Description

Technical Field

[0002] High-precision maps, also known as high-accuracy maps, are used by self-driving cars. They contain precise vehicle location information and rich road element data, helping cars predict complex road conditions such as slope, curvature, and heading, helping them better avoid potential risks. Map production, especially for high-precision maps, is typically performed in parallel across multiple regions, shortening production cycles. Because map data between regions is inevitably interconnected, map data from different tasks must be linked, or edge-connected.

[0033] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0034] First embodiment

[0035] like Figure 1 As shown, the present disclosure provides a method for producing a high-precision map, which is applied to a first electronic device and includes the following steps:

[0036] Step S101: During the process of producing map data for the first task in the scheduled map annotation task, if a data interaction instruction of the first map data in the first task is monitored, a permission application request is sent to the second electronic device based on the data interaction instruction, wherein the data interaction instruction indicates that there is data interaction between the first map data and the second task in the map annotation task, and the permission application request is used to request the first task to have writable permission for the second map data, where the second map data is the map data in the second task that has data interaction with the first map data.

[0037] In this embodiment, the high-precision map production method relates to the field of data processing technology, particularly the field of high-precision map technology, and can be widely applied in high-precision map production and update scenarios. The high-precision map production method of the disclosed embodiment can be executed by the high-precision map production device of the disclosed embodiment. The high-precision map production device of the disclosed embodiment can be configured in a first electronic device to execute the high-precision map production method of the disclosed embodiment.

[0038] The first electronic device may be an electronic device that schedules the first task in the map annotation task, i.e., the first electronic device generates data for map elements (such as roads, grasslands, buildings, etc.) by scheduling the first task. The first electronic device scheduling the first task to generate data for map elements means scheduling the first task to edit the map data of the map elements, such as adding, deleting, or modifying them.

[0039] A map annotation task refers to one of the tasks in the map production process, which can include plan creation, production, quality inspection, and acceptance. A map annotation task is a map data production task used to produce map data based on collected map data, thereby generating a map, such as a high-precision map. The map data can be high-precision map data.

[0040] Due to the complexity of maps, in the production process, it is usually carried out in parallel by region or element, that is, the map annotation task can be divided into at least two tasks (including the first task and the second task), and these at least two tasks are carried out in parallel. Since the map data between regions or elements are bound to be related, the map data of different tasks need to be associated, that is, connected. Completing the entire map annotation task is not only about completing these at least two tasks in parallel, but also about completing the connection work between the map data of different tasks. That is, the map annotation task is completed only after the parallel tasks and the connection work of the parallel tasks are completed.

[0041] In related technologies, different tasks are usually independent operations. After the entire task is completed, the edge connection task is triggered to connect the map data produced by different tasks to achieve the purpose of associating different areas or different elements. However, the application scenario is only suitable for small-scale production and not suitable for large-scale mass production. For city-level scopes, the amount of data is too large to load the entire map assembly data at one time to connect the map data of different tasks. And the higher the parallelism, the greater the workload of connecting (i.e., edge connection) the map data between parallel tasks after the parallel operation is completed. This will increase the map production cycle and thus reduce the efficiency of map production.

[0042] This embodiment aims to complete the map data connection work between different tasks in advance during the parallel operation stage without reducing the parallelism of the map annotation task, i.e., the map data operation, and integrate the connection work into the map data annotation (i.e., operation) process. This can reduce the time consumption of task flow and reduce the workload of connection between map data of parallel tasks, thereby shortening the cycle of high-precision map production and improving the efficiency of high-precision map production.

[0043] On the premise that the map annotation task is divided into at least two parallel tasks, different tasks are scheduled by different electronic devices. For example, the first electronic device schedules the first task to annotate the map data corresponding to the first task, and the second task can be scheduled by other electronic devices to annotate the map data corresponding to the second task. The map data annotated by different tasks are at least partially different.

[0044] During the map data production process of the first task in the map annotation task scheduling, it is possible to monitor whether there are data interaction instructions. The data interaction instructions may indicate that the map data annotated in the first task interacts with the map data annotated by another task in the map annotation task (such as the second task). Interaction means that the map data of different tasks need to be connected.

[0045] For example, interaction can involve connecting map data for the same feature across different tasks. For example, if the first task includes map data for drawing a lane line, but the end of the lane line is outside the first task's map data, meaning that another task also includes map data for the same lane line, then the map data for the lane line in the different tasks needs to be connected.

[0046] For another example, the interaction may include the association relationship between different elements in different tasks, such as the stop line in the first task and the traffic light in the second task need to be bound, and the road in the first task and the road in the second task need to be bound.

