[0016] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to help understanding, and should be considered as merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, in order to be clear and concise, the description below omits the description of well-known functions and mechanisms.

[0017] Figure 1 is a schematic diagram according to the first embodiment of the present disclosure. As shown in Figure 1 , the method of updating the point of interest of the present embodiment specifically includes the following steps:

[0018] S101, obtaining road information of a target traffic facility from a road network database.

[0019] The road network database used by the embodiment in the execution of S101 has different road information with different road attributes. The road attributes in the embodiment include at least one of road shape, road position, road name, and traffic facilities corresponding to the road, etc. The road attributes input by the input end can be used to obtain the corresponding road information from the road network database.

[0020] In the execution of S101, the embodiment can take a preset type of traffic facility as the target traffic facility, which includes at least one of toll station, service area, parking area, bridge, and other traffic facilities. In the execution of S101, the embodiment can also take the traffic facility actually selected by the input end in the road network as the target traffic facility.

[0021] The road information obtained by the embodiment in the execution of S101 is specifically the links and nodes in the real road network located in the periphery and / or inside the target traffic facility.

[0022] That is, if the target traffic facility is a toll station, the embodiment obtains the road information corresponding to one or more toll stations from the road network database, and updates the points of interest of the toll station type in the point of interest library. If the target traffic facility is a service area, the embodiment obtains the road information corresponding to one or more service areas from the road network database, and updates the points of interest of the service area type in the point of interest library.

[0023] Since the current road network database realizes the daily update of the changes in the real road network, the embodiment can realize the daily update of the points of interest in the online point of interest library, especially the points of interest of the traffic facility type, according to the road information obtained from the road network database.

[0024] S102, generating a target point of interest corresponding to the target traffic facility according to the road information.

[0025] After the embodiment obtains the road information of the target traffic facility from the road network database in the execution of S101, the embodiment generates a target point of interest corresponding to the target traffic facility according to the obtained road information in the execution of S102.

[0026] Specifically, when the embodiment generates a target point of interest corresponding to the target traffic facility according to the obtained road information in the execution of S102, an optional implementation manner that can be adopted by the embodiment is as follows: obtaining the center point coordinates corresponding to the obtained road information; taking the obtained center point coordinates as the position of the target point of interest corresponding to the target traffic facility, and taking the attribute of the target traffic facility as the attribute of the target point of interest corresponding to the target traffic facility.

[0027] The attribute of the target traffic facility in this embodiment includes at least one of the name, the opening state, the province to which the target traffic facility belongs, the facility purpose, and the update time of the target traffic facility.

[0028] That is, the embodiment obtains the position of the target interest point according to the obtained road information, and obtains the attribute of the target interest point according to the attribute of the target traffic facility, so as to automatically generate the target interest point corresponding to the target traffic facility according to the road network data, and improve the generation efficiency and the generation accuracy of the target interest point.

[0029] In the process of obtaining the center point coordinates corresponding to the obtained road information in S102, the embodiment can use an optional implementation manner as follows: determining the facility type of the target traffic facility; obtaining a coordinate determination method corresponding to the determined facility type; and obtaining the center point coordinates corresponding to the obtained road information by using the obtained coordinate determination method.

[0030] That is, the embodiment sets different coordinate determination methods for different traffic facilities, and then uses the obtained coordinate determination method corresponding to the determined facility type to obtain the center point coordinates, so as to improve the accuracy of the coordinates of the generated target interest point.

[0031] The facility type determined in S102 of the embodiment can be a specific type of the target traffic facility, such as a toll station, a service area, a bridge, etc. The facility type determined in S102 of the embodiment can also be a shape type corresponding to the target traffic facility, such as a point type (such as a toll station), a surface type (such as a service area or a parking area), a line type (such as a bridge), etc.

[0032] It can be understood that the embodiment can preset coordinate determination methods corresponding to different facility types, such as coordinate determination method 1 for generating the center point coordinates of the road information corresponding to the toll station (or the point type), coordinate determination method 2 for generating the center point coordinates of the road information corresponding to the service area or the parking area (the surface type), and coordinate determination method 3 for generating the center point coordinates of the road information corresponding to the bridge (the line type).

