Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the present invention, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features.

In the prior art, when inspecting high-precision map data, the data to be inspected is not distinguished, and all data are inspected one by one using preset inspection rules. This inspection method in the prior art has redundant inspection, that is, data that does not need to be inspected will also be inspected, which takes up inspection time and results in low data inspection efficiency.

Based on the above technical problems, the present invention provides a method and device for checking high-precision map data. Before the data inspection, the data objects contained in the data to be inspected are divided into two types by labeling, one is the data object with the update label, and the other is the data object without the update label. Further, corresponding inspection rules are respectively executed for the above two different data objects, which avoids redundant inspection existing in the prior art and improves the efficiency of data inspection.

The technical solutions of the present invention and how the technical solutions of the present application solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of Embodiment 1 of a method for checking high-precision map data provided by the present invention. As shown in Figure 1, the method for checking high-precision map data provided by this embodiment includes:

S101, according to the update information of each data object in the data to be checked, add an update label to the data label of the data object that has been updated in the data to be checked, and the data label of the data object that has not been updated defaults to an unupdated label .

Specifically, first, according to the update information of each data object in the data to be checked, the data objects contained in the data to be checked are divided into "data objects that have been updated" and "data objects that have not been updated"; The data tag of the data object that has been updated plus the update tag.

It should be noted that: the data label of "unupdated data object" is not processed, and the label is not updated by default.

The update label described above needs to be maintained, that is, after the data to be checked is checked, the data needs to be batch processed to remove the update label before a new version operation starts for the data.

Specifically, the data objects contained in the data to be checked are divided into: node Node and connecting line Link. The update information of the data object represents the update information of Node or the update information of Link.

Wherein, the tagging according to the update information of the data object can be implemented as follows: according to the update information of the geometric position and attribute information of each data object in the data to be checked, the data of the data object that has been updated in the data to be checked tag plus update tag.

The following is an example of how to label the data object when the data object is Node and Link:

In the first case, the data object is Node.

Referring to Figure 2, it is assumed that the connecting line entering the Node is LinkA, and the connecting line exiting the Node is LinkB, respectively. Update information, update information of LinkB geometric position, update information of LinkB attribute information. Assuming that, as shown in Figure 3, the obtained geometric positions and attribute information of Node, LinkA and LinkB have not changed, which means that the above Node has not been updated, and no processing is performed on the data label of the above Node, that is, the above Node is directly defaulted. The data label of is not updated label.

Correspondingly, if the geometric position or attribute information of any one of Node, LinkA, or LinkB in FIG. 3 changes, an update label is added to the data label of the above-mentioned Node.

It should be noted that there may be multiple connecting lines entering the above Node and connecting lines exiting the above Node. In this case, the same processing as the above LinkA and LinkB is performed for all incoming Links and all exiting Links.

In the second case, the data object is Link.

Referring to FIG. 4 , it is assumed that the node entering the Link is NodeA, the node exiting the Link is NodeB, the connecting line entering the above Link is LinkA, and the connecting line exiting the above Link is LinkB. The update information of the geometric positions and the update information of the attribute information of the above-mentioned Link, NodeA, NodeB, LinkA, and LinkB are obtained respectively. Assuming that, as shown in Figure 5, the obtained geometric positions and attribute information of Link, NodeA, NodeB, LinkA, and LinkB have not changed, it means that the above-mentioned Link has not been updated, and no processing is performed on the data label of the above-mentioned Link, that is, directly By default, the data label of the above Link is the unupdated label.

Correspondingly, if the geometric position or attribute information of any one of Link, NodeA, NodeB, LinkA, and LinkB in FIG. 5 changes, an update label is added to the data label of the above-mentioned Link.

It should be noted that there may be multiple nodes entering the above Link, nodes exiting the above Link, connecting lines entering the above Link, and connecting lines exiting the above Link. The nodes do the same processing as the nodes shown in Figure 5. Treat all incoming and outgoing connections the same way as the connections shown in Figure 5.

