The accuracy and completeness of this data is crucial to optimizing traffic flow, improving road safety, and realizing autonomous driving.
[0003] At traffic intersections, especially in the waiting area, due to the large volume of traffic, complex traffic flow and interference from environmental factors, the data collected by sensors is often incomplete or erroneous.

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0019] First embodiment
[0020] The first embodiment of the present application relates to a method for repairing the heading angle of a vehicle in a waiting area. Figure 1 As shown, the method may include the following steps:
[0021] S101, caching high-precision map data to the cloud and obtaining real-time vehicle location data;
[0022] S102, judging whether the vehicle is in a waiting area according to the real-time position data of the vehicle and the high-precision map data;
[0023] S103: When the vehicle is in the waiting-to-turn area, the heading angle is repaired according to the difference between the heading angle of the vehicle and the heading angle of the lane to be turned:
[0024] If the difference is within a preset threshold range, the heading angle of the lane to be turned is used as the published heading;
[0025] If the difference exceeds a preset threshold range, the heading angle of the vehicle is used as the published heading.
[0026] The following is a detailed description of each of the above steps.
[0027] For step S101, high-precision map data is cached in the cloud to ensure that map data can be quickly acquired in real time, eliminating the limitations of local storage. Cloud processing has powerful computing and data storage capabilities, and can achieve multi-task concurrent processing, ensuring efficient response when facing large amounts of data. Acquiring real-time location data of the vehicle and combining it with high-precision maps can help accurately locate the vehicle, especially at complex intersections and waiting areas, effectively reducing the errors caused by traditional positioning methods.
[0028] For step S102, by comparing the real-time position data of the vehicle with the waiting area in the high-precision map, it is possible to accurately determine whether the vehicle has entered the waiting area. Compared with the method that relies solely on vehicle perception data, the road area where the vehicle is located can be more accurately determined by combining high-precision map data. Due to the complex traffic environment in the waiting area, the combination of high-precision maps and real-time data can reduce misjudgments caused by environmental factors (such as occlusion, reflection, etc.) and improve the ability to recognize the waiting state.
[0029] For step S103, when the vehicle is in the waiting-to-turn area, the heading angle is repaired according to the difference between the heading angle of the vehicle and the heading angle of the lane to be turned:
[0030] When the heading angle difference is within the preset range, the heading angle of the lane to be turned is used to correct the heading angle error reported by the vehicle. This method is particularly effective in the turning area, because the actual heading of the vehicle should be basically consistent with the lane direction. The corrected heading angle can provide more reliable data for traffic management systems and autonomous driving, improving the accuracy and safety of driving decisions.
[0031] When the heading angle difference exceeds the threshold, the vehicle's reported heading angle is retained to avoid errors caused by automatic repair. In this case, the original heading angle of the vehicle can be kept from being modified by mistake in abnormal situations, reducing the risk of wrong decisions.
[0032] It is not difficult to find that compared with related technologies, the solution provided in the embodiment of the present application can make full use of cloud computing resources and high-precision map data, effectively identify vehicles in the area to be turned, and intelligently correct the heading angle error, ensuring that the traffic management system and the autonomous driving vehicle obtain accurate and reliable vehicle position and heading information. This intelligent heading repair mechanism significantly improves the accuracy of the data, reduces misjudgment, and improves overall performance and safety.
[0033] Second embodiment
[0034] The second embodiment of the present application relates to a method for repairing the heading angle of a vehicle in a waiting area. The second implementation is an improvement made on the basis of the first embodiment, and the specific improvements are:
[0035] like Figure 2 As shown in the figure, in the intersection waiting area, the movement trajectory of the vehicle is relatively complex, and the vehicle's stagnation, slow driving, and change of direction will have a certain impact on the detection accuracy of roadside perception equipment (such as cameras, radars, lidars, etc.). Especially when the traffic volume is large, external factors such as occlusion between vehicles and changes in lighting conditions may further interfere with the detection of the equipment, resulting in errors or inaccuracies in the collected vehicle heading angle data.
