Referring to fig. 3, fig. 3 is a flowchart illustrating a method for following a vehicle when the vehicle is present, which may be applied to an electronic device and may include the following steps.
Step 301: and acquiring the license plate number of the first license plate on the outgoing vehicle acquired by the first image acquisition equipment.
The departure vehicle refers to any vehicle entering an exit of the parking lot, in other words, any vehicle about to leave the parking lot.
The first image acquisition device can be a coil type trigger image acquisition device, and the coil can trigger the first image acquisition device to capture a license plate image of a first license plate on a vehicle. For example, the first license plate is a license plate on the head position of the departure vehicle.
In an optional implementation manner, the first image acquisition device may perform license plate number recognition on the license plate image of the first license plate to obtain the license plate number of the first license plate. Then, the first image capturing device may send the identified license plate number of the first license plate to the electronic device.
In another alternative implementation, the first image capture device may send the license plate image of the first license plate to the electronic device. The electronic equipment can identify the license plate number of the license plate image of the first license plate to obtain the license plate number of the first license plate.
The "acquiring the license plate number of the first license plate on the outgoing vehicle acquired by the first image acquisition device" is not specifically limited herein.
Step 302: and inquiring the payment information of the outgoing vehicle based on the license plate number of the first license plate.
Step 303: and triggering second image acquisition equipment to acquire the license plate number when the outgoing vehicle is determined to finish payment.
The electronic equipment also maintains a record table of the payment condition of each vehicle in the parking lot. The number plate number and payment information of each vehicle are recorded in the recording table. The payment information may include: payment amount, whether payment is completed, etc. The payment information is not specifically limited here.
In the implementation process, the electronic device can search the payment information corresponding to the license plate number of the first license plate in the record table.
If the payment information indicates that the outgoing vehicle finishes payment, the electronic equipment can trigger the second image acquisition equipment to acquire the license plate number. For example, the electronic device may issue a first acquisition instruction to the second image acquisition device, and the second image acquisition device starts license plate number acquisition after receiving the first acquisition instruction. Of course, the electronic device may also trigger the second image capturing device to capture the license plate number in other manners, which are only exemplary and not specifically limited herein.
If the payment information indicates that the vehicle is not finished paying, the electronic equipment can carry out payment processing on the vehicle.
For example, the electronic device may issue payment information to a terminal device deployed at an exit of the parking lot, and the terminal device may display the payment information to prompt the user to complete payment. For example, the electronic device may issue a payment amount to an LED screen disposed at an exit of the parking lot. The LED screen can show the payment amount to the user to remind the user to finish payment.
Of course, the electronic device may also send payment information to a user terminal (such as a computer, a mobile phone, etc.) of a parking center attendant, so that the attendant reminds the vehicle to pay.
After the vehicle payment is completed, the electronic equipment can trigger the second image acquisition equipment to acquire the license plate number.
Step 304: detecting whether the license plate number of a second license plate on the outgoing vehicle acquired by second image acquisition equipment is acquired within a first preset time period from the time when the second image acquisition equipment is triggered to acquire the license plate number; the first license plate and the second license plate are different in the arrangement position of the vehicle.
It should be noted that the first license plate and the second license plate are disposed at different positions on the departure vehicle. For example, the first license plate is disposed at the head of the departure vehicle, and the second license plate is disposed at the tail of the departure vehicle.
The positions of the first license plate and the second license plate on the departure vehicle are only exemplarily illustrated and are not particularly limited.
It should be noted that, if the vehicle is not followed by the departure vehicle, the time consumed for the second image capturing device to capture the license plate number of the second license plate of the departure vehicle is very short, so that the departure vehicle can rapidly depart, and in order to avoid the departure vehicle being followed when waiting for the barrier gate to be opened, the first preset time duration may be set to be a short time duration, for example, 500 milliseconds, 1 second, and the specific value of the first preset time duration is not limited in this embodiment.
In an optional implementation manner, the electronic device starts a timer when triggering the second image capturing device to capture the license plate number.
Then, the electronic device can detect whether the license plate number acquired by the second image acquisition device is acquired within the timeout duration of the timer.
