Technical Field

[0001] The present invention relates to the field of data processing, and in particular to a method, device, storage medium and processor for processing road gantry position information. Background Art

[0002] With the development and expansion of the internet, some regions have begun eliminating provincial highway toll booths and implementing segmented toll collection and traffic statistics through the construction of smart highways. Highway gantries play a crucial role in segmented toll collection. To accurately implement segmented toll collection and traffic statistics for different roads, it's necessary to accurately restore the vehicle's road-level path, allowing for toll collection and calculation based on blocked roads.

[0003] However, with the continuous development of roads, there are now multiple routes from the starting point to the destination, and the lengths and tolls associated with each route vary. Therefore, more detailed gantry information is needed to accurately reconstruct the vehicle's actual route. However, in practice, due to a lack of basic infrastructure data and differences in measurement methods, problems such as missing gantry positions and large offsets often occur, introducing significant errors in vehicle trajectory reconstruction and road traffic statistics.

[0004] To address this issue, related technologies utilize data collection vehicles that drive to the gantry's location to collect data, combined with GPS data enhancement technology and data processing algorithms to obtain the gantry's location information. While this technology achieves high-precision gantry location information, it requires significant additional manpower and material resources, resulting in high costs and a long processing time.

[0029] Under the above operating environment, this application provides Figure 2 The method for processing the road gantry position information is shown. Figure 2 Flowchart of a method for processing road gantry position information according to an embodiment of the present invention, comprising:

[0030] S201, obtaining associated data of a road gantry, wherein the associated data includes at least: an identifier of the road gantry, a vehicle identifier corresponding to a vehicle passing through the road gantry, and a target time when the vehicle passes through the road gantry.

[0031] Specifically, the identification of the road gantry can be the ID of the road gantry, for example, gantry No. C on section B of road in city A. The vehicle identification can be the vehicle's license plate number. The vehicle identification corresponding to the vehicle passing through the road gantry can be the license plate number of the vehicle passed directly under the road gantry recorded by the gantry. The target time when the vehicle passes the road gantry can be the time when the license plate number of the vehicle passing through the road gantry is recorded. For example, the target road gantry records that the car with license plate number A passes directly under the target road gantry at 9:00, then the target time corresponding to vehicle A is 9:00.

[0032] S202, obtaining trajectory data of vehicles passing through multiple roads, wherein the trajectory data includes at least: a vehicle identification corresponding to each of the multiple roads passed by the vehicle, a road identification corresponding to each of the multiple roads passed by the vehicle, vehicle position information of the vehicle, and a time corresponding to each vehicle position information.

[0033] Specifically, the multiple roads can be all roads in a certain area, and the vehicle trajectory data can be obtained by GPS (Global Positioning System). For example, the vehicle trajectory data corresponding to all roads in area A is obtained, and the vehicle identification corresponding to the vehicle passing through each of the multiple roads can be the license plate number corresponding to the vehicle traveling on each road. The road identification corresponding to each road passed by each vehicle can be the road ID information corresponding to a vehicle when traveling on multiple roads. The vehicle position information of the vehicle can be the position information obtained according to GPS during the vehicle's driving process, and the time corresponding to the vehicle position information is the time corresponding to the acquisition of the vehicle position information.

[0034] For example, if car A travels on three roads in area A, the license plate number of car A corresponds to the road IDs of the three roads. During the driving process of car A, the GPS of car A records the driving data and the time point corresponding to each driving position according to a preset time period. For example, the latitude and longitude of the vehicle at 9:01 is (A, B), and at 9:02, the latitude and longitude of the vehicle is (C, D).

[0035] In order to establish an association between a vehicle identification and a road identification on which the vehicle has traveled, optionally, in the method for processing road gantry position information in an embodiment of the present invention, before obtaining trajectory data of vehicles passing through multiple roads, the method further includes: obtaining road topology information, wherein the road topology information includes at least: road identifications of multiple roads and location information of each road; obtaining vehicle trajectory information, wherein the vehicle trajectory information includes the vehicle identification, the vehicle location information of the vehicle and the time corresponding to each vehicle location information; matching the road topology information and the vehicle trajectory information according to the location information of each road and the vehicle location information of the vehicle to obtain trajectory data of vehicles on multiple roads.