[0047] In an optional embodiment, the operator can manually identify the scenes that need to be connected during the operation of the first task. When it is determined that the first map data (which can be map data of a certain element) needs to be connected with the second map data of another task (which can be a second task), an operation can be triggered (such as clicking a certain control). Accordingly, the first electronic device can determine the data interaction instructions monitored for the first map data.

[0048] In another optional embodiment, the user may interact with the map data during manual work, such as using a mouse to indicate map data or using a keyboard to locate map data. In this scenario, upon receiving an interactive operation of the user on the first map data (such as a mouse or keyboard positioning operation, etc.), the interactive operation may be analyzed based on a pre-established data association relationship to determine whether the data association relationship includes an association relationship with the first map data indicated by the interactive operation. If so, it is determined that the data interaction instruction of the first map data is monitored.

[0049] Among them, the data association relationship may include the association relationship between the map data of different tasks in the map annotation task. For example, the first task includes the map data operation of lane line A, and the second task also includes the map data operation of lane line A. Before the task is scheduled, the association relationship between the first task and the second task regarding the map data of lane line A can be pre-constructed to obtain the data association relationship and store it in the second electronic device. When the first electronic device schedules the first task, the second electronic device can send the data association relationship corresponding to the first task to the first electronic device along with the task.

[0050] The second electronic device may be a remote management device having both data storage and data management functions. The data storage function refers to its ability to store map data. When each task in a map annotation task completes the map data annotation of each element, the electronic device that schedules the task may upload the map data of the annotated element to the second electronic device. The data management function refers to its ability to manage the map data of each task in the map annotation task. For example, for each task in the map annotation task, permissions for the task's map data may be set, as well as permissions for the task's map data on other tasks.

[0051] When the first electronic device monitors the data interaction instruction of the first map data, it may send a permission application request to the second electronic device based on the data interaction instruction. The permission application request is used to request the first task to have write permission for the second map data.

[0052] The second map data is the map data processed in the second task (different from the first task and running in parallel with the first task) of the map annotation task, and is the map data that interacts with the first map data. The second map data that interacts with the first map data indicated by the data interaction instruction can be obtained by manual annotation or by querying data association relationships.

[0053] The permission application request may include identifiers of the first task and the second task indicated by the data interaction instruction, identifiers of elements of the first map data operated in the first task, and identifiers of elements of the second map data operated in the second task.

[0054] Step S102: When the second map data is loaded from the second electronic device in a read-only manner and first feedback information returned by the second electronic device in response to the permission application request is received, map production is performed based on the first map data and the second map data, and the first feedback information indicates that the first task has writable permission for the second map data.

[0055] In this embodiment, the map data can be distinguished between read-only and writable. The map data within the scope of the first task is writable data, that is, the first electronic device can schedule the first task to produce map data. During the production process, the user can edit the map data within the scope of the first task (such as adding new elements, modifying elements, etc.). After the element marking is completed, the marked map data can be uploaded to the second electronic device. Correspondingly, the second electronic device can store the map data uploaded by the first electronic device. This process can be called the writing process of the map data within the scope of the first task. In other words, for the first task, the map data within its scope has writable permission relative to the second electronic device, and it can write the map data within the scope to the second electronic device.

[0056] Map data outside the scope of the first task, i.e., other tasks, is read-only data. The first electronic device can load the map data of other tasks (including the second map data) in read-only mode. Loading the map data of other tasks in read-only mode means that the first electronic device can load the map data of other tasks, but it only has read-only permission for the map data and does not have write permission for the map data.

[0057] Read-only permission means that the first electronic device cannot edit the map data of other tasks during the process of scheduling the first task, or, although it can edit locally, it cannot upload the edited data to the second electronic device, and thus cannot change the corresponding map data in the second electronic device.

[0058] The first electronic device can load map data of other tasks from the second electronic device through the loading address. During the process of the first electronic device loading the map data of other tasks, the second electronic device can identify whether the first task is consistent with the task corresponding to the loaded map data. If they are inconsistent, the map data of the other task can be bound to a read-only permission identifier, so that the first electronic device can only load the map data of the other task in a read-only manner.

[0059] When the electronic device that schedules each task in the map annotation task completes the map data annotation of an element (one element can correspond to one subtask), the marked map data can be uploaded to the second electronic device. Accordingly, after receiving the map data of each task in the map annotation task, the second electronic device can store it in the corresponding location and generate a loading address for the map data. The loading address can be sent to the first electronic device in real time, periodically, or when the first electronic device schedules the first task, so that the first electronic device can load the map data of other tasks.

