FIG. 1 is a schematic diagram of some embodiments of an anomalous vehicle identification method of the present disclosure. Preferably, the present embodiment may be executed by an abnormal vehicle recognition apparatus. The method comprises the following steps:
and 11, acquiring a monitoring index of the vehicle to be detected.
In some embodiments of the present disclosure, the obtaining of the monitoring index of the vehicle to be tested may include: and determining the travel of the vehicle to be tested and the monitoring index of the vehicle to be tested according to the traffic information of the vehicle gate to be tested.
The passing information of the vehicle gate to be detected comprises at least one of gate codes, gate passing time and passing vehicle information of the gate.
In some embodiments of the present disclosure, the traffic information of the vehicle to be tested may include camera data provided at a traffic light of a gate.
In some embodiments of the present disclosure, the vehicle monitoring index to be measured includes at least one of a travel code, a travel time period, a transit time, a number of passing gates, vehicle travel data of vehicles passing through the same travel in a predetermined period, and vehicle travel data of vehicles passing through the same travel in the predetermined period and the same travel time period.
In some embodiments of the present disclosure, the determining the vehicle travel and the vehicle monitoring index according to the vehicle entrance traffic information to be measured includes: through carrying out preprocessing on the passing information of the gate, calculating a travel code and a monitoring index of the waiting-to-be-detected vehicle in a travel time period, and restoring a travel route of the vehicle.
In some embodiments of the present disclosure, the step of determining a monitoring index of the journey code waiting vehicle according to the gate traffic information may include:
step 11, it is assumed that the original bayonet traffic information data includes three adjacent lines of data as shown in table 1:
TABLE 1
Bayonet numbering Passage time of gate License plate for passing through bayonet
001 intersection 22/2/2019 License plate number A0001
002 crossing Year 2019, month 2, 23, day 5 License plate number A0001
003 crossing Year 2019, month 2, 23, day 10 License plate number A0001
And 12, calculating the time interval distribution between two gates according to the data of the vehicles passing through the gates, wherein an obvious time interval layer is required to be arranged between two adjacent intersections. From the 001 intersection to the 002 intersection, the vehicle takes a period of time divided into 3 hours and 10 hours (with a 7-hour break in between). Then, the vehicle that reaches the 002 intersection from the intersection 001 within 3 hours is described, and the 002 intersection is the gate through which the vehicle passes. The vehicle that passes through after 10 hours, which means that the 002 crossing is the first crossing (departure point) that it starts to pass through. The 001 intersection is the destination (end point) of the previous trip, that is, the vehicle returns to home after passing through the last gate in 2 months, 22 days, 30 days, the 001 intersection is the end point, and the 2 months, 23 days, the vehicle starts from home, reaches the first intersection 002 of the current trip at 5.
Step 13, a series of records connecting the starting point and the ending point are combined into a journey, and the journey comprises a departure point, an end point, a temporary trip, temporary trip time and the like, and subsequent journey costs, the number of journey passing temporary trips and the like are processed according to the table 1.
Step 14, adding a tolerance value to the duration of the discontinuous layer when the two intersections occur as a standard value of the slicing stroke, in this example, 3 hours +3 hours × 1.5=4.5 hours, if the vehicle from the intersection 001 to the intersection 002 exceeds 4.5 hours, 001 is the end point of the forward stroke, and 002 is the start point of the next stroke. If the time does not exceed 4.5 hours, the time is 002 the passing point of the stroke, and the stroke end needs to be continuously found.
In some embodiments of the present disclosure, the step of determining a monitoring index of the journey code waiting vehicle according to the gate traffic information may include: and determining the trip time period of the vehicle to be tested according to the passing information of the gate.
In some embodiments of the present disclosure, because the vehicle has peak value change of peak value in the morning and evening, whether the time spent between all two checkpoints is reasonable can be determined as abnormal, and the time needs to be considered in combination with the travel period.