[0033] If the target traffic facility is a toll station, in the process of obtaining the center point coordinates corresponding to the obtained road information by using the determined coordinate determination method in S102, the embodiment can use an optional implementation manner as follows: determining the entry road section and the exit road section of the toll station according to the obtained road information; and taking the coordinates of the intersection between the determined entry road section and the exit road section as the center point coordinates corresponding to the obtained road information.

[0034] If the target traffic facility is a service area or a parking area, in the step S102, the optional implementation manner of the embodiment can be used to determine the center point coordinates corresponding to the obtained road information by using the determined coordinate determination method, which is as follows: according to the obtained road information, a road segment entering the service area or the parking area is taken as a first road segment; a road node is searched along the direction of the determined first road segment; in a case where the searched road node is a three-node (i.e., the road node contains three road segments), a road segment closest to the highway is extracted from the road segments corresponding to the road node as a second road segment; a road node is searched along the direction of the determined second road segment; in a case where the searched road node is a three-node (i.e., the road node contains three road segments), a road segment closest to the highway is extracted from the road segments corresponding to the road node as a third road segment; and the coordinates of the center point of the road segment string composed of the first road segment, the second road segment and the third road segment are taken as the center point coordinates corresponding to the obtained road information.

[0035] In the step S102, the embodiment can also take the coordinates of the position of the center point of the composed road segment string offset by a preset distance (for example, 10 m) in the opposite direction of the highway as the center point coordinates corresponding to the obtained road information after determining the center point of the composed road segment string.

[0036] In addition, if the embodiment fails to find a three-node road node in the step S102, the coordinates of the center point of the road segment closest to the highway in the road information can be directly taken as the center point coordinates corresponding to the obtained road information, thereby avoiding the problem that the target point of interest corresponding to the service area or the parking area cannot be generated.

[0037] If the target traffic facility is a bridge, in the step S102, the optional implementation manner of the embodiment can be used to determine the center point coordinates corresponding to the obtained road information by using the determined coordinate determination method, which is as follows: according to the obtained road information, a road segment corresponding to the bridge is determined; and the coordinates of the center point of the determined road segment are taken as the center point coordinates corresponding to the obtained road information.

[0038] That is, the embodiment presets different coordinate determination methods for different types of target traffic facilities, and then uses the corresponding coordinate determination method to obtain the center point coordinates of the coordinates as the target point of interest from the obtained road information, thereby improving the accuracy of the obtained center point coordinates.

[0039] It can be understood that in some application scenarios with low precision requirements, the embodiment can take the average of the coordinates of the center points of one or more road segments in the obtained road information as the center point coordinates corresponding to the obtained road information when performing S102 to obtain the center point coordinates corresponding to the obtained road information.

[0040] S103, determining a changed interest point according to the existing interest point and the target interest point, and obtaining an update state of the changed interest point.

[0041] After the embodiment performs S102 to generate the target interest point corresponding to the target traffic facility, S103 is performed to determine a changed interest point according to the existing interest point and the target interest point, and obtain an update state of the changed interest point.

[0042] The existing interest point in the embodiment is an interest point that already exists in the online interest point library; and the update state of the changed interest point obtained by the embodiment performing S103 is one of an addition state, a deletion state, and a modification state.

[0043] When the embodiment performs S103 to determine a changed interest point according to the existing interest point and the target interest point, and obtain an update state of the changed interest point, an optional implementation manner that can be adopted is as follows: performing location matching on the existing interest point and the target interest point; in a case where it is determined that the location of the target interest point is not contained in the location of the existing interest point, determining that the target interest point is a changed interest point, and setting the update state of the changed interest point to an addition state.

[0044] When the embodiment performs S103 to determine a changed interest point according to the existing interest point and the target interest point, and obtain an update state of the changed interest point, an optional implementation manner that can be adopted is as follows: performing location matching on the existing interest point and the target interest point; in a case where it is determined that the location of the existing interest point is not contained in the location of the target interest point, determining that the existing interest point is a changed interest point, and setting the update state of the changed interest point to a deletion state.

