[0029] 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 assist in understanding, which should be considered in a descriptive sense only. Thus, it will be apparent to one of ordinary skill in the art 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, for the sake of brevity and clarity, descriptions of well-known functions and constructions are omitted from the following description.

[0030] Applicants found in the development process that the current mainstream map update operation mode is: the server sends the map update information of the target trajectory point and the index information of the target trajectory point to the local client, and the binding relationship between the map update information and the index information is recorded in the sent file. When the operation personnel select the map update information, the target trajectory image of the target trajectory point is automatically opened based on the corresponding index information. The operation personnel performs map update based on the target trajectory image.

[0031] However, the disadvantage of this operation mode is that if the operation personnel operates the same target trajectory point multiple times, the server will repeatedly send the index information of the target trajectory point, resulting in redundant sending of the index information, increasing the data volume of the server sending data, and increasing the pressure on the server. In addition, the server also occupies additional bandwidth and machine resources.

[0032] Figure 1 is a flowchart of some image processing method disclosed according to an embodiment of the present disclosure. The present embodiment can be applied to the case of determining the target trajectory image of the target trajectory point in the map update process. The present embodiment method can be executed by the image processing apparatus disclosed in an embodiment of the present disclosure. The apparatus can be implemented by software and / or hardware, and can be integrated on any electronic device with computing capability.

[0033] As shown in Figure 1 the image processing method disclosed in the present embodiment can include:

[0034] S101, obtaining map update information of a target trajectory point from a server; the map update information includes a target trajectory point identifier of the target trajectory point.

[0035] The service end represents a service server of map updating. The target track point represents a track point associated with the present map updating, and the track point is a collection point of image collection performed once outside the map, and corresponds to at least one collection image and one collection position, that is, a track point image and a track point position. The map updating information represents data for guiding a work personnel to update map data based on a specific map element, and is generated in a program recognition or manual recording manner. In the embodiment, the map updating information includes a map element to be updated and a target track point identifier of the associated target track point. The target track point identifier represents identification information capable of uniquely representing the target track point.

[0036] In an implementation, when the target track point needs to be updated, the service end determines the map element to be updated by the target track point in a program recognition or manual recording manner, for example, recognizes the map element included in the target track point corresponding target track image by a target detection method, for example, frames the map element included in the target track image by a manual framing manner, and the like. The service end further generates the map updating information of the target track point according to the map element to be updated by the target track point and the target track point identifier of the target track point. The service end sends the map updating information to the local client based on a preset communication protocol and address information. The information format of the map updating information includes but is not limited to an exto format.

[0037] The local client obtains the map updating information of the target track point from the service end, and displays the map updating information in a list manner, where the number of target track points can be one or multiple. The work personnel selects any map updating information to work, that is, when the number of target track points is one, the work personnel selects the map updating information of the target track point to work, and when the number of target track points is multiple, the work personnel selects the map updating information of one target track point from the target track points to work.

[0038] Obtaining the map updating information of the target track point from the service end lays a foundation for subsequently determining the cache state of the target index information in the local client.

[0039] S102, determining a cache state of target index information in a local client according to the map updating information; the target index information includes the target track point identifier.

[0040] The target index information indicates index information of a target trajectory image corresponding to the target trajectory point, and the target trajectory image can be obtained through a URL (Uniform Resource Locator) address in the target index information. In addition to the URL address of the target trajectory image, the target index information also includes a target trajectory point identifier of the target trajectory point. The information format of the index information includes, but is not limited to, an exto format.

[0041] In this embodiment, the local client locally caches the index information after obtaining the index information of any trajectory image from the server, so as to realize reuse of the index information, and the server does not need to issue the index information together with the map update information each time.

[0042] In an implementation, the local client parses the map update information to obtain a target trajectory point identifier of a target trajectory point included in the map update information. The target trajectory point identifier is matched with the cached index information in the local client to determine whether the local client has cached target index information corresponding to the target trajectory point.

[0043] If any cached index information of the local client includes the target trajectory point identifier, it is determined that the cache state of the target index information in the local client is a cached state. That is, the target index information of the target trajectory point has been cached in the local client.

[0044] If all cached index information of the local client does not include the target trajectory point identifier, it is determined that the cache state of the target index information in the local client is an uncached state. That is, the target index information of the target trajectory point has not been cached in the local client.