[0036] Specifically, the road topology information can be the topology information obtained by correlating all roads in a certain area, which may include: the road sign of each road and the location information of each road; the vehicle trajectory information can be the driving route information of each vehicle and the location information recorded by GPS and the time corresponding to each location information.

[0037] It should be noted that the vehicle's route can be matched based on the road's location information and the vehicle's GPS location information. If the road's location information and the vehicle's GPS location information overlap, it can be determined that the vehicle is traveling on that road. In this case, the road ID of that road can be matched with the vehicle to obtain vehicle trajectory data for multiple roads. For example, the vehicle's GPS data can be matched based on road topology information. After a successful match, the vehicle's trajectory can be mapped to the corresponding road to obtain the vehicle's precise trajectory for all sections of the road topology network.

[0038] In order to establish topological information between multiple roads, optionally, in the method for processing road gantry position information of an embodiment of the present invention, before obtaining the road topological information, the method also includes: obtaining the road signs and road location information corresponding to each of the multiple roads, and constructing the topological relationship between the multiple roads based on the road location information to obtain the road topological information.

[0039] Specifically, each road has fixed road signs and road location information, that is, basic road information. The relative position relationship between each road can be determined based on the basic road information, thereby constructing the topological relationship between all roads and generating road topology information. The road topology information can characterize the accessibility between roads.

[0040] For example, there are 5 roads in area A. The accessibility and position relationship between the 5 roads can be determined by the starting point location, end point location, and longitude and latitude of each road, thereby obtaining the road topology information.

[0041] S203, determining the target vehicle position information and the time corresponding to the target vehicle position information based on the associated data and the trajectory data, wherein the target vehicle position information is the vehicle position information when each vehicle passes through the road gantry.

[0042] Specifically, the target vehicle position information can be the position information corresponding to when the vehicle passes before and after the road gantry, and the moment corresponding to the target vehicle position information can be the moment before and after the vehicle passes before and after the road gantry. The target vehicle position information of the vehicle and the moment corresponding to the target vehicle position information can be obtained from the vehicle position information of the vehicle and the moment corresponding to the vehicle position information.

[0043] It should be noted that since there is an association between vehicle identification and road identification, the road information corresponding to the road gantry can be determined when the vehicle passes through the road gantry, thereby obtaining the position information of the road gantry and the road information of the road gantry based on the target vehicle position information and the road identification.

[0044] In order to accurately determine the position information of the road gantry through the target vehicle position information. Optionally, in the method for processing the road gantry position information of an embodiment of the present invention, determining the target vehicle position information and the time corresponding to the target vehicle position information based on the associated data and the trajectory data includes: obtaining the trajectory data of the vehicle passing through the road gantry from the trajectory data according to the vehicle identification to obtain a plurality of target trajectory data; determining the previous moment adjacent to the target moment from the time corresponding to the vehicle position information in each target trajectory data to obtain a first moment, and determining the next moment adjacent to the target moment to obtain a second moment, and determining the time corresponding to the target vehicle position information based on the first moment and the second moment; determining the first position information corresponding to the first moment, determining the second position information corresponding to the second moment, and determining the target vehicle position information based on the first position information and the second position information.

[0045] Specifically, since the trajectory data includes the trajectory data of all vehicles, it is necessary to obtain the trajectory data of the vehicles passing through the target road gantry from the trajectory data according to the license plate identification corresponding to the target road gantry, thereby obtaining a plurality of target trajectory data.

[0046] Furthermore, the target moment when the vehicle passes the target road gantry is obtained, and the target moment is substituted into the multiple trajectory data, so as to match the previous moment and the next moment adjacent to the target moment from the moment corresponding to the vehicle position information to obtain the first moment and the second moment.

[0047] For example, in the associated data of road gantry A, the target time for vehicle A to pass through the road gantry is 8:00. Then 8:00 can be substituted into the trajectory data corresponding to vehicle A, so that the time before 8:00:00 can be determined in the time corresponding to the vehicle position information of vehicle A to be 7:59:30, and the time after 8:00:00 can be 8:00:30, thereby obtaining the first time and second time corresponding to vehicle A.