[0045] When the embodiment performs S103 to determine a changed interest point according to the existing interest point and the target interest point, and obtain an update state of the changed interest point, an optional implementation manner that can be adopted is as follows: performing location matching on the existing interest point and the target interest point; in a case where it is determined that the target interest point and the existing interest point located at the same location have different attributes, determining that the existing interest point is a changed interest point, and setting the update state of the changed interest point to a modification state.

[0046] That is, the embodiment determines the changed interest point in the target interest point or the existing interest point according to the position matching result obtained by matching the existing interest point with the target interest point, and respectively obtains the update state of the determined changed interest point, thereby improving the accuracy of the changed interest point and the update state thereof.

[0047] In addition, when determining the changed interest point and obtaining the update state of the changed interest point in S103, the embodiment can also simultaneously perform the above three methods to determine the changed interest point corresponding to different update states, thereby improving the comprehensiveness in updating the interest point.

[0048] In S104, the changed interest point is processed according to the update state of the changed interest point, and the updating of the interest point is completed.

[0049] After determining the changed interest point and obtaining the update state of the changed interest point in S103, the embodiment performs S104 to process the changed interest point according to the obtained update state of the changed interest point, thereby completing the updating of the interest point.

[0050] If the update state of the changed interest point is the increase state, when the embodiment performs S104 to process the changed interest point according to the update state of the changed interest point and completes the updating of the interest point, an optional implementation manner that can be adopted is to add the position and the attribute of the target interest point as the changed interest point to the online interest point library.

[0051] If the update state of the changed interest point is the deletion state, when the embodiment performs S104 to process the changed interest point according to the update state of the changed interest point and completes the updating of the interest point, an optional implementation manner that can be adopted is to delete the position and the attribute of the existing interest point as the changed interest point from the online interest point library.

[0052] If the update state of the changed interest point is the modification state, when the embodiment performs S104 to process the changed interest point according to the update state of the changed interest point and completes the updating of the interest point, an optional implementation manner that can be adopted is to replace the attribute of the existing interest point as the changed interest point in the online interest point library with the attribute of the target interest point.

[0053] That is, the embodiment generates the target interest point corresponding to the target traffic facility by using the road information obtained from the road network database, and then completes the updating of the interest point of the traffic facility type according to the existing interest point and the target interest point, thereby reducing the updating cost of the interest point and improving the updating efficiency, the updating comprehensiveness and the updating accuracy of the interest point.

[0054] Figure 2 is a schematic diagram according to the second embodiment of the present disclosure. As shown in Figure 2 The device 200 for updating the interest point of the embodiment includes:

[0055] The acquisition unit 201 is configured to acquire road information of a target traffic facility from a road network database.

[0056] The road network database used by the acquisition unit 201 has different road information with different road attributes, and the road attributes include at least one of road shape, road position, road name, and traffic facility corresponding to the road, etc. The acquisition unit 201 can acquire the corresponding road information from the road network database by inputting the road attribute input by the input terminal.

[0057] The acquisition unit 201 can take a preset type of traffic facility as the target traffic facility, and the preset type of traffic facility includes at least one of a toll station, a service area, a parking area, a bridge, etc. The acquisition unit 201 can also take the traffic facility actually selected by the input terminal in the road network as the target traffic facility.

[0058] The road information acquired by the acquisition unit 201 is specifically a link and a node in the real road network located around and / or inside the target traffic facility.

[0059] The generation unit 202 is configured to generate a target point of interest corresponding to the target traffic facility according to the road information.

[0060] After the acquisition unit 201 acquires the road information of the target traffic facility from the road network database, the generation unit 202 generates a target point of interest corresponding to the target traffic facility according to the acquired road information.

