Fig. 2 is another schematic flow chart of a method for generating a traffic integration rod according to an embodiment of the present application. Fig. 2 depicts the solution of the present application in more detail with respect to fig. 1.
Referring to fig. 2, the method includes:
step S201, one traffic management device generated on the map is selected, and other traffic management devices are searched in a preset range near the traffic management device to obtain all the traffic management devices corresponding to the same traffic integrated pole.
Wherein the map may be a high-precision map.
Wherein, the traffic management equipment is one of traffic signal lamp, traffic monitoring equipment and traffic sign board. The traffic signal lamp can be a traffic light, and the traffic signal lamp can be a traffic signal lamp formed by a single signal lamp, a transverse or longitudinal traffic signal lamp formed by combining a plurality of signal lamps in parallel and the like; the traffic monitoring equipment can be a monitoring camera, a radar detector and the like.
In the embodiment of the application, the traffic management device is generated on the map in a line segment form. That is, the traffic management device generated on the map is represented by a line segment, and two end points of the line segment represent two edge end points of the traffic management device. Further, the traffic management device may be generated as directed line segments on the map.
In this step, one traffic management device generated on the map is selected, and then other traffic management devices are searched within a preset range near the traffic management device.
For example, a central point of the traffic management device on a map is used as a central point of a preset rectangular frame, and all traffic management devices in the preset rectangular frame are searched; the direction of the short side of the preset rectangular frame is the driving advancing direction of the road, the length of the short side of the preset rectangular frame is a first set value, and the length of the long side of the preset rectangular frame is a second set value; the first set value may take 0.5 meters, 0.8 meters, etc., and the second set value may take 4 meters, 5 meters, etc. For another example, all traffic management devices within N meters of the radius are searched with the center point of the traffic management device on the map as the center, and N may take a numerical value greater than zero, such as 2, 4, and the like. Thus, each traffic management device corresponding to the same traffic integrated pole can be acquired. That is, it can be considered that the searched traffic management apparatuses are installed on the same traffic integrated pole.
Referring to fig. 3, the line segment a, the line segment b, and the line segment c shown in fig. 3 are a plurality of traffic management devices generated on a map, and according to the present application, one of the traffic management devices (for example, the line segment b) may be selected, and other traffic management devices may be searched within a preset range near the traffic management device, so that the line segment a, the line segment b, and the line segment c may be searched. Thus, the line segment a, the line segment b, and the line segment c can be regarded as respective traffic management devices on the same traffic integrated pole.
And step S202, acquiring each searched traffic management device.
In this step, each traffic management device obtained by the search is acquired. It can be understood that the acquired traffic management devices belong to the same traffic integrated pole.
Step S203, according to the plurality of traffic management devices, selecting one traffic management device far away from the outer lane line of the corresponding road in the map as a first traffic management device, and selecting one traffic management device adjacent to the outer lane line of the corresponding road in the map as a second traffic management device.
In the embodiment of the present application, in one of the embodiments, the outer lane line is a lane line on the road far from the adjacent reverse road, that is, the outer lane line is a lane line on each lane near the roadside. In another embodiment, the outer lane line is the rightmost lane line in the advancing direction of the road.
In other embodiments, in one of the embodiments, the outer lane line is a lane line adjacent to the opposite road beside the road, that is, the outer lane line is a lane line far away from the roadside in each lane of the road. In another embodiment, the outer lane line is the leftmost lane line in the advancing direction of the road.
In this step, one traffic management device away from the outside lane line of the corresponding road in the map is selected as the first traffic management device, that is, one traffic management device away from the outside lane line of the road is selected as the first traffic management device on the road on which each traffic management device is located. Referring to fig. 3, a line segment a representing the traffic management device shown in fig. 3 may be selected as the first traffic management device. One traffic management device adjacent to the outer lane line of the corresponding road in the map is selected as the second traffic management device, that is, one traffic management device adjacent to the outer lane line of the road is selected as the second traffic management device on the road where each traffic management device is located. Referring to fig. 3, a line segment c representing the traffic management device shown in fig. 3 may be selected as the second traffic management device. That is, in the embodiment shown in fig. 3, the line segment a represents the first traffic management device, and the line segment c represents the second traffic management device.
Step S204, taking the edge end point far away from the outer lane line on the first traffic management device as a first end point, and taking the edge end point close to the outer lane line on the second traffic management device as a second end point.
It is understood that, since the traffic management devices are generated on the map in the form of line segments, the first end point is the end point far from the outside lane line on the line segment represented by the first traffic management device, and the second end point is the end point near the outside lane line on the line segment represented by the second traffic management device. Referring to fig. 3, in the embodiment shown in fig. 3, an end point on the line segment a far from the outside lane line may be used as a first end point, and an end point on the line segment c near the outside lane line may be used as a second end point.