And the travel time period is divided according to the vehicle peak value change in 24 hours in the city. Based on the following two principles:
first, the travel time period cannot be set too narrow, for example, a 24-hour day is divided into a time period 1-24, and in the time period 1, if only 3 vehicles pass through from the intersection a to the intersection B, respectively 20 minutes 30 minutes and 31 minutes, a sample is insufficient, and the 20-minute vehicle cannot be an abnormal vehicle with a large time difference from most of the vehicles in terms of variance,
Secondly, the trip time period cannot be set too long, and if the trip time period is set too long, the two peak time periods are wrapped, so that the identification accuracy of the abnormal vehicle is insufficient.
Therefore, in some embodiments of the present disclosure, the travel time period may be set to 3-5 time periods in 24 hours a day according to the morning and evening peaks and the morning and valley of the local city.
The method comprises the steps of identifying abnormal characteristics of each vehicle from a starting place to a shooting point at the moment of shooting by a camera, calculating abnormal values, determining where the vehicle comes from, where the vehicle goes to, what route the vehicle goes along, how much the vehicle drives, and identifying and marking suspicious points through sensitive places and other full-period characteristics.
And step 12, judging whether the vehicle to be detected is an abnormal vehicle or not according to the vehicle monitoring index to be detected.
In some embodiments of the present disclosure, the abnormal vehicle may be a vehicle involved in a case, such as a vehicle involved in a virus.
In some embodiments of the present disclosure, step 12 may comprise:
and step 121, determining a route (key route) of the to-be-detected vehicle according to the to-be-detected vehicle route code.
In some embodiments of the present disclosure, step 121 may comprise: firstly, the travel routes are grouped, and the route numbers with more cases (for example, more virus-related) are found to be used as the travel routes to be detected.
And step 122, judging whether the vehicle to be detected is an abnormal vehicle or not according to the vehicle to be detected monitoring index aiming at the vehicle to be detected with the stroke code as the stroke route to be detected.
Based on the abnormal vehicle identification method provided by the embodiment of the disclosure, on the premise that a case clerk does not receive any clues and does not know the occurrence of a case, the system can automatically identify the abnormal behavior vehicle according to the monitoring data and warn the vehicle possibly involved in the case, namely, the output without input can be realized.
FIG. 2 is a schematic illustration of further embodiments of the disclosed abnormal vehicle identification method. Preferably, the present embodiment may be executed by an abnormal vehicle recognition apparatus. The method (for example, the step of determining whether the vehicle to be tested is an abnormal vehicle according to the vehicle monitoring index in step 12 or step 122 in the embodiment of fig. 1) may include the following steps 21 to 23, where:
and step 21, judging whether the vehicle to be detected has the abnormal vehicle track condition according to the monitoring index of the vehicle to be detected.
In some embodiments of the present disclosure, step 21 may comprise: and inputting the monitoring index of the vehicle to be detected into the vehicle track abnormity model to obtain the vehicle track abnormity condition.
In some embodiments of the present disclosure, step 21 may comprise: correctly identifying a travel plan; and analyzing a series of checkpoints passed by the trip plan, including traffic speed analysis, communication starting point and destination analysis, trajectory topological structure analysis and the like.
FIG. 3 is a schematic diagram of an abnormal vehicle trajectory identification model in some embodiments of the present disclosure. The abnormal vehicle track identification model is used for judging whether the vehicle to be detected is an abnormal vehicle or not according to the vehicle monitoring index to be detected. As shown in fig. 3, the abnormal vehicle trajectory recognition model may include at least one of a vehicle trajectory abnormality model, a vehicle travel abnormality model, and an abnormal vehicle recognition model.
In some embodiments of the present disclosure, as shown in fig. 3, the abnormal vehicle track condition includes at least one of an abnormal vehicle speed (stop and pause), an abnormal vehicle passing through the gate (circle winding), and an abnormal vehicle passing time (abrasion and rub).