[0060] That is to say, the first electronic device can load the second map data from the second electronic device in a read-only manner (which can be bound to an identifier of read-only permission) based on the loading address of the second map data. The timing of loading the second map data can be when the first electronic device obtains the loading address of the second map data, or when the first electronic device monitors the data interaction instruction of the first map data, that is, the scenario where the first task triggers the connection.

[0061] When the second electronic device obtains the map data, it may also automatically push the map data of other tasks to the first electronic device in a read-only manner, so that the first electronic device can load the second map data.

[0062] When the second electronic device receives the permission application request, it can determine whether the writable permission of the second map data is occupied by other tasks (such as the third task) in the map annotation task other than the second task (i.e., the second map data itself task), and whether the first task can occupy the writable permission of the second map data. If the writable permission of the second map data is not occupied by other tasks in the map annotation task other than the second task, and the first task has the conditions to occupy the writable permission of the second map data, the second electronic device will return first feedback information to the first electronic device, and the first feedback information indicates that the first task has writable permission for the second map data.

[0063] Correspondingly, when the first electronic device is loaded with the second map data and has writable permission for the second map data, the task type can be converted from annotation to edging, and the edging process can be entered to produce a map based on the first map data and the second map data, that is, to connect the first map data and the second map data. After the edging process is completed, the first electronic device can upload the connected map data to the second electronic device for storage. In this way, the edging work can be completed in the annotation stage, and the annotation and edging work can be completed together.

[0064] In this embodiment, by distinguishing between read-only and writable map data, all map data marked by each task can be loaded, and the map data within the task range is writable data, while the map data of other tasks outside the task range is loaded in read-only mode. In this way, during the process of the first electronic device scheduling the first task to produce map data, if the data interaction instruction of the first map data in the first task is monitored, the second electronic device can be applied for the writable permission of the map data of other tasks. After obtaining the writable permission, the first map data can be connected with the loaded map data of other tasks. In this way, the connection can be triggered in real time, and the connection work content can be advanced to the marking link as much as possible, reducing the time consumption of task flow. After completing an element, this element can be connected with the elements in other tasks, which can maximize the efficiency of the connection and thus improve the efficiency of map production.

[0065] Optionally, before step S102, the following steps may be further included:

[0066] generating a connection record for the first map data if the second map data is not loaded from the second electronic device or if second feedback information returned by the second electronic device in response to the permission application request is received, wherein the second feedback information indicates that the first task does not have writable permission for the second map data;

[0067] The connection record is sent to the second electronic device, so that the second electronic device triggers pushing first target data to the first electronic device based on the connection record, where the first target data includes the second map data and / or the first feedback information.

[0068] In this embodiment, in one scenario, the second electronic device has not received the second map data sent by the electronic device that schedules the second task, that is, the second task has not yet completed the annotation of the map elements corresponding to the second map data. At this time, the first electronic device cannot load the second map data from the second electronic device.

[0069] In another scenario, when the second electronic device receives the permission application request sent by the first electronic device, it can determine whether the first task can occupy the writable permission for the second map data. If the first task does not have the writable permission for the second map data (for example, the writable permission for the second map data is occupied by another task), the second electronic device can send second feedback information to the first electronic device. Correspondingly, the first electronic device can receive the second feedback information returned by the second electronic device in response to the permission application request.

[0070] In these scenarios, the first electronic device does not have permission to connect, and may generate a connection record for the first map data. The connection record may include a connection location, indicating map data required for connection in different tasks.

[0071] Afterwards, the connection record can be sent to the second electronic device, which can store the connection record and wait for a triggering opportunity, such as receiving the second map data or monitoring that other tasks release the occupation of the second map data. At this time, it can trigger the push of the first target data to the first electronic device.

[0072] Accordingly, when the first electronic device loads the second map data from the second electronic device and receives the first feedback information, it generates a map based on the first map data and the second map data.

[0073] In this embodiment, when loading the second map data fails or applying for the writable permission for the second map data fails, a connection record can be generated and stored in the second electronic device, waiting for the writable permission for the second map data to be released, that is, the task occupying the writable permission for the second map data is completed, and then the connection is triggered. In this way, the connection process of each task can be guaranteed to proceed normally.

[0074] Optionally, the method further includes:

[0075] upon receiving third feedback information returned by the second electronic device in response to the permission application request, pushing the first map data to a third electronic device, so that the third electronic device generates a map based on the first map data and the second map data during a process of generating map data for the third task in scheduling the map annotation task;

[0076] The third feedback information indicates that the third task occupies the writable permission for the second map data.

[0077] In this embodiment, the first electronic device may also send the first map data to the third electronic device, and the third electronic device completes the connection work.

