[0045] Continue to refer Figure 2 , shows a process 200 of some embodiments of the method for generating map version information according to the present disclosure. The method for generating map version information comprises the following steps:
[0046] Step 201: in response to detecting that a point of interest information in a point of interest information set has changed, determining the changed point of interest information as target point of interest information.
[0047] In some embodiments, the execution subject of the map version information generation method (for example Figure 1 The electronic device 101 shown can determine the changed point of interest information as target point of interest information in response to detecting a change in the point of interest information in the point of interest information set. Among them, the point of interest information in the above-mentioned point of interest information set can be map data of a certain area point on the map. The point of interest information in the above-mentioned point of interest information set may include but is not limited to at least one of the following: point of interest identification, point of interest data, and point of interest change time. Here, the point of interest identification can uniquely determine a point of interest. The point of interest can be a certain area point on the map. For example, a certain area point can be but is not limited to: a building, a road, a community, etc. The point of interest data can be the map data corresponding to the point of interest on the map. The point of interest change time can be the time when the point of interest changes. For example, the point of interest identification can be but is not limited to: 1, 2, 3, etc. The point of interest change time can be but is not limited to: 2023 / 2 / 1, 2023 / 2 / 7.
[0048] Step 202: Determine a reference time and a reference version number based on the point of interest information set.
[0049] In some embodiments, the execution entity may determine a reference time and a reference version number based on the POI information set. The reference version number may be determined based on the reference time. In practice, first, the execution entity may determine the earliest POI change time among the POI change times included in the POI information in the POI information set as the reference time. Then, the execution entity may determine the preset initial version number as the reference version number corresponding to the reference time. For example, the preset initial version number may be 0. The reference time may be 2023 / 2 / 1.
[0050] Step 203: Generate target map version information based on the target point of interest information, the reference time and the reference version number.
[0051] In some embodiments, the execution entity may generate target map version information based on the target point of interest information, the reference time and the reference version number.
[0052] In practice, based on the target point of interest information, the reference time and the reference version number, the execution subject may generate the target map version information by the following steps:
[0053] In the first step, the difference between the interest point change time included in the target interest point information and the reference time is determined as the target difference.
[0054] In the second step, the sum of the target difference value and the benchmark version number is determined as the target point of interest version number.
[0055] In the third step, the POI identifier, POI data and the POI version number included in the target POI information are combined into target map version information.
[0056] Step 204: Add the target map version information to the map version information sequence corresponding to the preset map version information sequence set.
[0057] In some embodiments, the above-mentioned execution entity may add the above-mentioned target map version information to the map version information sequence corresponding to the preset map version information sequence set. Among them, the map version information in the preset map version information sequence set may be the map data of a certain area point on the map. The map version information sequence in the map version information sequence set corresponds to a point of interest. The map version information in the map version information sequence set may include but is not limited to at least one of the following: a point of interest identifier, a point of interest data, and a point of interest version number. Here, the point of interest identifier can uniquely identify a point of interest. The point of interest data may be the map data corresponding to the point of interest on the map. The point of interest version number may represent the version number of the map corresponding to the map version information. In practice, first, the above-mentioned execution entity may extract the map version information sequence corresponding to the point of interest corresponding to the above-mentioned target map version information from the map version information sequence set. Then, the above-mentioned execution entity may add the above-mentioned target map version information to the above-mentioned map version information sequence.
[0058] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the map version information generation method of some embodiments of the present disclosure, redundant storage of information can be avoided. Specifically, the reason for redundant storage of information is that the entire map version information is fully updated at regular intervals, and incremental updates are performed irregularly, resulting in the updated map version information being prone to duplicate information. Based on this, the map version information generation method of some embodiments of the present disclosure, first, in response to detecting that the interest point information in the interest point information set has changed, the changed interest point information is determined as the target interest point information. Thus, the target map version information can be generated based on the interest point information, so as to subsequently generate the target map version information without duplicate information with other map version information. Secondly, based on the above interest point information set, the reference time and the reference version number are determined. Among them, the above reference version number is determined according to the above reference time. Thus, the reference time and the reference version number can be obtained, so as to subsequently generate the target map version information. Then, based on the above target interest point information, the above reference time and the above reference version number, the target map version information is generated. Thus, the target map version information without duplicate information with other map version information can be obtained. Finally, the target map version information is added to the map version information sequence corresponding to the preset map version information sequence set. Thus, a map version information sequence set including a complete version of map version information without duplicate information can be obtained. Thus, redundant storage of information can be avoided.

[0063] Step 303: Generate target map version information based on the target point of interest information, the reference time and the reference version number.
[0064] In some embodiments, the execution subject of the map version information generation method (for example Figure 1The electronic device 101 shown generates target map version information based on the target interest point information, the reference time and the reference version number. The target interest point information may include but is not limited to at least one of the following: target interest point identifier, target interest point data and target interest point change time.
[0065] In practice, based on the target point of interest information, the reference time and the reference version number, the execution subject may generate the target map version information by the following steps:
[0066] The first step is to update the initial map version information in the map version information sequence corresponding to the target point of interest information in the map version information sequence set based on the target point of interest information, the reference time and the reference version number. The initial map version information may be the last map version information in the map version information sequence. The map version information in the map version information sequence set may include but is not limited to at least one of the following: point of interest map identifier, point of interest map data, point of interest start time, point of interest end time, point of interest start version number, point of interest end version number. The point of interest map identifier can uniquely identify a point of interest. The point of interest map data may be the map data corresponding to the point of interest on the map. The point of interest start time may be the time when the map corresponding to the map version information starts to take effect. The point of interest end time may be the time when the map corresponding to the map version information ends to take effect. The point of interest start version number may be the version number of the map corresponding to the map version information when the map version information starts to take effect. The point of interest end version number may be the version number of the map corresponding to the map version information when the map version information ends to take effect. The initial map version information may include but is not limited to at least one of the following: initial point of interest end time and initial point of interest end version number. For example, the map version information sequence set may refer to Figure 4 A schematic diagram of a map version information table according to the map version information generating method disclosed in the present invention is shown. Figure 4 The table headers in the map version information table shown may be "POI map identifier, POI map data, POI start time, POI end time, POI start version number, POI end version number".

