The embodiment of the present disclosure provides a method of processing map data, and a method of processing map data according to an exemplary embodiment of the present disclosure is described below with reference to fig. 2 to 8 in conjunction with the application scenario of fig. 1.
Fig. 2 schematically illustrates a flowchart of a method of processing map data according to an embodiment of the present disclosure.
As shown in fig. 2, the method 200 of processing map data of the embodiment of the present disclosure may include, for example, operations S210 to S230.
In operation S210, traffic data is processed to obtain object data of a traffic indication object.
In operation S220, road data of the target road is determined based on at least one of the object data of the traffic indication object and the object data of the traffic reference object.
In operation S230, map data is updated based on the road data.
By way of example, traffic data is acquired, for example, by an acquisition device, the traffic data including information of traffic indicating objects, information about roads, and the like. The object data of the traffic indication object can be obtained by processing the traffic data. For example, the traffic data includes an image, and the object data of the traffic indicating object can be obtained by image recognition of the image.
The object data of the traffic indication object indicates, for example, information of a target road. For example, the object data of the traffic indicating object characterizes the type of road, the position of the road, the transit time of the road, and the like.
For example, a traffic reference object may be determined based on the traffic indication object, the object data of the traffic reference object being associated with the object data of the traffic indication object, e.g., the traffic reference object and the traffic indication object being located adjacent. Embodiments of the present disclosure may determine road data of a target road based on at least one of object data of a traffic indication object and object data of a traffic reference object, the road data of the target road including, for example, a position of the road, a transit time of the road, and the like.
After the road data of the target road is determined, the map data may be updated based on the road data so as to perform navigation based on the updated map data.
According to an embodiment of the present disclosure, object data of a traffic indication object is obtained by processing traffic data, and then road data of a target road is determined based on the object data of the traffic indication object and the object data of a traffic reference object associated therewith, so that map data is updated based on the road data. Therefore, by the embodiment of the disclosure, the updating efficiency of the map data is improved, and the updating cost of the map data is reduced, so that the navigation accuracy is improved.
In another embodiment of the present disclosure, the traffic indicating object comprises, for example, a traffic sign, also known as a sign, and the traffic reference object comprises, for example, a road marking.
The target road includes, for example, a bus lane, and the road data includes at least one of road position data and road traffic time data. When the target road is a bus lane, the traffic sign indicates that the front road or the current road is a bus lane, for example, the road mark is a yellow mark, and indicates that the current road is a bus lane.
The object data of the traffic sign and the object data of the road marking each include, for example, position data and a time range, which indicates, for example, that the target road is a bus lane within the time range. The time ranges include, for example, 7:30-9:30 and 17:30-19:30 per day of work.
Fig. 3 schematically illustrates a schematic diagram of a method of processing map data according to an embodiment of the present disclosure.
As shown in fig. 3, the traffic indication object includes at least two, including, for example, a traffic indication board 310 and a traffic indication board 320, and the traffic indication board 310 and the traffic indication board 320 indicate, for example, a target road (bus lane). The object data of the traffic sign 310 and the traffic sign 320 include, for example, position data of the traffic sign.
Illustratively, the position data of the two traffic indicating objects are determined as the start position and the end position of the target link 330, respectively, and then the position data of the target link 330 is determined as the link data based on the start position and the end position.
For example, the position data of the traffic sign 310 is determined as the start position of the target link 330, and the position data of the traffic sign 320 is determined as the end position of the target link 330. The position data of the target link 330 can be known from the position data of the traffic sign, and then the map data is updated based on the position data of the target link 330. For example, if there is no road data of the target road 330 in the map data, the road data of the target road 330 is added to the map data, or if there is history road data for the target road 330 in the map data, the road data of the target road 330 is replaced with the history road data in the map data. The road data includes, for example, road position data of the target road.
According to the embodiment of the disclosure, the position data of the traffic indication object is obtained by processing the traffic data, and then the road data of the target road is determined based on the position data of the traffic indication object, so that the map data is updated based on the road data, the updating efficiency of the map data is improved, and the updating cost of the map data is reduced.
Fig. 4 schematically illustrates a schematic diagram of a method of processing map data according to another embodiment of the present disclosure.
As shown in fig. 4, the traffic indication object includes at least two, for example, includes a traffic indication board 410 and a traffic indication board 420, and the traffic indication board 410 and the traffic indication board 420 indicate a target road (bus lane), for example. The object data of the traffic sign 410 and the traffic sign 420 include, for example, position data of the traffic sign.
For example, the position data of the traffic reference object is determined as road data based on the position data of the two traffic indication objects, and the position data of the traffic reference object is determined from the traffic data.
For example, the target reference object includes a road marking, such as a yellow marking, for indicating that the current road is a bus lane. Based on the position data of the traffic sign 410 and the traffic sign 420, road markings around the traffic sign are determined, and the road on which the determined road markings are located is the target road 430. The position data of the target road 430 can be known from the position data of the road markings, and then the map data is updated based on the position data of the target road 430. For example, if there is no road data of the target road 430 in the map data, the road data of the target road 430 is added to the map data, or if there is history road data for the target road 430 in the map data, the road data of the target road 430 is replaced with the history road data in the map data.