[0078] Specifically, upon receiving the permission request sent by the first electronic device, the second electronic device may determine whether the writable permission for the second map data is occupied by another task. If it is monitored that the writable permission for the second map data is occupied by a third task, the second electronic device may send third feedback information to the first electronic device. Correspondingly, the first electronic device may receive the third feedback information returned by the second electronic device in response to the permission request.

[0079] When the third feedback information is received and the subtask corresponding to the first map data is completed, the first map data can be pushed to the third electronic device through the second electronic device, so that the third electronic device can produce a map based on the first map data and the second map data during the process of producing map data for the third task in the scheduling of map annotation tasks.

[0080] In this embodiment, if the write permission for the second map data is occupied by the third task, the first electronic device can push the first map data to the third electronic device that invokes the third task through the second electronic device. The third electronic device can then directly complete the merging process based on the first and second map data. This way, even if the write permission for the second map data is occupied, the merging process does not need to wait, thereby maximizing the efficiency of merging.

[0081] Optionally, the method further includes:

[0082] When receiving an interactive operation of the user on the first map data, if an association relationship of the first map data is found from the pre-built data association relationship, it is determined that the data interaction instruction is monitored;

[0083] The data association relationship includes the association relationship between map data of different tasks in the map annotation task.

[0084] In this embodiment, the user will interact with the map data during the manual operation process, such as pointing to the map data with a mouse and locating the map data with a keyboard. In this scenario, when receiving the user's interactive operation on the first map data (such as positioning operation of the mouse and keyboard, etc.), the interactive operation can be analyzed based on the pre-built data association relationship to determine whether the data association relationship includes the association relationship of the first map data indicated by the interactive operation. If included, it is determined that the data interaction instruction of the first map data is monitored.

[0085] Among them, the data association relationship may include the association relationship between the map data of different tasks in the map annotation task. For example, the first task includes the map data operation of lane line A, and the second task also includes the map data operation of lane line A. Before task scheduling, the association relationship between the first task and the second task regarding the map data of lane line A can be pre-constructed to obtain the data association relationship and store it in the second electronic device.

[0086] When the first electronic device schedules the first task, the second electronic device can send the data association relationship corresponding to the first task to the first electronic device along with the task. Accordingly, the first electronic device can query the association relationship of the first map data from the data association relationship.

[0087] When the first electronic device receives a user's interactive operation on map data, it can send a query instruction to the second electronic device, and the second electronic device queries the association relationship of the first map data indicated by the interactive operation from the data association relationship, and returns the query result to the first electronic device.

[0088] In this way, when labeling, the analysis of human interaction based on data association relationships can be used to dynamically determine whether to perform edge connection. This does not require manual understanding of the edge connection logic, nor does it require manual demarcation of edge connection tasks. Edge connection can also be triggered in real time, thereby reducing labor costs.

[0089] Optionally, before step S102, the following steps may be further included:

[0090] receiving a loading address sent by the second electronic device, where the loading address is used to load the second map data from the second electronic device;

[0091] sending a loading request to the second electronic device based on the loading address;

[0092] Second target data sent by the second electronic device in response to the loading request is received, where the second target data includes the second map data, and the second target data indicates that the first task has read-only permission to the second map data.

[0093] In this embodiment, when the second electronic device receives the map data, it can generate a loading address and send the loading address to other tasks in real time, periodically, or as the task is scheduled. For example, the second electronic device will send the loading address of the map data of other tasks to the first electronic device that schedules the first task. At the same time, it will limit the first task's permission to these map data to read-only permission, so that the first electronic device can only load the map data of other tasks in a read-only manner based on the loading address.

[0094] Correspondingly, the first electronic device can receive the loading address sent by the second electronic device and send a loading request to the second electronic device based on the loading address. The sending timing can be when the loading address is obtained or when applying for write permission to the second electronic device.

[0095] When the second electronic device receives the loading request, it can send the second target data to the first electronic device. The second target data can carry the second map data and can also carry an identifier indicating that the first task has only read-only permission to the second map data. In this way, the first electronic device loads the second map data in a read-only manner.

[0096] In this embodiment, the loading address of the map data of other tasks is sent by the second electronic device, so that the electronic device of the scheduling task can load the map data of other tasks. In this way, not only can each task in the map annotation task be opened, but also the freedom of loading the map data of other tasks can be achieved (for example, map data can be loaded at any time based on the loading address).