[0045] By determining the cache state of the target index information in the local client according to the map update information, the effect of determining whether the local client has cached the target index information is realized, which lays a foundation for subsequently obtaining the target index information according to the cache state.

[0046] S103, obtaining the target index information according to the cache state of the target index information, and determining a target trajectory image of the target trajectory point according to the obtained target index information.

[0047] The target trajectory image is a collection image corresponding to the target trajectory point.

[0048] In an implementation, if the local client determines that the cache state of the target index information is a cached state, the local client obtains the target index information from the local client, obtains a URL address of the target trajectory image of the target trajectory point from the target index information, and then determines the target trajectory image of the target trajectory point from the Internet based on the URL address.

[0049] In another implementation, the local client determines that the cache state of the target index information is the uncached state, obtains the target index information from the server, and caches the target index information in the local client. The URL address of the target trajectory image of the target trajectory point is obtained from the target index information, and then the target trajectory image of the target trajectory point is determined from the Internet based on the URL address.

[0050] After the target trajectory image of the target trajectory point is determined, the local client renders the target trajectory image to display the target trajectory image, and the worker performs map data updating based on the displayed target trajectory image.

[0051] The disclosure obtains the map updating information of the target trajectory point from the server, determines the cache state of the target index information in the local client according to the map updating information, and then obtains the target index information according to the cache state of the target index information, and determines the target trajectory image of the target trajectory point according to the obtained target index information. Due to the cache operation of the local client on the index information, the effect of local reuse of cached information is achieved, the server only needs to issue map updating information, and does not need to bind and issue index information and map updating information every time, thereby reducing the data amount of data issued by the server, reducing the pressure of the server, and avoiding the occupation of additional bandwidth of the server.

[0052] Figure 2A The flowchart of another image processing method disclosed according to an embodiment of the disclosure is disclosed, which is further optimized and expanded based on the above technical solution, and can be combined with each of the above optional embodiments.

[0053] As shown in Figure 2A The image processing method disclosed in the embodiment can include:

[0054] S201, obtaining map updating information of a target trajectory point from a server; the map updating information includes a target trajectory point identifier of the target trajectory point.

[0055] S2021, in the case that the index information cached in the local client includes the target trajectory point identifier, determining that the cache state of the target index information in the local client is the cached state, and performing S2031.

[0056] In an implementation, the local client matches the target trajectory point identifier with each cached index information, determines whether any cached index information includes the target trajectory point identifier, and if yes, determines that the cache state of the target index information in the local client is the cached state.

[0057] Optionally, the target track point identifier includes position information and number information of the target track point. Correspondingly, the index information cached by the local client includes the position information and the number information of the track point.

[0058] For example, assuming that the position information of the target track point is (X, Y, Z), the position information (X, Y, Z) is matched with the position information of the track point in each of the cached index information. If any of the cached index information includes the position information (X, Y, Z), it is determined that the cache state of the target index information in the local client is the cached state.

[0059] By setting the target track point identifier to include the position information and the number information of the target track point, the richness of the target track point identifier is ensured, and the diversity of the subsequent target track point identifier matching means is increased.

[0060] S2022, in the case where the index information cached by the local client does not include the target track point identifier, it is determined that the cache state of the target index information in the local client is the uncached state, and S2032 is executed.

[0061] In an embodiment, the local client matches the target track point identifier with each of the cached index information, and determines whether any of the cached index information includes the target track point identifier. If not, it is determined that the cache state of the target index information in the local client is the uncached state.

[0062] For example, assuming that the position information of the target track point is (X, Y, Z), the position information (X, Y, Z) is matched with the position information of the track point in each of the cached index information. If all of the cached index information does not include the position information (X, Y, Z), it is determined that the cache state of the target index information in the local client is the uncached state.

[0063] S2031, in the case where the cache state is the cached state, the index information matched with the target track point identifier is obtained from the local client as the target index information.

[0064] In an embodiment, the local client caches the index information matched with the target track point identifier as the target index information.

[0065] For example, assuming that the position information of the target track point is (X, Y, Z), the position information (X, Y, Z) is matched with the position information of the track point in each of the cached index information. If the index information A includes the position information (X, Y, Z), the index information A is taken as the target index information.

[0066] S2032, in the case that the cache state is the uncached state, obtaining, from the server, index information matching the target trajectory point identifier as target index information, and caching the target index information in the local client.

