[0048] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can also be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0049] Figure 1 is a flow chart of a method for updating road network data provided by an embodiment of the present invention. Figure 1 As shown, the road network data updating method comprises:

[0050] Step 101: Obtain road network change intelligence information obtained through various road monitoring methods.

[0051] Here, road conditions are monitored through multiple road monitoring methods, and road network change intelligence information is obtained through the monitoring results of multiple road monitoring methods, thereby integrating multi-path perception to discover road network element changes and form intelligence information, increasing the diversity and comprehensiveness of intelligence access, and improving the accuracy and reliability of perception of road network element changes, avoiding inaccurate perception of a single path method and missing change information.

[0052] Among them, after monitoring the changes of road network elements through multiple road monitoring methods, the monitoring results of the multiple road monitoring methods can be made into intelligence information according to a preset unified format. For example, intelligence information is made in the format of source channel (i.e., which road monitoring method) + monitoring time + road network element type + road network element before change + road network element after change. However, this format is only for illustration, and the embodiment of the present invention does not limit the format of intelligence information, and any reasonable intelligence information format can be applied to the embodiment of the present invention.

[0053] Among them, the road network refers to a road system composed of various roads that are interconnected and interwoven into a network. The road network element types include road type, speed limit information, traffic signal light information, etc.

[0054] Preferably, the above step 101 includes:

[0055] Step 1011: Obtain road network change intelligence information based on road images taken by satellite, terminal-side driving trajectories, road images taken by cameras, and / or road change feedback information reported by the terminal.

[0056] At this time, various road monitoring methods such as road images taken by satellites, terminal-side driving trajectories, open source street view road images taken by cameras, and road change feedback information reported by user terminals are used to explore changes in road network elements and form intelligence information, which increases the diversity and comprehensiveness of intelligence access and improves the accuracy and reliability of the perception of changes in road network elements.

[0057] Among them, the embodiments of the present invention do not limit the method of mining road network elements based on road images, driving trajectories, etc. Any method in the prior art that can realize mining road network elements based on road images, driving trajectories, etc. can be applied to the embodiments of the present invention.

[0058] Of course, the road monitoring methods of the embodiments of the present invention are not limited to the above methods. For example, intelligence information can also be obtained through a third-party map database.

[0059] Step 102: De-duplication processing is performed on the acquired road network change information based on the stored unprocessed road network change intelligence information, and the authenticity of the de-duplication road network change intelligence information is verified.

[0060] Here, after obtaining the road network change intelligence information obtained through various road monitoring methods, the intelligence information is uniformly deduplicated, that is, based on the stored unprocessed road network change intelligence information, the duplicate road network change intelligence information in the obtained road network change information is deduplicated, and the authenticity of the deduplicated road network change intelligence information is verified to avoid repeated and ineffective operations of duplicate and useless intelligence.

[0061] Among them, when verifying the authenticity of the road network change intelligence information after deduplication, cross-verification can be carried out in combination with road monitoring conditions from other sources, open source data from third-party databases, etc., to comprehensively judge the authenticity of this intelligence information.

[0062] Step 103: triggering image acquisition for the designated roads in the target road network change intelligence information that has been verified for authenticity, and extracting road network elements in the acquired images.

[0063] Here, for the target road network change intelligence information that has been verified for authenticity, the image collection of the designated road is triggered, and the road network elements in the image are extracted to further verify the intelligence information to ensure its accuracy and authenticity.

[0064] The embodiment of the present invention does not limit the method for collecting the image of the designated road in the target road network change intelligence information, and any reasonable collection method in the prior art can be applied to the embodiment of the present invention. For example, the target road network change intelligence information can be pushed to a multi-source collection system capable of completing road image collection to complete the image collection of the designated road in the intelligence.

[0065] The embodiment of the present invention does not limit the method for extracting road network elements from the image, and any reasonable extraction method in the prior art can be applied to the embodiment of the present invention. For example, the road network elements in the image can be extracted through image recognition.

[0066] Step 104: Verify the target road network change intelligence information based on the road network elements in the collected image.

[0067] Here, the target road network change intelligence information is checked based on the road network elements in the collected designated road images to ensure its accuracy and authenticity.