In some embodiments of the present disclosure, step 21 may identify an abnormal condition of abnormal vehicle speed (stop and pause), and the vehicle trajectory abnormality model in fig. 3 may be used to identify an abnormal condition of abnormal vehicle speed (stop and pause). At this time, step 21 may include:
and step 211, setting a plurality of passing standard time intervals passing through each gate for each gate according to the passing time of the passing vehicle passing through each gate in the same trip time period.
In some embodiments of the present disclosure, step 211 may include: and setting a bayonet passing cost table. Sequencing the passing time of the passing vehicles in the same time segment aiming at the vehicle route gate A and the next gate B thereof; the time spent on the 1/10 median is recorded as T1, the time spent on the 2/10 median is recorded as T2, and so on, and 9 reference values (T1, \8230;, T9) of the time spent on the crossing of the bayonet are obtained in turn.
And 212, comparing the passing time of the vehicle to be detected passing through each gate in the travel with a plurality of passing standard time intervals passing through the gate, and determining the passing cost of the vehicle to be detected passing through each gate, wherein the passing cost of the vehicle to be detected passing through each gate corresponds to the passing standard time interval of the communication time of the vehicle to be detected passing through each gate.
FIG. 4 is a schematic diagram of a normal vehicle bayonet travel cost table in some embodiments of the present disclosure. Fig. 5 is a schematic diagram of a card gate passing cost table of an abnormal vehicle (involved vehicle) in some embodiments of the disclosure.
In fig. 4, lines 1-7 are strokes 1 and lines 8-12 are strokes 2. Lines 1-11 in fig. 5 represent the 3 rd stroke. Each row in fig. 4 and 5 represents 9 reference values (T1, \8230;, T9) for a vehicle to pass through a gate, wherein the darker one is the transit time of the vehicle to be tested for the current trip through the gate. And determining the passing cost of the vehicle to be tested in the journey through the gate according to a reference value (T1, \8230; T9) corresponding to the passing time of the vehicle to be tested in the journey through the gate. For example: in fig. 4, lines 1-6 are the passing costs of the vehicle to be tested passing through the 1 st to 6 th bayonets in the 1 st journey, which are respectively (1, 2, 1).
And step 213, determining the stability of the running cost of the vehicle to be detected in the travel according to the mathematical variance.
And 214, determining whether the vehicle to be detected in the travel has abnormal vehicle speed according to the stability degree of the passing cost of the vehicle to be detected in the travel.
For the vehicle to be tested in the embodiment of fig. 4, the passing time of each gate is on the left side of the median, and the vehicle speed is stable; the vehicle is in a driving state without any contraindication, and therefore the vehicle to be tested in fig. 4 is a normal vehicle.
For the vehicle under test of the embodiment of fig. 5, on the same road segment, it is faster than most people to drive; the performance is very unstable after a while and slower than that of most people; is a driving state with concern; the system can be opened quickly, but the external environment needs to be observed by taking care. Therefore, the vehicle to be tested in fig. 5 is an abnormal vehicle (e.g., a vehicle involved in a case).
In some embodiments of the disclosure, for each journey, the passing cost of each gate in the journey is calculated, and the stability degree of the passing cost is represented by a mathematical variance. If the speed is stable and is always in a state of being faster or slower than others, the variance is minimum; this trip may be problematic if the speed is sometimes faster than others and sometimes slower than others.
In some embodiments of the present disclosure, step 21 may identify an abnormal condition that the vehicle passes through the abnormal number of gates (circle winding), and the vehicle track abnormal model in fig. 3 may be used to identify an abnormal condition that the vehicle passes through the abnormal number of gates (circle winding). At this time, step 21 may include: and comparing the number of the bayonets passed by the vehicle to be detected in one stroke with the number of the bayonets passed by the vehicle in the same stroke and travel time period, and determining whether the number of the bayonets passed by the vehicle to be detected is abnormal.