[0061] Specifically, when the generation unit 202 generates a target point of interest corresponding to the target traffic facility according to the acquired road information, an optional implementation manner that can be adopted by the generation unit 202 is as follows: obtaining a center point coordinate corresponding to the acquired road information; taking the obtained center point coordinate as the position of the target point of interest corresponding to the target traffic facility, and taking the attribute of the target traffic facility as the attribute of the target point of interest corresponding to the target traffic facility.

[0062] The attribute of the target traffic facility in the embodiment includes at least one of the name, the opening state, the province to which the target traffic facility belongs, the facility purpose, and the update time of the target traffic facility.

[0063] That is, the generation unit 202 obtains the position of the target point of interest according to the acquired road information, and obtains the attribute of the target point of interest according to the attribute of the target traffic facility, so as to achieve the purpose of automatically generating the target point of interest corresponding to the target traffic facility according to the road network data, and improve the generation efficiency and the generation accuracy of the target point of interest.

[0064] The optional implementation manner that the generation unit 202 can adopt when obtaining the center point coordinate corresponding to the obtained road information is: determining a facility type of the target traffic facility; obtaining a coordinate determination method corresponding to the determined facility type; and obtaining the center point coordinate corresponding to the obtained road information by using the obtained coordinate determination method.

[0065] That is, the generation unit 202 sets different coordinate determination methods for different traffic facilities, and then obtains the center point coordinate by using the obtained coordinate determination method corresponding to the determined facility type, which can improve the accuracy of the generated coordinate of the target point of interest.

[0066] The facility type determined by the generation unit 202 can be a specific type of the target traffic facility, such as a toll station, a service area, a bridge, etc. The facility type determined by the generation unit 202 can also be a shape type corresponding to the target traffic facility, such as a point type (such as a toll station), a surface type (such as a service area or a parking area), a line type (such as a bridge), etc.

[0067] If the target traffic facility is a toll station, the optional implementation manner that the generation unit 202 can adopt when obtaining the center point coordinate corresponding to the obtained road information by using the determined coordinate determination method is: determining an entry road section and an exit road section of the toll station according to the obtained road information; and taking the coordinate of the intersection between the determined entry road section and exit road section as the center point coordinate corresponding to the obtained road information.

[0068] If the target traffic facility is a service area or a parking area, the optional implementation manner that the generation unit 202 can adopt when obtaining the center point coordinate corresponding to the obtained road information by using the determined coordinate determination method is: taking a road section entering the service area or the parking area as a first road section according to the obtained road information; searching for a road node in the direction of the determined first road section; in a case where it is determined that the searched road node is a three-node (i.e., the road node contains three road sections), extracting a road section closest to the highway from the road sections corresponding to the road node as a second road section; searching for a road node in the direction of the determined second road section; in a case where it is determined that the searched road node is a three-node (i.e., the road node contains three road sections), extracting a road section closest to the highway from the road sections corresponding to the road node as a third road section; and taking the coordinate of the center point of a road section string composed of the first road section, the second road section, and the third road section as the center point coordinate corresponding to the obtained road information.

[0069] In the method, the generating unit 202 can also, when generating the coordinate of the center point of the road segment string composed of the first road segment, the second road segment and the third road segment as the coordinate of the center point corresponding to the obtained road information, offset the coordinate of the position of the center point of the composed road segment string by a preset distance (for example, 10 m) in the opposite direction of the highway, and then generate the coordinate as the coordinate of the center point corresponding to the obtained road information.

[0070] In addition, if the generating unit 202 fails to find the road node of the three nodes, the coordinate of the center point of the road segment closest to the highway in the road information can be directly generated as the coordinate of the center point corresponding to the obtained road information, so as to avoid the problem that the target interest point corresponding to the service area or the parking area cannot be generated.

[0071] If the target traffic facility is a bridge, when the generating unit 202 uses the determined coordinate determination method to generate the coordinate of the center point corresponding to the obtained road information, an optional implementation manner can be used, that is, the road segment corresponding to the bridge is determined according to the obtained road information, and the coordinate of the center point of the determined road segment is generated as the coordinate of the center point corresponding to the obtained road information.