[0068] Step 105: When it is verified that the target road network change intelligence information is accurate, the road network database is updated according to the target road network change intelligence information.

[0069] Here, when the target road network change intelligence information is verified to be accurate, the road network database is updated based on the target road network change intelligence information, thereby realizing the automated perception, verification, and update process of road network changes.

[0070] The road network data updating method of the embodiment of the present invention realizes an automated process from sensing road network intelligence to verifying and then updating the road network database, greatly shortening the time cycle of road network data updating, and can achieve an upgrade from monthly updates to daily updates, while avoiding repeated and invalid operations, reducing the burden of manual operations, and through multiple verifications and checks, fully ensuring the accuracy and reliability of updated road network data.

[0071] Preferably, in the above step 102, the step of verifying the authenticity of the road network change intelligence information after deduplication includes:

[0072] Step 1021: Determine the target road monitoring method used by the road network change intelligence information to be verified, and the target designated road in the road network change intelligence information to be verified.

[0073] Here, by analyzing and determining the target road monitoring method used by the road network change intelligence information to be verified, that is, the source channel of the intelligence information and the target designated road in the intelligence information, support is provided for finding relevant information, thereby realizing the verification of the intelligence information.

[0074] Step 1022: Acquire road monitoring data of the target designated road obtained by other road monitoring methods except the target road monitoring method.

[0075] Here, the monitoring data of the target designated road is obtained by other road monitoring methods to cross-verify the road network change intelligence information to be verified.

[0076] Step 1023: Verify the authenticity of the road network change intelligence information to be verified based on the road monitoring data of the target designated road, the historical image data of the target designated road and / or the road network elements of the target designated road obtained through a third-party map database.

[0077] Here, based on the road monitoring data of the target designated road obtained through other road monitoring methods, the historical image data of the target designated road, the road network elements of the target designated road obtained through a third-party map database, etc., the authenticity of the road network change intelligence information to be verified is comprehensively verified, which can remove unreliable intelligence information, ensure the authenticity of the intelligence, avoid ineffective operations on useless intelligence, and improve processing efficiency. Among them, the historical image data of the target designated road can be historical image data obtained through various channels, such as image data collected manually or by the system. The third-party map database can be any open source map database.

[0078] For example, assuming that the road network change intelligence information to be verified is the intelligence information on the road type changes of a certain road generated by mining the terminal-side driving trajectory, the satellite images of the road, the street view images taken by the camera, the historical images of the road, and the road type information about the road in the third-party map database can be comprehensively compared to verify the authenticity of this intelligence information.

[0079] Preferably, the above step 105 includes:

[0080] Step 1051: When the target road network change intelligence information is confirmed to be accurate, the confidence level of the target road network change intelligence information is determined based on the road monitoring method and / or acquisition time used by the target road network change intelligence information.

[0081] Here, when the target road network change intelligence information is checked against the road network elements in the collected designated road image to determine that the intelligence is accurate, the confidence level of the target road network change intelligence information is determined based on the road monitoring method (i.e., its source) and / or the time of acquisition used by the target road network change intelligence information, so as to decide whether to review the intelligence information based on the confidence level.

[0082] Among them, the confidence level of the road network change intelligence information obtained at different times and through different channels is different. For example, for the road network change intelligence information obtained through road images taken by satellite half a year ago, the confidence level is relatively low due to the long time. However, for the road network change intelligence information obtained through road images specially taken by cameras within the past month, the confidence level is relatively high. Generally speaking, the longer the time of acquisition, the lower the confidence level, and the data contributed by a third party has a lower confidence level than the specially collected data. The present invention comprehensively considers the time and source of acquisition of the intelligence information to determine the confidence level of the intelligence.

[0083] Step 1052: Based on the confidence level, determine whether the target road network change intelligence information needs to be reviewed.

[0084] Here, according to the confidence level of the target road network change intelligence information, it can be known whether the intelligence information is credible, thereby deciding whether it needs to be reviewed.

[0085] Preferably, the above step 1052 includes:

[0086] Step 10521: When the confidence level belongs to the preset high confidence level, it is determined that there is no need to review the target road network change intelligence information.

