It will be appreciated by those skilled in the art that the arrangement of the apparatus shown in fig. 1 is not limiting and may include more or fewer components than shown, or certain components may be combined, or a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and a peer-to-peer vehicle inquiry program may be included in the memory 1005, which is a type of computer storage medium.

The specific embodiment of the present invention applied to the device is basically the same as each embodiment of the following method for querying the same-vehicle, and will not be described herein.
The embodiment of the invention provides a method for inquiring vehicles on the same road, and referring to fig. 2, fig. 2 is a schematic flow chart of the embodiment of the method for inquiring vehicles on the same road.
In this embodiment, the method for inquiring the vehicles on the same road includes the following steps:
step S100, determining the same-line time period according to the time information of the target vehicle passing through the target position.
Specifically, in the present embodiment, the same-row period is determined according to the time information of the target vehicle passing through the target position, and the passing time point of the target vehicle is determined when the target vehicle passing through the target position is detected by the target vehicle detecting device provided at the target position; and acquiring an initial peer error, and determining a peer time period based on the passing time point and the initial peer error.
The range expression of the same-row time period specifically includes: [ t-t1, t+t1], t is the passage time point, and t1 is the initial same-row error.
It should be noted that, the target position may be used as an initial position for determining whether the target vehicle and the vehicle in the same row are in the present embodiment. For the behavior of intentionally avoiding the detection of the same line, for example, in a mode of passing through the target position successively, the method of considering the error of the same line and the time period of the same line is adopted in the embodiment, so that more comprehensive data support is provided for the query of the vehicles of the same line.
Step S200, obtaining the identification information of all vehicles passing through the target position in the same-row time period, and matching the path information of each vehicle according to the identification information.
Specifically, in this embodiment, identification information of all vehicles passing through a target position in a same-row time period is obtained, path information of each vehicle is matched according to the identification information, and identification information of all vehicles passing through the target position is extracted from a monitoring video by obtaining the monitoring video of the target position in the same-row time period; according to the identification information, matching a monitoring video of the vehicle corresponding to the identification information in a city monitoring database; and generating path information of each vehicle based on the monitoring video.
It should be noted that, on the basis that the city monitoring system collects the monitoring video of each vehicle after passing through the target position, the embodiment can match the extracted vehicle identifier with the monitoring video of the corresponding vehicle in the city monitoring database by obtaining the monitoring video of the target position in the same-row time period and the rest positions after the same-row time period, and then generate the path information of each vehicle according to the monitoring video.
Therefore, before executing the step of matching the path information of each vehicle according to the identification information, the embodiment also needs to acquire the monitoring video and the video position information stored in the city monitoring database, identify the identification information of the vehicle in the monitoring video, and mark the monitoring video by using the identification information and the video position information. Thus, when generating the path information of each vehicle, the path information of each vehicle can be generated based on the identification information and the video position information corresponding to the monitoring video.
Step S300, determining whether there is path information satisfying the requirement of the same vehicle as the path information of the target vehicle in the path information of the rest vehicles.
Specifically, in the present embodiment, it is determined whether or not there is path information satisfying the vehicle-same requirement as the path information of the target vehicle among the path information in the remaining vehicles, by determining: (1) And generating a path superposition ratio of the target vehicle and the rest vehicles according to the path information of all the vehicles. (2) And extracting the end positions in the path information of all the vehicles, and generating the relative distance between the end positions of the target vehicles and the end positions of the other vehicles according to the end positions. (3) And judging whether path information meeting the requirement of the same vehicle as the path information of the target vehicle exists in the path information of the other vehicles according to the same vehicle coefficient and a preset same vehicle coefficient.
In this embodiment, the vehicle identical coefficient is generated by the path overlapping ratio of the target vehicle and the rest vehicles and the relative distance between the end position of the target vehicle and the end position of the rest vehicles, and finally the vehicle identical coefficient and the preset communication coefficient are judged, so that independent identical judgment can be performed on each rest vehicle passing through the target position in the identical time period and the target vehicle.
In practical application, the path coincidence ratio and the vehicle same-line coefficient should be in direct proportion, and the relative distance of the end point position should be in inverse proportion. In addition, there are special conditions, such as a case of deliberately avoiding the detection of the same line by midway detour, in which case a same line policy with a very close distance of the end position but a very low path overlap ratio occurs. Therefore, it is also necessary to consider the adjustment of the vehicle co-operation coefficient in which the end position distance is very short and the path overlap ratio is very low.
Specifically, the expression of the vehicle co-operation coefficient is specifically:
wherein s is the same-line coefficient of the vehicles, r is the path coincidence ratio, x is the relative distance of the end position, r 0 For presetting the path coincidence ratio, x 0 The relative distance is the preset end position;
thus, in this embodiment, the expression that satisfies the requirement of the same vehicle is specifically:
s≥s 0 ×k
wherein s is 0 The method comprises the steps that the preset same-line coefficient is a preset average value of historical same-line coefficients corresponding to path information of a target vehicle, and k is a constant.
In this embodiment, when the vehicle-to-line coefficient is not less than k times the preset communication coefficient, it is determined that the vehicle-to-line requirement is satisfied.
Step S400, if yes, outputting the vehicles corresponding to the path information meeting the vehicle co-traveling requirements as the co-traveling vehicles of the target vehicles; if not, the same-row time period is adjusted, and the step of acquiring the identification information of the rest vehicles passing through the target position in the same-row time period is carried out.
Specifically, according to the obtained vehicle co-running coefficient and the preset co-running coefficient, whether the target vehicle and the other corresponding vehicles are passing vehicles or not can be judged.
It should be noted that if the peer vehicles are queried in the peer time period, the peer detection may be intentionally avoided by the target position with different front and rear times, and the front and rear times exceed the initial peer error, and the previous peer time period needs to be readjusted.
In practical application, readjustment of the same-line time period is performed, by increasing the initial same-line error, the step of obtaining the identification information of the other vehicles passing through the target position in the passing time period is performed in a returning mode until the same-line vehicles of the target vehicle are output or the difference value between the average value of the vehicle same-line coefficients of the target vehicle and the other vehicles and the preset same-line coefficient is smaller than a preset value, and inquiry is stopped.
In this embodiment, the situation that the target vehicle travels without the same-vehicle may also occur, and at this time, the inquiry needs to be stopped in time. It should be noted that, as the period of the same-line time increases, the average value of the vehicle co-line coefficients of the target vehicle and the other vehicles in the period of the same-line time gradually approaches to the preset co-line coefficient (i.e., the average value of the historical co-line coefficients), so that when the judgment of the inquiry is stopped, the average value of the vehicle co-line coefficients of the target vehicle and the other vehicles in the current period of the same-line time can be obtained through calculation, if the average value approaches to the preset co-line coefficient and the difference value is smaller than the preset value, the average value can be considered to be very close to the preset co-line coefficient, that is, the target vehicle is judged to travel without the same-line vehicle.
In this embodiment, a method for querying vehicles in the same row is provided, and path information of vehicles in the same row time period is obtained by gradually adjusting the same row time period, so as to determine whether the vehicles are vehicles in the same row, thereby solving the technical problem that the detection and query of the current vehicles in the same row are easy to be intentionally avoided.
Referring to fig. 3, fig. 3 is a block diagram illustrating a construction of an embodiment of a query device for a peer-to-peer vehicle according to the present invention.