[0072] That is, the generating unit 202 presets different coordinate determination methods for different types of target traffic facilities, and then uses the corresponding coordinate determination method to generate the coordinate of the center point of the target interest point from the obtained road information, so as to improve the accuracy of the generated coordinate of the center point.

[0073] It can be understood that in some application scenarios with low precision requirements, the generating unit 202 can generate the average of the coordinates of the center points of one or more road segments in the obtained road information as the coordinate of the center point corresponding to the obtained road information when generating the coordinate of the center point corresponding to the obtained road information.

[0074] The processing unit 203 is configured to determine a changed interest point according to the existing interest point and the target interest point, and obtain an update state of the changed interest point.

[0075] In the embodiment, the generating unit 202 generates the target interest point corresponding to the target traffic facility, and then the processing unit 203 determines a changed interest point according to the existing interest point and the target interest point, and obtains an update state of the determined changed interest point.

[0076] In the embodiment, the existing interest point is an interest point that already exists in an online interest point library, and the update state of the changed interest point obtained by the processing unit 203 is one of an addition state, a deletion state and a modification state.

[0077] The optional implementation of the processing unit 203 in determining the changed interest point according to the existing interest point and the target interest point and obtaining the update state of the changed interest point is as follows: the existing interest point is matched with the target interest point in position; and in a case where it is determined that the position of the target interest point is not contained in the position of the existing interest point, the existing interest point is determined as the changed interest point, and the update state of the changed interest point is set as the increase state.

[0078] The optional implementation of the processing unit 203 in determining the changed interest point according to the existing interest point and the target interest point and obtaining the update state of the changed interest point is as follows: the existing interest point is matched with the target interest point in position; and in a case where it is determined that the position of the existing interest point is not contained in the position of the target interest point, the existing interest point is determined as the changed interest point, and the update state of the changed interest point is set as the delete state.

[0079] The optional implementation of the processing unit 203 in determining the changed interest point according to the existing interest point and the target interest point and obtaining the update state of the changed interest point is as follows: the existing interest point is matched with the target interest point in position; and in a case where it is determined that the target interest point and the existing interest point located at the same position have different attributes, the existing interest point is determined as the changed interest point, and the update state of the changed interest point is set as the modification state.

[0080] That is, the processing unit 203 determines the changed interest point in the target interest point or the existing interest point according to the position matching result obtained by matching the existing interest point with the target interest point, and obtains the update state of the determined changed interest point, thereby improving the accuracy of the changed interest point and the update state thereof.

[0081] In addition, the processing unit 203 can also simultaneously execute the above three methods in determining the changed interest point and obtaining the update state of the changed interest point, so as to determine the changed interest points corresponding to different update states, thereby improving the comprehensiveness in updating the interest points.

[0082] The update unit 204 is configured to process the changed interest point according to the update state of the changed interest point, so as to complete the update of the interest points.

[0083] After the processing unit 203 determines the changed interest point and obtains the update state of the changed interest point, the update unit 204 processes the changed interest point according to the obtained update state of the changed interest point, so as to complete the update of the interest points.

[0084] If the update state of the changed interest point is the increase state, when the update unit 204 completes the update of the interest point by processing the changed interest point according to the update state of the changed interest point, an optional implementation manner that can be adopted is that the position and the attribute of the target interest point as the changed interest point are added to the online interest point library.

[0085] If the update state of the changed interest point is the deletion state, when the update unit 204 completes the update of the interest point by processing the changed interest point according to the update state of the changed interest point, an optional implementation manner that can be adopted is that the position and the attribute of the existing interest point as the changed interest point are deleted from the online interest point library.

[0086] If the update state of the changed interest point is the modification state, when the update unit 204 completes the update of the interest point by processing the changed interest point according to the update state of the changed interest point, an optional implementation manner that can be adopted is that the attribute of the existing interest point as the changed interest point in the online interest point library is replaced with the attribute of the target interest point.

[0087] That is, the update unit 204 adopts different processing methods according to different update states to perform the increase, deletion, or modification operation on the changed interest point, which can improve the accuracy of the update of the interest point.