[0087] Here, intelligence information with a relatively high degree of confidence does not need to be reviewed and can be directly updated to the road network database to reduce workload, save resources and improve processing efficiency.

[0088] Step 10522: When the confidence level belongs to the preset low confidence level, it is determined that the target road network change intelligence information needs to be reviewed.

[0089] Here, intelligence information with a relatively low confidence level needs to be reviewed to further confirm whether the intelligence information is accurate in order to fully ensure the accuracy of the intelligence.

[0090] Step 10523: When the confidence level belongs to the preset medium confidence level, determine whether the target road network change intelligence information needs to be reviewed according to the importance level of the target road network change intelligence information.

[0091] Here, when the confidence level of intelligence information is at a medium level, the intelligence information can be reviewed or not. At this time, whether to review it can be determined based on the importance level of the intelligence information.

[0092] Wherein, step 10523 may further include:

[0093] When the confidence level belongs to the preset medium confidence level and the importance level of the target road network change intelligence information is higher than or equal to the preset level, it is determined that the target road network change intelligence information needs to be reviewed; when the confidence level belongs to the preset medium confidence level and the importance level of the target road network change intelligence information is lower than the preset level, it is determined that the target road network change intelligence information does not need to be reviewed.

[0094] At this time, when the confidence level of intelligence information is at a medium level, intelligence information with a relatively high importance level can be reviewed to fully ensure that the important intelligence information is accurate, while intelligence with a relatively low importance level can be not reviewed to save resources and improve processing efficiency.

[0095] Step 1053: When a review is required, the target road network change intelligence information is reviewed, and when the review determines that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0096] Step 1054: When no review is required, the target road network change intelligence information is updated to the road network database.

[0097] At this time, for the intelligence information that needs to be reviewed, after reviewing and confirming that the intelligence is accurate, the intelligence information will be updated to the road network database to fully ensure the accuracy of the intelligence. For the intelligence information that does not need to be reviewed, it can be directly updated to the road network database.

[0098] Preferably, the above step 1053 includes:

[0099] Step 10531: When review is required, the target road network change intelligence information is displayed to trigger manual review, and when a message is received confirming that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0100] At this time, the accuracy of the intelligence can be fully guaranteed by manual review. Of course, the method of reviewing the intelligence information in the embodiment of the present invention is not limited to this, and other methods can be used for review, such as returning to step 104 for checking again.

[0101] Preferably, after the above step 102 verifies the authenticity of the road network change intelligence information after deduplication, the method further includes:

[0102] Step 106: Determine the importance level of the target road network change intelligence information based on the road monitoring method used by the target road network change intelligence information that has been verified for authenticity and the type of road network change in the target road network change intelligence information.

[0103] Here, we can comprehensively evaluate the importance of the intelligence and determine its level of importance based on the road monitoring method used by the intelligence information (i.e. its source channel) and the type of road network changes described by the intelligence information (such as changes in road type, changes in road speed limit information, changes in traffic lights, etc.).

[0104] Different importance levels can be set for different sources and types of intelligence information. For example, a relatively high importance level can be set for traffic light change intelligence information obtained through road images taken by cameras, and a relatively low importance level can be set for road speed limit change intelligence information reported through terminals. The specific importance levels can be set according to the actual situation of the intelligence information.

[0105] Step 107: Determine the processing priority of the target road network change intelligence information and / or the time interval for collecting images of designated roads in the target road network change intelligence information according to the importance level of the target road network change intelligence information.

[0106] Here, the processing priority, image collection time interval, etc. can be determined according to the importance level of the intelligence information. For more important intelligence, strategic inclinations can be made in terms of processing priority, image collection time interval, etc.

[0107] A specific application example of the road network data updating method according to an embodiment of the present invention is described below.

[0108] like Figure 2 As shown, the road network data updating method of the embodiment of the present invention can be implemented based on the intelligence platform, the intelligence platform connects the intelligence access service and the intelligence operation module, and the road network data updating method includes:

[0109] Step 201: The intelligence access service accesses the road network change intelligence information through various road monitoring methods, and uploads the road network change intelligence information to the intelligence platform.

[0110] The road monitoring methods include taking road images by satellite, monitoring the driving trajectory on the terminal side, taking road images by camera and reporting road change feedback information on the terminal.