1) The license plate number acquired by the second image acquisition equipment is not acquired within the overtime length of the timer
If the license plate number acquired by the second image acquisition device is not acquired within the timeout duration of the timer, the electronic device may determine that the license plate number of the second license plate on the departure vehicle acquired by the second image acquisition device is not acquired within a first preset duration from the time when the second image acquisition device is triggered to acquire the license plate number.
2) If the license plate number acquired by the second image acquisition equipment is acquired within the overtime length of the timer
If the license plate number acquired by the second image acquisition device is acquired within the overtime duration of the timer, the electronic device can further detect whether the license plate number of the first license plate is the same as the acquired license plate number.
If the license plate number of the first license plate is the same as the acquired license plate number, the electronic equipment can determine that the acquired license plate number is the license plate number of a second license plate on the outgoing vehicle, and determines that the license plate number of the second license plate on the outgoing vehicle acquired by the second image acquisition equipment is acquired within a first preset time period from the time when the second image acquisition equipment is triggered to acquire the license plate number of the second license plate on the outgoing vehicle.
If the license plate number of the first license plate is different from the acquired license plate number, the electronic equipment can determine that the license plate number of the second license plate on the outgoing vehicle acquired by the second image acquisition equipment is not acquired within a first preset time period from the time when the second image acquisition equipment is triggered to acquire the license plate number.
Step 305: and if the license plate number of the second license plate on the outgoing vehicle acquired by the second image acquisition equipment is not acquired within a first preset time period from the time when the second image acquisition equipment is triggered to acquire the license plate number, determining that the outgoing vehicle is followed.
It should be noted that, when the departure vehicle is followed, the first image capturing device may capture the license plate number of the first license plate (such as the head license plate) on the departure vehicle, but since the following vehicle covers the second license plate (such as the tail license plate) on the departure vehicle, the second image capturing device cannot capture the license plate number of the second license plate on the departure vehicle, and cannot send the license plate number of the second license plate on the departure vehicle to the electronic device.
Therefore, when the electronic equipment judges whether the outgoing vehicle is followed according to whether the license plate number of the second license plate is acquired within a first preset time period from the moment when the second image acquisition equipment is triggered to acquire the license plate number.
Specifically, if the license plate number of the second license plate on the outgoing vehicle acquired by the second image acquisition device is not acquired within a first preset time period from the time when the second image acquisition device is triggered to acquire the license plate number, the electronic device may determine that the outgoing vehicle is followed.
And if the license plate number of the second license plate on the outgoing vehicle acquired by the second image acquisition equipment is acquired within a first preset time from the moment when the second image acquisition equipment is triggered to acquire the license plate number, the electronic equipment can determine that the outgoing vehicle is not followed.
1) Vehicle following by vehicle on departure
When the electronic equipment determines that the vehicle is followed, the electronic equipment can issue a first vehicle following alarm to the terminal equipment deployed at the exit of the parking lot.
For example, the electronic device may issue a voice or text warning message to an LED screen deployed at the exit of the parking lot, such as "the rear car is too close to the departure vehicle a12345, and does not follow the car".
Of course, the electronic device may also send a second car following warning to the user terminal of the parking lot center attendant.
For example, the electronic device may issue the second warning message to a terminal device such as a computer or a mobile phone of the parking lot center attendant through an instant message or a mail. And after receiving the second car following alarm, the central guard personnel carries out on-site scheduling so that the rear car is far away from the vehicles on the spot.
Of course, the electronic device may also issue a first car following alarm to the terminal device deployed at the exit of the parking lot, and send a second car following alarm to the user terminal of the parking lot center attendant.
The first following warning and the second following warning may be the same following warning or different following warnings, and are not specifically limited herein.
2) Leaving vehicles not being followed
When the electronic device determines that the departing vehicle is not followed, the electronic device may issue a control instruction for releasing the departing vehicle to a barrier gate disposed at the exit of the parking lot to control the barrier gate to release the departing vehicle. And after receiving the control command, the barrier gate can be opened to allow the vehicles to leave the parking lot.
In addition, in this application embodiment, in order to guarantee that the vehicle of leaving the parking lot still can guarantee that the vehicle of leaving the parking lot leaves the parking lot smoothly after disappearing with the car, to the vehicle of leaving the parking lot that is followed, electronic equipment still can carry out following processing:
when it is determined that the vehicle is followed, the electronic device can trigger the second image acquisition device to start the license plate number acquisition lasting for a second preset time, and send the acquired license plate number to the electronic device.
