The specific embodiment of the present invention applied to the device is substantially the same as the following embodiments of the present invention applied to the method for querying vehicles in the same lane, and will not be described herein again.
The embodiment of the invention provides a method for inquiring vehicles in the same driving, and referring to fig. 2, fig. 2 is a schematic flow chart of the embodiment of the method for inquiring vehicles in the same driving.
In this embodiment, the method for querying vehicles in the same traveling includes the following steps:
and S100, determining a same-trip time period according to the time information of the target vehicle passing through the target position.
Specifically, in the present embodiment, the same-trip time period is determined based on 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 detection means provided at the target position; and acquiring an initial same-row error, and determining a same-row time period based on the passing time point and the initial same-row error.
The range expression of the same-row time period specifically includes: [ t-t1, t + t1], t is a passing time point, and t1 is an initial in-line 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 same row in this embodiment. For the behavior of intentionally avoiding the peer detection, for example, a mode of successively passing through the target position, the embodiment adopts a mode of considering the peer error and the peer time period, and provides more comprehensive data support for the query of the peer vehicle.
And S200, acquiring 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 acquired, 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 acquiring the monitoring video of the target position in the same-row time period; matching the monitoring video of the vehicle corresponding to the identification information in a city monitoring database according to the identification information; 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 videos of each vehicle after passing through the target position, the embodiment can match the extracted vehicle identification with the monitoring videos of the corresponding vehicle in the city monitoring database by acquiring the monitoring videos of the target position and the rest positions after the same-row time period in the same-row time period, and then generate the path information of each vehicle according to the monitoring videos.
Therefore, before the step of matching the path information of each vehicle according to the identification information is executed, the embodiment further 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. Therefore, when the path information of each vehicle is generated, the path information of each vehicle can be generated based on the identification information and the video position information corresponding to the monitoring video.
And step S300, judging whether the path information of the other vehicles meets the path information of the vehicle concurrent running requirement with the path information of the target vehicle.
Specifically, in the present embodiment, it is determined whether or not there is route information that satisfies the vehicle co-traveling requirement with the route information of the target vehicle among the route information of the remaining vehicles, by determining: (1) And generating path coincidence ratios 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 position of the target vehicle and the end positions of the other vehicles according to the end positions. (3) And judging whether the path information of the target vehicle meets the path information of the vehicle in-line requirements or not in the path information of the other vehicles according to the vehicle in-line coefficient and a preset in-line coefficient.
It should be noted that, in this embodiment, a vehicle co-traveling coefficient is generated according to the path coincidence ratio of the target vehicle and the other vehicles and the relative distance between the end point position of the target vehicle and the end point positions of the other vehicles, and finally, the vehicle co-traveling coefficient and the preset communication coefficient are determined, so that independent co-traveling determination can be performed on each of the other vehicles and the target vehicle passing through the target position in the co-traveling time period.
In practical application, the path overlapping ratio and the vehicle co-running coefficient should be in direct proportion, and the relative distance of the end point position should be in inverse proportion. In addition, there are some special conditions such as a case where the peer detection is intentionally avoided by way of a halfway detour, in which a peer policy occurs in which the distance of the end position is close but the path overlapping ratio is low. Therefore, it is also necessary to consider adjustment of the co-traveling coefficient of the vehicle in which the end position distance is close and the path overlapping ratio is low.
Specifically, the expression of the vehicle co-traveling coefficient is specifically:
wherein s is the co-traveling coefficient of the vehicle, r is the path coincidence ratio, x is the relative distance of the terminal position, and r 0 For a predetermined path-coincidence ratio, x 0 Setting a relative distance of a preset end point position;
therefore, in this embodiment, the expression that satisfies the requirement of the same vehicle row is specifically:
s≥s 0 ×k
wherein s is 0 The method comprises the steps that a preset co-traveling coefficient is set, the preset co-traveling coefficient is an average value of historical co-traveling coefficients corresponding to path information of a target vehicle, and k is a constant.
In this embodiment, when the vehicle co-traveling coefficient is not less than k times of the preset communication coefficient, it can be determined that the vehicle co-traveling requirement is satisfied.
Step S400, if yes, outputting the vehicle corresponding to the path information meeting the vehicle co-traveling requirement as the co-traveling vehicle of the target vehicle; if not, adjusting the same-trip time period, and returning to execute the step of obtaining the identification information of the other vehicles passing through the target position in the same-trip time period.
Specifically, according to the obtained vehicle co-traveling coefficient and the preset co-traveling coefficient, whether the target vehicle and the rest of the corresponding vehicles are passing vehicles can be judged.
It should be noted that if a co-running vehicle is queried in a co-running time period, it may happen that the co-running detection is intentionally avoided by using a target position at different times before and after the co-running vehicle, and the time before and after the co-running vehicle exceeds an initial co-running error, the previous co-running time period needs to be readjusted.
In practical application, the adjustment of the same-row time period is carried out again, the step of obtaining the identification information of other vehicles passing through the target position in the passing time period is returned and executed by increasing the initial same-row error, and the query is stopped until the same-row vehicles of the target vehicle are output or the difference value between the average value of the vehicle same-row coefficients of the target vehicle and each of the other vehicles and the preset same-row coefficient is smaller than the preset value.
In this embodiment, a situation that the target vehicle does not travel with the same-traveling vehicle may also occur, and at this time, the query needs to be stopped in time. It should be noted that, as the time period of the same-row increases, the average value of the vehicle co-row coefficients of the target vehicle and the other vehicles in the time period of the same-row gradually approaches to the preset co-row coefficient (i.e., the average value of the historical co-row coefficients), so that when the query is stopped, the average value of the vehicle co-row coefficients of the target vehicle and the other vehicles in the current time period of the same-row may be obtained through calculation, and if the average value approaches to the preset co-row coefficient and the difference value is smaller than the preset value, it may be determined that the average value approaches to the preset co-row coefficient very much, that is, it is determined that the target vehicle does not travel the same-row vehicle.
In this embodiment, a method for querying a co-traveling vehicle is provided, where a co-traveling time period is gradually adjusted to obtain path information of a vehicle in the co-traveling time period, so as to determine whether the vehicle is a co-traveling vehicle, thereby solving a technical problem that detection and query of the co-traveling vehicle are easily and intentionally avoided at present.