Here, Figure 4The corresponding current time may be 2023 / 2 / 7. The map version information sequence may include Figure 4 401, 402 and 403 are shown. The map version information sequence may also include Figure 4 404 and 405 are shown.
[0067] In practice, based on the target POI information, the reference time and the reference version number, the execution subject may update the initial map version information in the map version information sequence corresponding to the target POI information in the map version information sequence set through the following sub-steps:
[0068] In a first sub-step, the target point of interest change time included in the target point of interest information is determined as the initial point of interest end time included in the initial map version information.
[0069] The second sub-step is to determine the difference between the initial point of interest end time and the reference time as the version number difference.
[0070] The third sub-step is to determine the sum of the version number difference and the base version number as the initial point of interest end version number included in the initial map version information.
[0071] The second step is to generate a target point of interest map identifier and target point of interest map data based on the target point of interest information.
[0072] In practice, based on the above target point of interest information, the above execution subject can generate the target point of interest map identifier and the target point of interest map data through the following sub-steps:
[0073] In a first sub-step, the target point of interest identifier included in the target point of interest information is determined as the target point of interest map identifier.
[0074] In a second sub-step, the target interest point data included in the target interest point information is determined as target interest point map data.
[0075] The third step is to generate the target point of interest start time, target point of interest end time, target point of interest start version number and target point of interest end version number based on the above initial map version information.
[0076] In practice, based on the above initial map version information, the above execution subject can generate the target point of interest start time, target point of interest end time, target point of interest start version number and target point of interest end version number through the following sub-steps:
[0077] In the first sub-step, the end time of the initial point of interest included in the initial map version information is determined as the start time of the target point of interest.
[0078] The second sub-step is to determine the current time as the end time of the target point of interest.
[0079] In a third sub-step, the initial point of interest ending version number included in the initial map version information is determined as the target point of interest starting version number.
[0080] The fourth sub-step is to determine the preset end version number as the end version number of the target point of interest. For example, the preset end version number may be 65535.
[0081] Step 4: Combine the target POI map identifier, the target POI map data, the target POI start time, the target POI end time, the target POI start version number and the target POI end version number into target map version information. For example, the target map version information can refer to Figure 4 403 or 405 shown.
[0082] Step 304: Add the target map version information to the map version information sequence corresponding to the preset map version information sequence set.
[0083] In some embodiments, the specific implementation of step 304 and the technical effects brought about can be referred to Figure 2 The corresponding step 204 in the embodiment will not be described in detail here.
[0084] Step 305: In response to receiving the viewing request sent by the user terminal, determining whether the viewing request meets a preset viewing condition.
[0085] In some embodiments, the execution subject may determine whether the viewing request meets a preset viewing condition in response to receiving a viewing request sent by a user terminal. The viewing request may indicate that the user terminal wants to view a map version information of a specified historical version or the latest version. The preset viewing condition may be that the user terminal wants to view a map version information of a specified historical version. For example, the specified historical version may be 2.
[0086] Step 306 , in response to determining that the viewing request satisfies the preset viewing condition, extracting each map version information satisfying the preset extraction condition from the map version information sequence set, and sending each map version information to the user terminal.
[0087] In some embodiments, the execution subject may extract each map version information satisfying the preset extraction condition from the map version information sequence set in response to determining that the viewing request satisfies the preset viewing condition, and may send each map version information to the user terminal. The preset extraction condition may be that the starting version number of the point of interest included in the map version information is less than or equal to the specified historical version, and the ending version number of the point of interest included in the map version information is greater than the specified historical version.
[0088] Optionally, in response to determining that the viewing request does not meet the preset viewing condition, each map version information corresponding to the map version number corresponding to the viewing request is extracted from the map version information sequence set, and each map version information is sent to the user terminal.
[0089] In some embodiments, the execution entity may, in response to determining that the viewing request does not satisfy the preset viewing condition, extract each map version information corresponding to the map version number corresponding to the viewing request from the map version information sequence set, and send the each map version information to the user terminal. The fact that the viewing request does not satisfy the preset viewing condition may indicate that the user terminal wants to view the latest version of the map version information. In practice, first, the execution entity may extract each map version information whose map version information includes a point of interest end version number that is the same as the preset end version number from the map version information sequence set. Then, the execution entity sends the each map version information to the user terminal.
[0090] from Figure 3 It can be seen that Figure 2 Compared with the description of some corresponding embodiments, Figure 3 The process 300 of the map version information generation method in some corresponding embodiments adds another point of interest version number to the map version information in the map version information sequence set. Thus, one of the two point of interest version numbers included in the map version information can be a point of interest start version number, which can represent the version number at which the version of the map corresponding to the map version information starts to take effect, and the other point of interest version number can be a point of interest end version number, which can represent the version number at which the version of the map corresponding to the map version information ends to take effect. Thus, the various map version information that the user terminal wants to view can be extracted based on the specified version number that the user terminal wants to view between the point of interest start version number and the point of interest end version number. When the user terminal wants to view the latest version of map data, the various map version information whose point of interest end version number is the same as the preset end version number can be directly extracted. Therefore, the waste of extraction time can be reduced.