In some embodiments of the present disclosure, step 21 may comprise: determining vehicles in the same trip and same trip time period, wherein the first traffic light passing in the trip is the same, the last traffic light is the same, and the time period passing through the first traffic light is the same to be used as the vehicles in the same trip and same trip time period; sequencing the quantity of the bayonets passed by the vehicles in the same travel and same trip time period from large to small, and dividing the bayonets into 9 sections (9 grades), wherein the bayonets pass through the 1 grade at least, and the bayonets pass through the 9 grades at the most, and the grade is taken as the passing cost; and defining the vehicles represented by the deviated group as abnormal vehicles according to the discrete degree of the vehicle group to be detected and the vehicles in the same trip time period.
FIG. 6 is a schematic diagram of a traffic cost table in some embodiments of the present disclosure. Each row as shown in fig. 6 identifies a trip; presetting the number of bayonets of 9 gears for each stroke in a traffic cost table; and the darker one is the number of the bayonets passed by the vehicle to be tested in the journey.
As is apparent from the data in fig. 6, the trip 2 is a vehicle trip path when a case (e.g., a poison) is caught, and it can be seen that: when the drug-related personnel do not carry drugs, the shortest path is selected, and the traffic cost is the minimum. Once carrying drugs, the drug-related personnel need to take comprehensive consideration, and often detour in the same departure place and destination, compared with the vehicles (with the same departure point and destination), the number of passing bayonets is obviously more than the normal value, and the traffic cost index reflects the phenomenon of detour by comparing the number of passing bayonets with the traffic cost comparison table.
In the above embodiments of the present disclosure, the involved personnel tend to select the shortest path when not doing a case, and the traffic cost is the minimum. In case of crime, the involved personnel need to comprehensively consider, and in the same departure place and destination, the involved personnel need to bypass the inspection opening for avoiding inspection, so that compared with vehicles in the same journey (the same departure point, the same purpose and the same trip time period), the number of passing bayonets is obviously more than the normal value.
In some embodiments of this disclosure, step 21 can discern the abnormal conditions of vehicle transit time anomaly (rub-and-rub), and the abnormal conditions of vehicle orbit model in fig. 3 can be used for discerning the vehicle transit time anomaly (rub-and-rub). At this time, step 21 may include: and comparing the total passing time of the vehicle to be detected in one trip with the total passing time of the same trip and the same trip time period, and determining whether the total passing time of the vehicle to be detected is abnormal.
In some embodiments of the present disclosure, step 21 may comprise: determining vehicles in the same trip and same trip time period, wherein the first traffic light passing in the trip is the same, the last traffic light is the same, and the time period passing through the first traffic light is the same to be used as the vehicles in the same trip and same trip time period; sorting the time spent by vehicles in the same trip and same trip time period from large to small, and dividing the time into 9 sections (9 grades), wherein the least spent time is 1 grade, and the most spent time is 9 grades, and the grading is used as the time cost; and defining the vehicle with the largest time cost as an abnormal vehicle.
FIG. 7 is a schematic diagram of a time cost table in some embodiments of the present disclosure. Line 3 (bar 3) in fig. 7 is the vehicle trajectory when grasped.
In the above embodiment, due to detour and psychological pressure, the vehicle involved in a case may pass through more gates and spend more time in the total running process and wait for more favorable passing time, all of which are represented as abrasion and rubbing, compared with the vehicle in the same journey (same starting point-destination-time period) during the process of a crime.
And step 22, judging whether the vehicle to be detected has abnormal vehicle traveling conditions according to the vehicle monitoring index to be detected.
In some embodiments of the present disclosure, step 22 may comprise: and inputting the monitoring indexes of the vehicle to be detected into the abnormal vehicle travel model to obtain the abnormal vehicle travel condition.
In some embodiments of the present disclosure, as shown in fig. 3, the abnormal vehicle traveling condition may include at least one of an abnormal vehicle traveling destination condition, an abnormal vehicle traveling frequency condition, and an abnormal vehicle traveling time condition.
In some embodiments of the present disclosure, as shown in fig. 3, the abnormal vehicle travel condition may include at least one of an abnormal condition of dense treading, dense trading, dense joints, no wind noise leakage, and the like.