For example, the electronic device may send a second acquisition instruction to the second image acquisition device, where the second acquisition instruction may carry a second preset duration. After receiving the second acquisition instruction, the second image acquisition device can acquire the license plate number within a second preset time from the time of receiving the second acquisition instruction, and send the acquired license plate number to the electronic device.
For example, after receiving the second acquisition instruction, the second image acquisition device may acquire the license plate number at regular time within a second preset time period from when the second acquisition instruction is received. Of course, the second image capturing device may randomly capture the license plate number at random, which is only exemplary and not particularly limited.
The electronic device may detect whether the license plate number of the second license plate of the departure vehicle acquired by the second image acquisition device is acquired within a third preset time period from when the departure vehicle is determined to be followed.
If the license plate number of the second license plate of the departure vehicle acquired by the second image acquisition equipment is acquired within a third preset time period from the moment when the departure vehicle is determined to be followed, the fact that the following of the departure vehicle disappears is indicated. The electronic equipment can send a release control instruction to a barrier gate deployed at the exit of the parking lot so as to control the barrier gate to release the vehicles on the departure.
If the license plate number of the second license plate of the departure vehicle acquired by the second image acquisition equipment is not acquired within a third preset time period from the moment when the departure vehicle is determined to be followed, it is indicated that the departure vehicle is still followed. When the vehicle is determined to be followed, the electronic equipment can issue a third vehicle following alarm to the terminal equipment of the central guard of the parking lot, so that the guard can carry out on-site scheduling and the rear vehicle can retreat for a specified distance.
It should be noted that the second preset duration may be set according to an actual scene, for example, the second preset duration may be set with reference to a time-consuming duration from when the vehicle is followed by the vehicle, to when the electronic device issues a vehicle following alarm, and then to when the rear vehicle is retracted by a certain distance. Of course, the second preset time length can be set for the impasse that the rear vehicle does not retreat and the vehicle on the spot cannot come on the spot later. For example, the second preset time period may be set to 30 seconds, 1 minute, etc., and the embodiment does not limit the specific value of the second preset time period.
In addition, considering that it takes time for the second image capturing device to capture the license plate number and send the license plate number to the electronic device, the third preset time period may be set to be longer than the second preset time period. And because the time consumed for acquiring the license plate number by the second image acquisition device and sending the license plate number to the electronic device is very short, the third preset time duration can also be set to be the same as the second preset time duration. The specific value of the third preset time period is not limited herein.
The third following warning may be the same as or different from the first and second following warnings, and is not limited specifically herein.
As can be seen from the above description, in one aspect, the present application provides a first image capturing device for capturing a license plate number of a first license plate on a vehicle on the parking lot, and a second image capturing device for capturing a license plate number of a second license plate on the vehicle on the parking lot.
When the outgoing vehicle is followed, the first image acquisition equipment can acquire the license plate number of a first license plate (such as a head license plate) on the outgoing vehicle, but the following vehicle covers a second license plate (such as a tail license plate) on the outgoing vehicle, so that the second image acquisition equipment cannot acquire the license plate number of a second license plate of the outgoing vehicle and cannot send the license plate number of the second license plate of the outgoing vehicle to the electronic equipment.
Therefore, the electronic equipment can judge whether the vehicle is followed or not based on whether the license plate number of the second license plate is acquired within the first preset time from the triggering of the second image acquisition equipment for license plate number acquisition, so that the problem of following fee evasion can be effectively prevented.
On the other hand, when the situation that the payment of the vehicles is completed and the vehicles are not followed is determined, the electronic equipment can control the barrier gate to open the vehicles which are going out of the parking lot, and when the electronic equipment determines that the vehicles which are going out of the parking lot are followed, the electronic equipment can also issue alarm information to enable the vehicles which are followed to retreat, so that a closed-loop system which has the functions of vehicle following determination, parking charging and alarm is formed, the accuracy of parking charging of unattended parking is greatly improved, and the vehicles which are followed to run away is effectively prevented from occurring.