[0067] In an embodiment, the local client generates an index information request according to the target trajectory point identifier, and sends the index information request carrying the target trajectory point identifier to the server, so that the server feeds back target index information matching the target trajectory point identifier to the local client.

[0068] Illustratively, assuming that the position information of the target trajectory point is (X, Y, Z), the position information (X, Y, Z) is matched with the position information of the trajectory point in each cached index information, if all cached index information does not include the position information (X, Y, Z), the index information request carrying the position information (X, Y, Z) is sent to the server, and the server feeds back index information matching the position information (X, Y, Z) as target index information to the local client.

[0069] S204, determining a target trajectory image of the target trajectory point according to the obtained target index information, and displaying the target trajectory image of the target trajectory point as map update guide information of the target trajectory point.

[0070] In an embodiment, the local client obtains a URL address of the target trajectory image of the target trajectory point from the target index information, and then determines the target trajectory image of the target trajectory point from the Internet based on the URL address. The local client renders the target trajectory image to display the target trajectory image, and the operator takes the target trajectory image as map update guide information, and then updates the map data associated with the target trajectory point.

[0071] This disclosure determines the cached state of the target index information on the local client as cached when the cached index information includes the target trajectory point identifier, and as uncached when the cached index information does not include the target trajectory point identifier. This achieves the effect of determining the cached state of the target index information on the local client based on the target trajectory point identifier, laying the foundation for subsequently using different technical means to obtain the target index information based on different cached states. Furthermore, by retrieving the index information matching the target trajectory point identifier from the local client when the cached state is cached, it serves as the target index information. The system identifies and indexes information, enabling local reuse of cached information and reducing the amount of data sent from the server. When the cache is not cached, it retrieves index information matching the target trajectory point identifier from the server as the target index information and caches it on the local client. This achieves the effect of retrieving and caching target index information from the server, laying the foundation for subsequent reuse of the target index information on the local client. By displaying the target trajectory image of the target trajectory point as map update guidance information, it assists operators in updating map data through the target trajectory image, ensuring the accuracy of map data updates.

[0072] Figure 2B These are schematic diagrams illustrating target trajectory images disclosed in embodiments of this disclosure, such as... Figure 2B As shown, 20 represents the target trajectory point. After the target trajectory image 21 of the target trajectory point 20 is determined, the target trajectory image 21 is displayed and used as map update guidance information for the target trajectory point 20.

[0073] During the research and development process, the applicant also discovered that in the current mainstream map update operation mode, since the server only distributes the index information of the target trajectory point and the map update information in a unified manner, the trajectory point images that the operators can refer to are fixed and limited in number. That is, there are only target trajectory images corresponding to the target trajectory points. This results in too little image information for operators to refer to in road situations such as complex intersections, which may lead to the omission of some special map elements, resulting in low quality of map update results, or even the inability to update the map.

[0074] Figure 3A This is a flowchart of some other image processing methods disclosed in the embodiments of this disclosure, which are further optimized and extended based on the above technical solutions, and can be combined with the above optional implementation methods.

[0075] like Figure 3A As shown, the image processing method disclosed in this embodiment may include:

[0076] S301. Obtain map update information of the target trajectory point from the server; the map update information includes the target trajectory point identifier of the target trajectory point.

[0077] S302. In response to the selection operation of other trajectory points in the target area where the target trajectory point is located, other trajectory point identifiers are determined.

[0078] In one implementation, the local client displays a target area centered on the target trajectory point based on the target trajectory point identifier in the map update information. Within this target area, there are other trajectory points besides the target trajectory point. Operators can select other trajectory points within the target area according to their actual needs, and the local client responds to the selection operation by identifying the identifiers of these other trajectory points.

[0079] Optionally, other trajectory point identifiers include the location information and number information of other trajectory points.

[0080] By setting other trajectory point identifiers, including their location and number information, the richness of other trajectory point identifiers is ensured, and the diversity of subsequent methods for matching other trajectory point identifiers is increased.

[0081] S303. Determine the cache status of other index information in the local client; the other index information includes the identifiers of the other trajectory points.

[0082] The "Other Index Information" section represents the index information of other trajectory points corresponding to other trajectory images. These other trajectory images can be obtained through the URL addresses in the Other Index Information. Besides the URL addresses of the other trajectory images, the Other Index Information also includes the identifiers of the other trajectory points. The information format of the index information includes, but is not limited to, the exto format.