[0097] Second embodiment

[0098] like Figure 2 As shown, the present disclosure provides a method for producing a high-precision map, which is applied to a second electronic device and includes the following steps:

[0099] Step S201: receiving a permission application request sent by a first electronic device during a process of producing map data for a first task in a scheduled map annotation task, wherein the permission application request is sent by the first electronic device based on a data interaction instruction of first map data in the first task when the first electronic device monitors the data interaction instruction, the data interaction instruction indicating that data interaction exists between the first map data and a second task in the map annotation task, and the permission application request is used to request the first task to have write permission for second map data, where the second map data is map data in the second task that has data interaction with the first map data;

[0100] Step S202: if it is monitored that the writable permission of the second map data is not occupied by any task other than the second task in the map annotation task, changing the permission of the first task on the second map data from read-only permission to writable permission;

[0101] Step S203: Sending first feedback information to the first electronic device so that the first electronic device produces a map based on the first map data and the second map data pre-loaded in read-only mode from the second electronic device, wherein the first feedback information indicates that the first task has writable permission for the second map data.

[0102] In this embodiment, when the first electronic device is producing map data for the first task in the scheduled map annotation task, if it monitors a data interaction instruction for the first map data in the first task, it sends a permission request to the second electronic device based on the data interaction instruction. Accordingly, the second electronic device can receive the permission request sent by the first electronic device.

[0103] The permission application request may include the identifiers of the first task and the second task indicated by the data interaction instruction, the element identifier of the first map data operated in the first task, and the element identifier of the second map data operated in the second task.

[0104] When the second electronic device receives the permission application request sent by the first electronic device, it can monitor whether the writable permission of the second map data is occupied by other tasks in the map annotation task except the second task. For example, if the flag of the writable permission of other tasks for the second map data is set to 1, it is determined that the writable permission of the second map data is occupied by other tasks in the map annotation task except the second task. Otherwise, it is determined that the writable permission of the second map data is not occupied by other tasks in the map annotation task except the second task.

[0105] Correspondingly, when it is monitored that the writable permission of the second map data is not occupied by other tasks in the map annotation task except the second task, the permission of the first task to the second map data is changed from read-only permission to writable permission. Specifically, the writable permission of the first task to the second map data can be set to 1. In this way, the first task has writable permission to the second map data, that is, it can edit the second map data.

[0106] Afterwards, first feedback information indicating that the first task has write permission for the second map data can be sent to the first electronic device, so that the first electronic device can produce a map based on the first map data and the second map data and complete the marking and edge connection work.

[0107] In this embodiment, a permission application request for the second map data that needs to be connected to the first map data in the second task is received by the second electronic device, and the permission of the second map data is set based on the permission application request, so that the first task has writable permission for the second map data. In this way, the first electronic device can schedule the first task to produce a map based on the first map data and the second map data, so that the connection can be triggered in real time, and the connection work content can be advanced to the annotation link as much as possible, reducing the time consumption of task flow. After completing an element, this element can be connected to the elements in other tasks, which can maximize the efficiency of the connection and thus improve the efficiency of map production.

[0108] Optionally, the method further includes:

[0109] sending third feedback information to the first electronic device when it is monitored that the writable permission of the second map data is occupied by the third task in the map annotation task;

[0110] upon receiving the first map data sent by the first electronic device in response to the third feedback information, changing the permission of the third task on the first map data from read-only permission to writable permission;

[0111] The fourth feedback information and the first map data are sent to a third electronic device that schedules the third task, so that the third electronic device produces a map based on the first map data and the second map data, and the fourth feedback information indicates that the third task has writable permission for the first map data.

[0112] In this embodiment, if it is monitored that the writable permission of the third task to the second map data is set to 1, it can be determined that the writable permission of the second map data is occupied by the third task. At this time, the third feedback information can be sent to the first electronic device to inform the first electronic device that the writable permission of the second map data is occupied by the third task, and the first task cannot obtain the writable permission of the second map data at this time.

[0113] In order to improve the efficiency of the connection, the first electronic device can upload the first map data to the second electronic device when completing the subtask of the first map data. When the second electronic device receives the first map data, it can change the permission of the third task to the first map data from read-only permission to write permission, and push the first map data to the third electronic device that schedules the third task, so that the third electronic device can complete the connection work between the map data of the first task and the second task when occupying the second map data.

[0114] Optionally, the method further includes:

[0115] generating a loading address upon receiving the second map data;

[0116] sending the loading address to the first electronic device;

[0117] The loading address is used to load the second map data from the second electronic device.

[0118] In this embodiment, the map data of each task in the map annotation task is released through the second electronic device. Specifically, when the map data of other tasks (including the second map data) is received, a loading address can be generated and the loading address can be sent to the electronic device that schedules the task (including the first electronic device), so that the first electronic device that schedules the first task can load the map data of other tasks through the loading address, which lays the foundation for the connection work between the first task and other tasks.