In the embodiment of the application, the traffic management device may be generated on the map in the form of a directed line segment. That is, each line segment has a direction, i.e., a starting point and an ending point. In the embodiment of the application, the starting point of the line segment can be set to be far away from the end point of the outer lane line, and the end point of the line segment can be set to be close to the end point of the outer lane line. In the embodiment shown in fig. 3, the starting point S on the line segment a serves as the first end point, and the ending point E on the line segment c serves as the second end point.
Each line segment representing each traffic control device has its corresponding coordinate position on the map. According to the coordinates of the starting point and the ending point of each line segment, the tasks of selecting the first traffic management device, the second traffic management device, the first end point and the second end point can be realized.
And S205, selecting an intersection point of the straight line and the outer lane line according to the straight lines determined by the first end point and the second end point.
In this step, the first end point and the second end point may be connected to generate a straight line, and then an intersection point where the straight line intersects the outside lane line may be selected. Referring to fig. 4, the point P shown in fig. 4 is the intersection point.
And S206, generating a traffic comprehensive pole according to the first end point and the intersection point.
In one embodiment, generating the traffic integration rod according to the first endpoint and the intersection point may include:
and taking the first end point and the intersection point as two end points of the traffic comprehensive pole to be generated to generate the traffic comprehensive pole. That is, the generated traffic integrating bar may be displayed on the map with both end points being line segments of the first end point and the intersection point, respectively.
In another embodiment, generating a traffic integration rod according to the first endpoint and the intersection point may include:
and constructing a set line segment according to the first end point and the intersection point, respectively selecting two set points on the extension lines at the two ends of the set line segment, and generating the traffic comprehensive pole by taking the two set points as the two end points of the traffic comprehensive pole to be generated.
In the step, two end points of the line segment are set as a first end point and an intersection point, the first end point, the intersection point and the two set points are collinear, and the generated traffic comprehensive rod is displayed on a map by using the line segments with the end points at the two ends as the two set points respectively.
Further, the two set points include a first set point and a second set point; the first set point is adjacent to the first end point and is a first preset distance away from the first end point; the second set point is adjacent to the intersection point and is a second predetermined distance from the intersection point.
Referring to fig. 4, the first end point of the line segment is set as the starting point S of the line segment a, and the intersection point of the line segments is set as the intersection point P. The first set point adjacent to the first end point is a point
The second set point adjacent to the intersection point being a point
. The first predetermined distance is the distance between the first end point and the first set point, and the second predetermined distance is the distance between the intersection point and the second set point. The first predetermined distance and the second predetermined distance may be the same or different. The first preset distance and the second preset distance can be 0.3 meter, 0.4 meter, 0.5 meter and the like.
It will be appreciated that the end of both ends of a traffic integration rod in the real world will not normally be equipped with traffic management equipment. The design specification of the traffic comprehensive pole in the real world is represented by setting the first preset distance and the second preset distance.
And step S207, regenerating each traffic management device according to the feet of the two side edge end points of each traffic management device on the traffic comprehensive rod.
In the related art, in the vehicle driving process, the vehicle camera device is used, And according to an image recognition technology based on deep learning And a SLAM (Simultaneous Localization And Mapping) technology, each traffic management device recognized by the vehicle can be generated on a map. It will be appreciated that where the traffic integration rod is positioned across the roadway, the individual traffic management devices on the traffic integration rod should be collinear, i.e., in a straight line. However, due to the existence of errors, the generated line segments representing the traffic management devices may have the problem of inaccurate positions, that is, the line segments representing the traffic management devices are not collinear, and it is difficult to correctly generate the traffic management devices on the map, which can represent the traffic integrated lever in the real world.
In the embodiment of the present application, for each generated traffic management device (e.g., line segment a, line segment b, and line segment c shown in fig. 3 or fig. 4), each traffic management device is newly generated according to the drop foot of the two side edge end points of each traffic management device on the traffic integration rod. Therefore, each generated traffic management device can be corrected, the refinement degree of the high-precision map is improved, and the map manufacturing optimization work is realized.
Please refer to fig. 5, which is a line segment shown in fig. 5
Line segment

The traffic management devices that are regenerated are respectively shown (corresponding to line segment a, line segment b, and line segment c in fig. 3 or fig. 4, respectively, before regeneration). It can be seen that the regenerated individual traffic management devices (line segments as shown in FIG. 5)

) Are collinear and the regenerated individual traffic management devices are on the generated traffic integration rod. In this way, the traffic integrated pole and the traffic management devices can be generated on the map, and the generated traffic management devices are collinear, so that the traffic management devices on the same traffic integrated pole in the real world can be correctly represented.
According to the embodiment, the method provided by the embodiment of the application can be used for generating the traffic comprehensive pole in the high-precision map, and can be used for revising each generated traffic management device on the map, so that the manufacturing of the high-precision map is further refined and optimized, and the navigation assistance effect of the high-precision map is favorably improved.