[0083] In one implementation, if the index information cached on the local client includes other trajectory point identifiers, the cached state of the other index information on the local client is determined to be cached.

[0084] In another implementation, if the index information cached on the local client does not include other trajectory point identifiers, the cached state of other index information on the local client is determined to be uncached.

[0085] S304. Based on the cache status of the other index information, obtain the other index information, and based on the obtained other index information, determine the other trajectory images of the other trajectory points.

[0086] In one implementation, if the cached state of other index information in the local client is cached, the index information that matches the identifier of other trajectory points is obtained from the local client as other index information, and the URL address of other trajectory images of other trajectory points is obtained from the other index information, and then other trajectory images of other trajectory points are determined from the Internet based on the URL address.

[0087] In another implementation, if the cached state of other index information in the local client is not cached, the index information that matches the identifier of other trajectory points is obtained from the server as other index information, and the other index information is cached in the local client. The URL address of other trajectory images of other trajectory points is obtained from the other index information, and then other trajectory images of other trajectory points are determined from the Internet based on the URL address.

[0088] S305. Display other trajectory images of the other trajectory points as map update guidance information for the target trajectory point.

[0089] In one implementation, the local client renders other trajectory images to display other trajectory images, and the operators use these other trajectory images as map update guidance information to update the map data associated with the target trajectory point.

[0090] For example, if the target trajectory point is a certain intersection, and the other trajectory points are another intersection adjacent to that intersection, the local client will display the target trajectory image of the target trajectory point, as well as the other trajectory images of the other trajectory points, to assist the operators in updating the map data associated with the target trajectory point.

[0091] This disclosure obtains map update information of the target trajectory point from the server, responds to the selection operation of other trajectory points in the target area where the target trajectory point is located, determines the other trajectory point identifiers of other trajectory points, determines the cache status of other index information in the local client, obtains other index information based on the cache status of other index information, and determines other trajectory images of other trajectory points based on the obtained other index information, and displays other trajectory images of other trajectory points as map update guidance information for the target trajectory point. This achieves the effect of enriching the image information that operators can refer to, enabling operators to update the map data associated with the target trajectory point based on the target trajectory image and other trajectory images simultaneously, improving the quality of map data update results, and avoiding the problem that map data updates may not be possible based solely on the target trajectory image.

[0092] Based on the above embodiments, it also includes:

[0093] Based on the number of indexes and the number threshold of index information cached in the local client, the index information is deleted according to the caching time.

[0094] In one implementation, when the number of indexes cached in the local client exceeds a threshold, the local client initiates an eviction mechanism to evict the last indexes. That is, the number of indexes to be deleted is determined based on the number of indexes and the threshold, and the indexes with earlier cache times are deleted according to the number of indexes to be deleted.

[0095] For example, assuming the quantity threshold is 100 and the number of indexes is 105, the number of indexes to be deleted is determined to be 5. Then, the index information is sorted according to the cache time, and the 5 index information with the earliest cache time is deleted.

[0096] By deleting index information based on the number of indexes and the number threshold in the local client's cached index information according to the cache time, the problem of excessive disk space usage on the local client is avoided, thus ensuring the system performance of the local client.

[0097] Optionally, this embodiment also provides another implementation method for displaying other trajectory images of other trajectory points, including:

[0098] 1) Obtain map update information of the target trajectory point from the server; the map update information includes the target trajectory point identifier.

[0099] 2) Identify the other trajectory points in the target area where the target trajectory point is located, excluding the target trajectory point.

[0100] In one implementation, the local client displays the target area centered on the target trajectory point based on the target trajectory point identifier in the map update information. The local client also determines the other trajectory point identifiers for each trajectory point other than the target trajectory point.

[0101] Figure 3B This is a schematic diagram of some target areas disclosed in the embodiments of this disclosure, such as... Figure 3B As shown, 30 represents the area to be worked on, i.e., the entire map area, and 31 represents the target area where the target trajectory point is located. Then, the other trajectory point identifiers of other trajectory points in the target area 31, excluding the target trajectory point, are determined.

[0102] 3) Determine the cache status of other index information in the local client; other index information includes other trajectory point identifiers.

[0103] In one implementation, the identifiers of other trajectory points are matched with the index information cached in the local client to determine the cache status of the other index information of other trajectory points in the local client.