[0036] In order to improve the accuracy and real-time performance of data processing, the system sends the location information and heading angle data collected by the roadside sensing device to the cloud processing platform through the data transmission module. The cloud platform is capable of processing large-scale, high-concurrency data streams and can quickly analyze real-time data from multiple roadside sensing devices. This processing capability is difficult to match with traditional local devices, and is especially suitable for intersections with complex traffic flows. By integrating and analyzing the data obtained by various types of roadside sensing devices (such as cameras, radars, lidars, etc.), the vehicle's motion trajectory and heading angle can be judged more accurately.
[0037] The cloud platform not only processes the real-time transmission of roadside perception data, but also can combine it with high-precision map data. High-precision maps provide accurate lane information, road geometry, and standard heading angles of the lanes to be turned in the area to be turned, which can more accurately repair and judge the heading angle. The data of various roadside perception devices can be fused and processed through the cloud platform to improve the accuracy of the data and reduce the impact of environmental interference on a single sensor. Combined with high-precision map data, the system can identify the current road environment and lane information of the vehicle, accurately determine whether the vehicle is in the area to be turned, and further repair the heading angle error.
[0038] Deploy the Storm program in the cloud to process roadside perception data. The Storm program has high concurrency processing and real-time data processing capabilities, and can effectively cope with the real-time processing needs of a large amount of sensor data. Cache high-precision map data in the cloud to ensure the real-time availability of map data. High-precision maps contain detailed information about the road, including lane lines, intersections, waiting areas, etc. Use high-precision map data and the real-time location data of the vehicle to determine whether the vehicle is in the waiting area. Compare the vehicle's GPS position with the waiting area in the high-precision map. If the vehicle is in the waiting area, mark the vehicle as waiting.
[0039] like Figure 3 As shown, the real-time location information of the vehicle is obtained (for example, through positioning devices such as GPS), and combined with high-precision map data to determine whether the vehicle is in the intersection area. If the vehicle is not in the intersection area, the heading angle is not repaired, and the lane heading of the road section is directly used as the published heading.
[0040] If the vehicle is at the intersection, it is further determined whether the vehicle is in the waiting area. The waiting area is usually located in front of the intersection, where the vehicle is waiting to turn under the control of the traffic light. The vehicle's GPS position is compared with the waiting area in the high-precision map data to make a judgment. If the vehicle is not in the waiting area, the vehicle's uploaded heading is used as the published heading.
[0041] When the vehicle is in the waiting area, the heading angle uploaded by the vehicle is obtained and compared with the standard lane heading angle of the waiting area recorded in the high-precision map to calculate the difference in heading angle. This difference is used to determine whether the vehicle's heading angle needs to be repaired. Usually a threshold is set (for example, 60 degrees), which can be configured and adjusted according to actual traffic conditions or system requirements.
[0042] If the difference is within the threshold range: When the difference between the vehicle's current heading angle and the standard heading angle of the lane to be turned is within the preset threshold range (for example, within 60 degrees), the vehicle's heading angle has a certain deviation. At this time, the heading angle of the lane to be turned is used as the published heading.
[0043] If the difference exceeds the threshold range: When the heading angle difference exceeds the preset threshold range, the vehicle's current state is considered to be inconsistent with expectations (for example, the vehicle deviates from the normal lane or an accident occurs). At this time, the heading angle reported by the vehicle is used as the published heading to avoid misjudgment.
[0044] According to the aforementioned repair logic, the vehicle's heading angle is finally determined and published to the relevant traffic management system or autonomous driving system to ensure that the vehicle can maintain the correct driving direction in a complex traffic environment.
[0045] Roadside sensing data is collected by roadside sensing equipment. When the accuracy of the heading angle of the vehicle in the turning area in the roadside sensing data is lower than a preset accuracy standard, the heading angle of the vehicle in the turning area is repaired.
[0046] It is not difficult to find that in the embodiment of the present application, the heading angle repair method based on the characteristics of the area to be turned can select the appropriate heading angle for repair according to the actual situation, avoiding the problem of misjudgment of heading in the traditional image perception and recognition method, and significantly improving the reliability of the vehicle heading angle data in the area to be turned. The architecture adopts a modular design, and the cloud processing platform, local perception equipment and data transmission module are relatively independent, which is convenient for the expansion and upgrading of the system and can adapt to the development of future technologies and changes in demand. Using cloud computing resources can reduce the demand for local computing equipment, reduce hardware costs, and improve cost-effectiveness by expanding computing resources on demand.
[0047] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