In the following, in the above two cases, how to obtain the update information of the geometric position and the update information of the attribute information in Fig. 3 and Fig. 5 can be described:

Referring to Fig. 6, the achievable way to obtain the update information of Node's geometric position is: assuming that the coordinates of Node change as (x1, y1, z1)→(x2, y2, z2), if any of x, y, z If the value changes, the update information of the node's geometric position is determined as: change.

An implementation manner of acquiring the update information of the Node attribute information is: if the value of any attribute field of the Node increases, decreases or changes, it is determined that the update information of the Node attribute information is: change.

The achievable way to obtain the update information of the geometric position of the Link is to obtain the coordinate changes of the starting endpoint and the shape point of the Link. If the coordinates of any one of the starting endpoint and the shape point change, the update information of the geometric position of the Link is determined as: Variety.

The achievable way of acquiring the update information of the attribute information of the link is: if the value of any attribute field of the link increases, decreases or changes, it is determined that the update information of the attribute information of the link is: change.

S102: Execute a first check rule on a data object whose data label is an update label in the data to be checked, to obtain a first check result.

S103: Execute a second check rule on the data object whose data label is an unupdated label in the data to be checked, to obtain a second check result.

S104. Store the first inspection result and the second inspection result.

Specifically, the first check rule performed on the data object whose data label is the update label in S102 includes the second check rule performed on the data object whose data label is the unupdated label in S103, that is, in the process of data checking , not all data objects perform the same inspection, and the inspection process is removed in the present invention for data objects that do not need to be inspected. The redundant checking existing in the prior art is avoided, and the efficiency of data checking is improved.

In the high-precision map data inspection method provided by this embodiment, before data inspection, according to the update information of each data object in the data to be inspected, a data label is applied to each data object in the data to be inspected, and then a data label is applied to the data to be inspected. In the data to be checked, the data object whose data label is an updated label executes the first check rule, and the data object in the data to be checked whose data label is an unupdated label executes the second check rule. Redundant checking improves the efficiency of data checking.

The implementation manner of checking data objects that have not been updated will be described in detail below with reference to specific embodiments.

FIG. 7 is a schematic flowchart of Embodiment 2 of the method for checking high-precision map data provided by the present invention. As shown in FIG. 7 , the method for checking high-precision map data provided by this embodiment includes:

S701. According to the update information of each data object in the data to be checked, add an update label to the data label of the updated data object in the data to be checked, and the data label of the data object that has not been updated is an unupdated label by default.

The achievable manner of S701 may refer to the foregoing embodiments, and details are not described herein again in the present invention.

S702: Execute a first check rule on the data object whose data label is an update label in the data to be checked, to obtain a first check result.

Wherein, the first inspection rules include: local inspection rules and global inspection rules.

The difference between the local inspection rules and the global inspection rules is that the inspection reference information is different. See Figure 8:

1) If the inspection object of the inspection rule is Node, then when the inspection reference information is the inspection Node, entering the link, and exiting the Link, the inspection rule is a "local inspection rule".

2) If the inspection object of the inspection rule is Link, when the inspection reference information is the inspection Link, the starting node, the ending node, the entry link, and the exit link, the inspection rule is a "local inspection rule".

3) Except for 1) and 2), other inspection rules are "global inspection rules".

S703. According to the version number of the local inspection rule, determine whether the version number of the local inspection rule is consistent with the version number of the local inspection rule used in the last local inspection of the data object whose data label is an unupdated label.

S704. If they are consistent, execute the global check rule on the data object whose data label is an unupdated label in the data to be checked.

Specifically, if the version number of the local inspection rules used in this inspection is the same as the version number of the local inspection rules used in the last local inspection, that is, the local inspection rules used in this inspection are the same as the local inspection rules used in the last local inspection. If the rules are consistent, the global check rules are executed for the data objects whose data labels are not updated labels.

It can be seen that, in the above case, for the data object whose data label is the update label, the local check rules and the global check rules are executed. The global check rule to execute for data objects whose data labels are not updated labels. That is to say, there is no need to perform partial checking for data objects whose data labels are not updated labels, which improves the efficiency of data checking.