[0048] It should be noted that after obtaining the first moment and the second moment, the first position information corresponding to the vehicle at the first moment and the second position information corresponding to the vehicle at the second moment can be obtained according to the corresponding relationship, and the first position information and the second position information can be determined as the target vehicle position information, and the position information of the target road gantry can be determined according to the target vehicle position information and the moment corresponding to the target vehicle position information.

[0049] S204, determining the target position information of the road gantry according to the target vehicle position information, the time corresponding to the target vehicle position information, and the target time.

[0050] Specifically, after obtaining the target vehicle position information, the time corresponding to the target vehicle position information and the target time, the speed of the vehicle when passing the target road gantry can be calculated based on the relationship between the target time and the time corresponding to the target vehicle position information and the target vehicle position information, and the position information of the target road gantry can be calculated based on the speed information and the target time.

[0051] In order to improve the accuracy of calculating the position information of the road gantry, optionally, in the method for processing the position information of the road gantry in an embodiment of the present invention, the target position information of the road gantry is determined based on the target vehicle position information, the time corresponding to the target vehicle position information and the target time, including: calculating the initial position information of the road gantry based on the target vehicle position information, the time corresponding to the target vehicle position information and the target time to obtain multiple initial position information; and determining the target position information of the road gantry through the multiple initial position information.

[0052] Specifically, the initial position information is the gantry's position information calculated using the target vehicle position information corresponding to each vehicle, the time corresponding to the target vehicle position information, and the target time. The initial position information corresponding to a certain number of vehicles can be selected to calculate the accurate gantry position information, i.e., the target position information, based on the distribution of the initial position information.

[0053] In order to accurately calculate the initial position information corresponding to each vehicle, optionally, in the method for processing the road gantry position information of an embodiment of the present invention, calculating the initial position information of the road gantry based on the target vehicle position information, the moment corresponding to the target vehicle position information and the target moment includes: determining a first time difference between the first moment and the second moment, and determining a distance difference between the first position information and the second position information; calculating the speed of the vehicle when passing through the road gantry based on the distance difference and the first time difference; determining a second time difference between the target moment and the first moment, and calculating the initial position information of the road gantry based on the speed and the second time difference.

[0054] The speed of the vehicle as it passes the road gantry can be calculated based on the target vehicle position information and the time corresponding to the target vehicle position information. Specifically, a first time difference between a first time and a second time can be determined, and a distance difference between the first position information and the second position information can be determined. The distance difference is divided by the first time difference to obtain an average speed. The distance between the first position information and the road gantry can be calculated based on the second time difference between the target time and the first time. Thus, the initial position information of the road gantry can be calculated based on the first position information and the distance between the first position information and the road gantry.

[0055] For example, the first moment can be 8:30:00, the second moment can be 8:31:00, the target moment can be 8:30:30, the first position information can be (1, 1), and the second position information can be (3, 1). The speed can be calculated as 2 / 1=2m / s, and the interval between the road gantry and the first position can be determined to be 1 meter based on the time difference between the first moment and the target moment. The initial position information of the road gantry can be determined to be (2, 1).

[0056] In order to make the position information of the road gantry more accurate, optionally, in the method for processing the position information of the road gantry in an embodiment of the present invention, determining the target position information of the road gantry through multiple initial position information includes: sorting the multiple initial position information to obtain a sorting result; obtaining the median in the sorting result, and determining the initial position information corresponding to the median as the target position information of the road gantry; or, calculating the average value of the multiple initial position information, and determining the average value as the target position information of the road gantry.

[0057] Specifically, there may be errors in the initial position information. After calculating multiple initial position information corresponding to the road gantry based on the target vehicle position information of multiple vehicles, the median or average of the multiple initial position information can be calculated, and the average or median can be used as the target position information of the road gantry, thereby achieving the effect of conveniently and accurately calculating the position information of the road gantry.

[0058] Optionally, in the method for processing the road gantry position information of an embodiment of the present invention, obtaining the associated data of the road gantry includes: obtaining the identification of the road gantry, obtaining the vehicle identification corresponding to the vehicles passing through the road gantry within a preset time period, and the target time when the vehicle passes through the road gantry; or, obtaining the identification of the road gantry, obtaining the vehicle identification corresponding to the target vehicle passing through the road gantry, and the target time when the target vehicle passes through the road gantry, wherein the target vehicles are multiple vehicles traveling at a preset speed.