The position data of the two traffic indication objects are, for example, within a range of position data indicated by the position data of the traffic reference object. For example, the length of the road markings typically includes the length from traffic sign 410 to traffic sign 420.
Since the traffic sign 410 and the traffic sign 420 are not necessarily located at the start point and the end point of the target road, there is a case where the target road determined based on only the position data of the traffic sign 410 and the traffic sign 420 is incomplete. Accordingly, surrounding road markings are determined based on the traffic signs 410 and 420, and a target road is determined based on the road markings, so that the determined target road is more complete and accurate.
According to the embodiment of the disclosure, the position data of the traffic indication object is obtained by processing the traffic data, then the position data of the traffic reference object is determined based on the position data of the traffic indication object, and the road data of the target road is determined based on the position data of the reference object, so that the map data is updated based on the road data, the accuracy of the road data is improved, and the updating efficiency of the map data is improved.
Fig. 5 schematically illustrates a schematic diagram of a method of processing map data according to another embodiment of the present disclosure.
As shown in fig. 5, after the road data of the target road 530 is determined based on the traffic sign 510 and the traffic sign 520, the object data of the traffic target object associated with the target road 530, including, for example, an intersection, which is located in the target road 530, may be determined from the map data based on the road data. The object data of the traffic target object includes, for example, position data of an intersection, detailed description data, and the like. The target road 530 includes, for example, a road link L1 and road links L3 to L9.
Next, the object data of the traffic indicating object and the object data of the traffic target object are associated so that the target road can be indicated by the traffic target object. For example, the data of intersection B and the data of intersection C are correlated to the object data of traffic sign 510 (or the object data of traffic sign 520). After the data association is performed, when the vehicle runs to the intersection B and the intersection C in the navigation process, the user can be prompted that the current road is a bus lane.
And when the change of the object data of the traffic indication object is determined, updating the object data of the traffic target object according to the data association relation. For example, after the object data of the traffic indication object is changed, if the changed object data indicates that the road is a non-bus lane, the association relationship between the intersection B and the intersection C and the object data of the traffic indication board 510 (or the object data of the traffic indication board 520), that is, the intersection B and the intersection C indicated in the map data are no longer located in the bus lane, may be deleted. In the navigation process, when the vehicle runs to the intersection B and the intersection C, the user is not prompted any more that the current road is a bus lane.
According to the embodiment of the disclosure, the object data of the traffic indication object and the object data of the traffic target object are associated, so that the current position is prompted to be a target road when the vehicle passes through the traffic target object. In addition, by storing the data in an associated manner, the object data of the traffic target object can be updated when the object data of the traffic indication object is changed, so that the updating efficiency of the map data is improved.
Fig. 6 schematically illustrates a schematic diagram of vehicle navigation according to an embodiment of the present disclosure.
As shown in fig. 6, when the vehicle is traveling from the intersection a to the intersection B, for example, when the vehicle is turning left from the road segment L2 to the road segment L1, and the current time is 7:30-9:30 and 17:30-19:30 of the working day, the navigation system may make a notification that the vehicle is about to enter the bus lane.
Fig. 7 and 8 schematically illustrate diagrams of data storage according to an embodiment of the present disclosure.
As shown in fig. 7, data of traffic entities including traffic signs, road markings, traffic indication arrows, and the like are stored. The disclosed embodiments describe the storage of data using traffic signs as an example.
For the data of each traffic sign, the main data of the traffic sign is stored by a lane_mark table, the main key of which is a MARK number (mark_id) for uniquely representing the traffic sign. The primary data of the traffic sign also includes the type of sign, associated road, primary coordinates, projected coordinates, etc. The type of marking is used to represent the type of traffic entity, including, for example, traffic signs, road markings, traffic indication arrows, and the like. The associated road, for example, characterizes the road on which the traffic sign is located. The raw coordinates, for example, characterize the absolute position of the traffic sign. The projection coordinates represent, for example, the projection position of the traffic sign on the road.
For the data of each traffic sign, the auxiliary data of the traffic sign is stored through a mark_info table. The assist data includes, for example, a tag detailed information number, a tag type, a number of lanes, arrow information, a lane number, a lane type, a vehicle type, time information, and the like.
As shown in fig. 8, a traffic sign 810 and a traffic sign 820 are illustrated as examples. Traffic sign 810 is also denoted as sign 1 and traffic sign 820 is also denoted as sign 2. The data storage of traffic sign 810 and traffic sign 820 is shown in fig. 8. The associated road of the traffic sign 810 is, for example, the road segment L1, the associated road of the traffic sign 820 is, for example, the road segment L5, and the road segment L1 and the road segment L5 may be as shown with reference to fig. 5.
According to the embodiment of the disclosure, the data of the traffic entity is stored in the map data according to the data storage mode of the embodiment of the disclosure, so that the map data is convenient to update and maintain, and the update efficiency of the map data is improved.