For example: as shown in FIG. 9 and FIG. 10 , it is assumed that 70% of the first check rules executed on the data object whose data label is the update label in S702 are “local check rules” and 30% are “global check rules” , the data object whose data label is the update label accounts for 10% of the data to be checked. Assuming that each check takes the same time, it can be estimated:

The time-consuming of prior art inspection is: 1 (all data)*100%=1

The inspection time in this embodiment is: 0.1 (updated data)*70%+1 (all data)*30%=0.37

It can be seen from the above that the inspection time in this embodiment is reduced to 37% of the prior art, and the efficiency is increased by about 3 times.

S705. Store the first check result, the second check result, the identification information and version number of the local check rule and the global check rule.

Since, in the process of data inspection, it is necessary to compare the version numbers of the local inspection rules. Therefore, while storing the data inspection results, the identification information and version numbers of the local inspection rules and global inspection rules executed this time can also be stored. .

The identification information may include: an inspection rule number and a rule identifier, where the inspection rule number may also be called an inspection rule ID, which is used to uniquely identify an inspection rule. Rule IDs are used to differentiate between "local checks" and "global checks".

Specifically, the identification information and version number of each local check rule and each global check rule may be stored in the manner shown in FIG. 11 .

Optionally, the version number of the local inspection rule may be recorded in the data tag of the data object whose tag has not been updated.

The method for checking high-precision map data provided in this embodiment describes in detail an implementation way to check unupdated data. The checking method in this embodiment can reduce the time consuming of checking, and greatly improve the efficiency of data checking. .

FIG. 12 is a schematic flowchart of Embodiment 3 of the method for checking high-precision map data provided by the present invention. As shown in FIG. 12 , the method for checking high-precision map data provided by this embodiment includes:

S1201. According to the update information of each data object in the data to be checked, add an update label to the data label of the updated data object in the data to be checked, and the data label of the unupdated data object is an unupdated label by default.

S1202: Execute a first check rule on the data object whose data label is an update label in the data to be checked, to obtain a first check result.

S1203. According to the version number of the local inspection rule, determine whether the version number of the local inspection rule is consistent with the version number of the local inspection rule used in the last local inspection of the data object whose data label is an unupdated label.

For the implementation manner of S1201-S1203, reference may be made to the above-mentioned embodiments S701-S703, and details are not described herein again in the present invention.

S1204. If inconsistent, execute the local check rule and the global check rule on the data object whose data label is an unupdated label in the data to be checked.

Specifically, if the version number of the local inspection rule used in this inspection is inconsistent with the version number of the local inspection rule used in the last local inspection, that is, the local inspection rule used in this inspection is the same as the one used in the last local inspection. If the rules are inconsistent, the local check rules and the global check rules are executed for the data objects whose data labels are unupdated labels.

It can be seen that, in the above case, for the data object whose data label is the update label, the local check rules and the global check rules are executed. For data objects whose data labels are not updated labels, local check rules and global check rules are also executed.

Because the unupdated data and the updated data are topologically connected and have a linkage effect on each other, after the inspection rules are optimized and upgraded, if the unupdated data is not checked, the linkage error of the unupdated data cannot be detected. In the data inspection method provided by this embodiment, when it is judged that the local inspection rule used in the second inspection is inconsistent with the local inspection rule used in the previous local inspection, the data object whose data label is an unupdated label is compared with the data label as an updated label. The data objects are processed in the same way, thus avoiding the missed checking of linkage errors in the unupdated data after the checking rules are upgraded and optimized.

S1205. Store the first check result, the second check result, the identification information and version number of the local check rule and the global check rule.

Wherein, for the implementable manner of S1205, refer to S705 in the foregoing embodiment, and details are not described herein again in the present invention.

The method for checking high-precision map data provided in this embodiment describes in detail another possible way to check unupdated data. The checking method in this embodiment avoids checking the unupdated data after upgrading and optimizing the checking rules. Missing check of linkage errors.