[0059] Specifically, when acquiring data associated with a road gantry, information about vehicles passing through the gantry during a preset time period can be obtained. This preset time period can be peak traffic hours. This allows for the acquisition of a large amount of associated data, thereby improving the accuracy of calculating the gantry's position. Alternatively, a certain number of vehicles can be dispatched to pass through the gantry at a specific speed and their data recorded, thereby improving the accuracy of calculating the gantry's position.

[0060] In an embodiment of the present invention, the association data of a road gantry is obtained, wherein the association data includes at least: an identification of the road gantry, a vehicle identification corresponding to a vehicle passing through the road gantry, and a target time when the vehicle passes through the road gantry; the trajectory data of a vehicle passing through multiple roads is obtained, wherein the trajectory data includes at least: a vehicle identification corresponding to a vehicle passing through each of the multiple roads, a road identification corresponding to a road passed by each vehicle, vehicle position information of the vehicle and a time corresponding to each vehicle position information; the target vehicle position information and the time corresponding to the target vehicle position information are determined based on the association data and the trajectory data, wherein the target vehicle position information is The vehicle position information of each vehicle when passing through the road gantry; a method of determining the target position information of the road gantry based on the target vehicle position information, the time corresponding to the target vehicle position information and the target time, by obtaining the associated data of the road gantry and the trajectory data of vehicles passing through multiple roads, and making the two types of data correspond in time and space according to the vehicle identification in the data, so that the position information of the gantry and the road information corresponding to the gantry can be determined according to the position information and road information of the vehicle when passing through the gantry, thereby achieving the purpose of efficiently and accurately determining the position information of the road gantry, and thus solving the technical problem of high cost and low efficiency of the method for determining the position information of the road gantry in the related art.

[0061] It should be noted that for the aforementioned method embodiments, for simplicity of description, they are all expressed as a series of action combinations. However, those skilled in the art should be aware that the present invention is not limited by the order of the actions described, because according to the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.

[0062] Through the description of the above embodiments, those skilled in the art can clearly understand that the method for processing the road gantry position information according to the above embodiment can be implemented by means of software plus a necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product. The computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0064] According to an embodiment of the present invention, a flowchart of an optional method for processing road gantry position information is also provided. Figure 3is a flow chart of an optional method for processing road gantry position information according to an embodiment of the present invention. Figure 3 As shown:

[0065] First, road information of multiple roads is obtained, wherein the road information includes road ID (road identification) and road location, and the road information is topologically related according to the road location to obtain road topology information of multiple roads, wherein the road topology information includes the road ID and road location of each road.

[0066] Furthermore, vehicle trajectory information is obtained, where the vehicle trajectory information includes: vehicle ID, GPS location, and the time corresponding to each location. In this case, the trajectory data of each vehicle can be obtained using the GPS location information and the road location information, where the trajectory data includes the vehicle ID, road ID, vehicle GPS location, and the time corresponding to each location.

[0067] Furthermore, it is also necessary to obtain the associated data of the road gantry, including the ID of the road gantry, the vehicle identification corresponding to the vehicle passing through the road gantry, and the target time when the vehicle passes through the road gantry, and the trajectory data and the associated data are spatially and temporally collided through the vehicle ID and time information to obtain the vehicle ID, road gantry ID, the target time when the vehicle passes through the gantry, the road ID corresponding to when the vehicle passes through the gantry, the target vehicle position information when the vehicle passes through the gantry, and the time corresponding to the target vehicle position information, and determine the initial position information through the time corresponding to the target vehicle position information and the target time, including: vehicle ID, gantry ID, road ID of the road to which the gantry belongs, and the initial position information of the road gantry.

[0068] Finally, the gantry information of the road gantry is calculated through multiple initial position information, including: the gantry ID, the road ID of the road to which the gantry belongs and the target position information of the gantry, thereby completing the determination of the gantry position information.

[0069] This embodiment performs analysis and statistics based on existing basic road information, road gantry association information and vehicle trajectory information to obtain corrected road gantry position information, thereby improving the efficiency of obtaining road gantry position information, reducing the acquisition cost, and meeting the accuracy requirements of the gantry position information.