[0111] Specifically, the changes in road network elements can be discovered based on road images taken by satellites, driving trajectories on the terminal side, road images taken by cameras, and road change feedback information reported by the terminal, and then intelligence information can be generated based on the changes in road network elements.

[0112] Step 202: The intelligence platform deduplicates the acquired road network change information based on the stored unprocessed road network change intelligence information.

[0113] Step 203: Verify the authenticity of the road network change intelligence information after deduplication.

[0114] Specifically, the target road monitoring method used for the road network change intelligence information to be verified, as well as the target designated road in the road network change intelligence information to be verified can be determined, and then the authenticity of the road network change intelligence information to be verified is comprehensively verified based on the road monitoring data of the target designated road obtained through other road monitoring methods, the historical image data of the target designated road, and the road network elements of the target designated road obtained through a third-party map database.

[0115] At this point, the intelligence platform deduplicates the incoming intelligence and verifies the authenticity of the intelligence based on a unified processing flow.

[0116] Step 204: Determine the importance level of the target road network change intelligence information whose authenticity has been verified.

[0117] Specifically, the importance level of the target road network change intelligence information can be determined based on the road monitoring method used by the target road network change intelligence information and the road network change type in the target road network change intelligence information. For more important intelligence, strategic inclinations can be made in terms of processing priority, time interval for image acquisition, etc.

[0118] Step 205: triggering image acquisition for the designated road in the target road network change intelligence information, and extracting road network elements in the acquired image.

[0119] Specifically, the target road network change intelligence information can be pushed to a crowd-source collection system that can complete road image collection, complete the image collection of the specified roads in the intelligence, and extract the road network elements of the corresponding roads through image recognition technology.

[0120] Step 206: The intelligence platform distributes and pushes the target road network change intelligence information to the intelligence operation module.

[0121] Step 207: The intelligence operation module verifies the target road network change intelligence information based on the road network elements in the collected images.

[0122] Step 208: When the target road network change intelligence information is confirmed to be accurate, the confidence level of the target road network change intelligence information is determined.

[0123] Specifically, the confidence level of the target road network change intelligence information can be determined based on the road monitoring method used and the time when the target road network change intelligence information is obtained.

[0124] Step 209: When the confidence level is a preset high confidence level, it is determined that there is no need to review the target road network change intelligence information, and the target road network change intelligence information is updated to the road network database.

[0125] Step 2010: When the confidence level is a preset low confidence level, it is determined that the target road network change intelligence information needs to be reviewed. When the review determines that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0126] Specifically, the target road network change intelligence information can be displayed to trigger manual review, and when a message is received confirming that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0127] Step 2011: When the confidence level belongs to the preset medium confidence level, and the importance level of the target road network change intelligence information is higher than or equal to the preset level, it is determined that the target road network change intelligence information needs to be reviewed. When the review determines that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0128] Specifically, the target road network change intelligence information can be displayed to trigger manual review, and when a message is received confirming that the target road network change intelligence information is accurate, the target road network change intelligence information is updated to the road network database.

[0129] Step 2012: When the confidence level belongs to the preset medium confidence level and the importance level of the target road network change intelligence information is lower than the preset level, it is determined that there is no need to review the target road network change intelligence information, and the target road network change intelligence information is updated to the road network database.

[0130] The road network data updating method of the embodiment of the present invention detects changes in road network elements through multi-channel fusion perception in a shorter time period, forms intelligence information, and deduplicates and cross-validates the intelligence in a unified manner. It also automatically generates collection tasks based on the intelligence information to complete the collection of changed road network image data. The collection results will extract the changed road network elements, and check and review the intelligence information. Finally, the update of the road network data is completed. The automated perception, verification, and update process of road network changes is realized.

[0131] The road network data updating method of the embodiment of the present invention realizes an automated process from sensing road network intelligence to verifying and then updating the road network database, greatly shortening the time cycle of road network data updating, and can achieve an upgrade from monthly updates to daily updates, while avoiding repeated and invalid operations, reducing the burden of manual operations, and through multiple verifications and checks, fully ensuring the accuracy and reliability of updated road network data.