[0104] 4) Based on the cache status of other index information, obtain other index information, and based on the obtained other index information, determine other trajectory images of other trajectory points.

[0105] In one implementation, if the cached state of other index information of any other trajectory point is cached, the index information matching the other trajectory point identifier of the other trajectory point is obtained from the local client as the other index information of the other trajectory point, and then the other trajectory image of the other trajectory point is determined from the Internet based on the URL address in the other index information.

[0106] In one implementation, if the cached state of other index information of any other trajectory point is uncached, the index information matching the other trajectory point identifier of the other trajectory point is obtained from the server as the other index information of the other trajectory point, and the other index information is cached in the local client, and then the other trajectory images of the other trajectory point are determined from the Internet based on the URL address in the other index information.

[0107] 5) In response to the selection operation of any other trajectory point, display other trajectory images of other trajectory points, which are used as map update guidance information for the target trajectory point.

[0108] In one implementation, the local client deserializes the other index information of each other trajectory point and renders and displays each other trajectory point in the target area. The user selects any other trajectory point according to actual needs, and the local client accordingly renders the other trajectory images of that other trajectory point to display as map update guidance information for the target trajectory point.

[0109] This implementation obtains other index information of all other trajectory points in the target area by default, and then determines other trajectory images of each other trajectory point. This allows the local client to directly render and display the image when the operator selects any other trajectory point, reducing user waiting time and improving map update efficiency.

[0110] Optionally, users can also drag the target area to change the current display area of ​​the local client, that is, change the current display area from the target area to the auxiliary area.

[0111] Further, the auxiliary trajectory point identifiers of the auxiliary trajectory points included in the auxiliary area are determined. The cache state of the auxiliary index information in the local client is determined; the auxiliary index information includes the auxiliary trajectory point identifiers. Based on the cache state of the auxiliary index information, the auxiliary index information is obtained, and based on the obtained auxiliary index information, the auxiliary trajectory image of the auxiliary trajectory point is determined. In response to the selection operation of any auxiliary trajectory point, the auxiliary trajectory image of the auxiliary trajectory point is displayed, which is used as map update guidance information for the target trajectory point.

[0112] Figure 3C This is a schematic diagram of some auxiliary areas disclosed in the embodiments of this disclosure, such as... Figure 3C As shown, 30 represents the area to be worked on, i.e., the entire map area, and 31 represents the target area where the target trajectory point is located. When the operator drags the target area 31 to change it to the auxiliary area 32, the auxiliary trajectory image of the auxiliary trajectory point selected by the user in the auxiliary area 32 is determined and displayed.

[0113] By displaying auxiliary trajectory images of auxiliary trajectory points in the auxiliary area, the image information available to operators is greatly enriched. This allows operators to update the map data associated with the target trajectory points simultaneously based on the target trajectory image, other trajectory images, and auxiliary trajectory images, further improving the quality of map data update results and avoiding the problem that map data updates may not be possible based solely on the target trajectory image.

[0114] Figure 4 This is a schematic diagram of the structure of some image processing apparatuses disclosed in embodiments of this disclosure, which can be applied to the situation of determining the target trajectory image of target trajectory points during map updating. The apparatus of this embodiment can be implemented in software and / or hardware and can be integrated into any electronic device with computing capabilities.

[0115] like Figure 4 As shown, the image processing apparatus 40 disclosed in this embodiment may include an information acquisition module 41, a cache state determination module 42, and an image determination module 43, wherein:

[0116] Information acquisition module 41 is used to acquire map update information of target trajectory points from the server; the map update information includes the target trajectory point identifier of the target trajectory point;

[0117] The cache status determination module 42 is used to determine the cache status of the target index information in the local client based on the map update information; the target index information includes the target trajectory point identifier.

[0118] The image determination module 43 is used to obtain the target index information according to the cache state of the target index information, and determine the target trajectory image of the target trajectory point according to the obtained target index information.

[0119] Optionally, the cache state determination module 42 is specifically used for:

[0120] If the index information cached on the local client includes the target trajectory point identifier, the cached state is determined to be cached.

[0121] If the index information cached on the local client does not include the target trajectory point identifier, the cache status is determined to be an uncached state.

[0122] Optionally, the image determination module 43 is specifically used for:

[0123] If the cached state is cached, the index information matching the target trajectory point identifier is obtained from the local client and used as the target index information.
