along the way, or a code search on the vehicle terminal 1, for example, may search for "shanghai XXX restaurant," for which the corresponding POI information in the first map data source 31 may only be "address: XX zone XX way XX number "and" cuisine: XX cuisine ", while the corresponding POI information in the second map data source 32 may only be" address: XX area XX way XX number "and" average person consumption: XX ", whereas the corresponding POI information in the third map data source 33 may only have" address: XX area XX way XX number "and" offer information: XXXXX ". After receiving the search instruction, the vehicle end 1 reports the search instruction to the server 2, the server 2 determines the numbers of the interest points in different data sources according to the input interest point search instruction, such as "shanghai XXX restaurant", and the server 2 determines the numbers of the interest points in different data sources according to the interest point search instruction and the mapping relation table, and then obtains the detailed information corresponding to the interest points from different data sources according to the respective numbers, performs data fusion, and sends the detailed information to the terminal device, so that the terminal device can display comprehensive interest point detailed information, for example: "Shanghai XXX restaurant": "address: XX zone XX way XX number "," cuisine: XX cuisine "," average human consumption: XX "and" offer information: XXXXX ".
Fig. 2 is a flowchart illustrating a map data fusion method according to an exemplary embodiment of the present invention. As shown in fig. 2, the map data fusion method provided in this embodiment includes:
Specifically, at the server side, a first number of the interest point in the first map data source and a second number of the interest point in the second map data source are respectively determined according to the interest point information. It should be understood that the above-mentioned interest point information may be a name of an interest point or longitude and latitude information of the interest point, and the corresponding detail information of the same interest point in different data sources is also usually different, in order to be able to be established in the server, the corresponding relationship of the same interest point information in different data sources may be mapped in the form of a number, and the number may be a self-contained attribute of the interest point in the data source, or may be a separate number of the interest point by the server, and in this embodiment, the number is not specifically limited.
To better illustrate, an example may be made wherein the point of interest, "Shanghai XXX restaurant," has a first number of 10000001 in the first map data source and a second number of 20000001 in the second map data source.
And 102, the server establishes and stores a mapping relation table between the point of interest information and the first number and the second number.
After the server determines a first number of the point of interest in the first map data source and a second number of the point of interest in the second map data source according to the point of interest information, the server may further establish and store a mapping relationship table between the point of interest information and the first number and the second number.
In a possible implementation manner, based on the mapping relationship, fusion of all data of the point of interest in the two data sources can also be achieved, and synchronization with the databases of the data sources is performed regularly based on the mapping relationship, so that it is guaranteed that information after the point of interest fusion is the most up-to-date, for example, once per day.
For example, a mapping table of points of interest "Shanghai XXX restaurants" with a first number 10000001 in a first map data source, and a second number 20000001 in a second map data source is established.
And 103, the server receives the interest point searching instruction sent by the terminal equipment, and determines a first number and a second number according to the mapping relation table.
Specifically, an interest point search instruction input by a user is received at the terminal device, the interest point search instruction can be input by the user in a search mode of peripheral search, keyword search, along-the-way search, code point search and the like, and the terminal device sends the interest point search instruction to the server so that the server determines the first number and the second number according to the mapping relation table.
For example, the input point of interest search instruction may be "Shanghai XXX restaurant," and then the first number is 10000001 and the second number is 20000001 according to the mapping relationship table.
And step 104, the server acquires first detail information of the interest point from a first map data source according to the first number, acquires second detail information of the interest point from a second map data source according to the second number, and sends the first detail information and the second detail information to the terminal equipment.
Specifically, the server acquires first detail information of the interest point from a first map data source according to a first number, acquires second detail information of the interest point from a second map data source according to a second number, and sends the first detail information and the second detail information to the terminal device, so that the terminal device displays the first detail information and the second detail information. For example, point of interest first detail information may be obtained from a first map data source via a first number 10000001 and a second number 20000001 while point of interest second detail information may be obtained from a second map data source.
In this embodiment, a mapping relation table between the point of interest information and the first number and the second number is established and stored in the server, then when the server receives an interest point search instruction sent by the terminal device, the first number and the second number are determined according to the mapping relation table, the first detail information of the point of interest is obtained from the first map data source according to the first number, the second detail information of the point of interest is obtained from the second map data source according to the second number, and the first detail information and the second detail information are sent to the terminal device, so that the terminal device displays the first detail information and the second detail information, thereby realizing the fusion of the point of interest information in different map data sources, and presenting richer and comprehensive information to the user.
Fig. 3 is a schematic flow chart of a possible step 101 in the embodiment shown in fig. 2. For one possible implementation of the embodiment shown in fig. 2, as shown in fig. 3, step 101 in this embodiment includes:
And if the interest point information has the first number in the attribute of the first map data source, directly acquiring the number.
And if the interest point information has a second number in the attribute of the second map data source, directly acquiring the number.
Fig. 4 is another possible flow diagram of step 101 in the embodiment shown in fig. 2. For another possible implementation manner of the embodiment shown in fig. 2, as shown in fig. 4, step 101 in this embodiment includes:
If the attribute of the interest point information in the first map data source does not have the first number, the server allocates the first number in the first map data source for the interest point according to the interest point information.
And if the attribute of the interest point information in the second map data source does not have the second number, the server allocates the second number in the second map data source for the interest point according to the interest point information.
Fig. 5 is a flowchart illustrating a map data fusion method according to another exemplary embodiment of the present invention. As shown in fig. 5, the map data fusion method provided in this embodiment includes:
And step 204, the server acquires first detail information of the interest point from the first map data source according to the first number and acquires second detail information of the interest point from the second map data source according to the second number.
It should be noted that, the specific implementation manner of steps 201-204 in the present embodiment refers to the description of steps 101-104 in the embodiment shown in fig. 2, and is not described herein again.
And step 205, the server generates third detail information of the interest point according to the first detail information of the interest point and the second detail information of the interest point.
Since information of different data sources from the same point of interest usually has partial repetition, if the information is directly displayed in an overlapping manner according to the first detailed information of the point of interest and the second detailed information of the point of interest, some information can be repeatedly displayed, which is not beneficial for a user to read and the information is excessively redundant. Therefore, before the server sends the information to the terminal device, data fusion can be performed, and third detail information of the interest point can be generated according to the first detail information of the interest point and the second detail information of the interest point.
Specifically, the server generates third detail information of the point of interest according to the first detail information of the point of interest and the second detail information of the point of interest, where the server first determines whether the first sub information in the second detail information of the point of interest belongs to the first detail information of the point of interest, and if the determination result is negative, the server generates the third detail information of the point of interest according to the first detail information of the point of interest and the first sub information of the point of interest.
And step 206, the server sends the third detail information to the terminal equipment so that the terminal equipment displays the third detail information.