The third aspect, after confirming that the vehicle of leaving is followed the car, this application still provides with the detection whether the car disappears to guarantee that the vehicle of leaving can leave the parking area smoothly with the car disappearance back at the vehicle of leaving.
The following determination method for the outgoing vehicle provided by the present application is described in detail below by taking the first license plate as the head license plate of the outgoing vehicle and the second license plate as the tail license plate of the outgoing vehicle as an example.
Referring to fig. 4, fig. 4 is a flowchart illustrating another vehicle following method for a departure vehicle according to an exemplary embodiment of the present application.
The method can be applied to electronic equipment and can comprise the following steps.
Step 401: the electronic equipment acquires the license plate number of the head license plate of the outgoing vehicle acquired by the snapshot machine 1.
Step 402: the electronic equipment inquires the payment information of the outgoing vehicle based on the license plate number of the vehicle head and license plate.
Step 403: and when the electronic equipment determines that the outgoing vehicle finishes payment, triggering the snapshot machine 2 to collect the license plate number.
Step 404: the electronic equipment detects whether the license plate number of the tail of the vehicle which is acquired by the snapshot machine 2 is acquired within a first preset time from the time when the snapshot machine 2 is triggered to acquire the license plate number.
In implementation, when the electronic device can trigger the snapshot machine 2 to collect the license plate number, the timer is started, and the timeout duration of the timer is set to be the first preset duration.
The electronic equipment can detect whether the license plate number acquired by the snapshot machine 2 is acquired within the overtime length of the timer.
If the license plate number acquired by the snapshot machine 2 is not acquired within the overtime duration of the timer, it is determined that the license plate number of the tail of the outgoing vehicle acquired by the snapshot machine 2 is not acquired within a first preset duration from the time when the snapshot machine 2 is triggered to acquire the license plate number.
If the license plate number acquired by the snapshot machine 2 is acquired within the overtime length of the timer, detecting whether the license plate number acquired by the snapshot machine 2 is the same as the license plate number of the vehicle head;
if the license plate number acquired by the snapshot machine 2 is the same as that of the vehicle head, determining that the license plate number of the tail of the outgoing vehicle acquired by the snapshot machine 2 is acquired within a first preset time period from the time when the snapshot machine 2 is triggered to acquire the license plate number;
if the license plate number acquired by the snapshot machine 2 is different from the license plate number of the vehicle head license plate, it is determined that the license plate number of the vehicle at the tail of the departure vehicle acquired by the snapshot machine 2 is not acquired within a first preset time period from the time when the snapshot machine 2 is triggered to acquire the license plate number.
It should be further noted that, if the electronic device obtains the license plate number of the tail of the outgoing vehicle collected by the snapshot machine 2 within a first preset time period from when the snapshot machine 2 is triggered to collect the license plate number, the steps 405 to 406 are executed.
And if the license plate number of the tail of the vehicle which is acquired by the snapshot machine 2 is not acquired within the first preset time from the moment when the snapshot machine 2 is triggered to acquire the license plate number, executing the steps 407 to 411.
Step 405: if the electronic equipment acquires the license plate number of the tail of the outgoing vehicle acquired by the snapshot machine 2 within a first preset time period from the time when the snapshot machine 2 is triggered to acquire the license plate number, it is determined that the outgoing vehicle is not followed.
Step 406: and the electronic equipment sends a release control instruction to a barrier gate deployed at the exit of the parking lot so as to control the barrier gate to release the vehicles on the departure.
Step 407: if the license plate number of the tail of the outgoing vehicle acquired by the snapshot machine 2 is not acquired within a first preset time period from the time when the snapshot machine 2 is triggered to acquire the license plate number, the electronic equipment determines that the outgoing vehicle is followed.
Step 408: and the electronic equipment sends a car following alarm to the terminal equipment at the exit of the parking lot and triggers the snapshot machine 2 to start the license plate number acquisition lasting for a second preset time.
Step 409: and the electronic equipment detects whether the license plate number of the tail of the vehicle of the departure acquired by the snapshot machine 2 is acquired within a third preset time from the moment when the departure vehicle is determined to be followed.
During implementation, the electronic equipment can detect whether the license plate number acquired by the snapshot machine 2 is acquired within a third preset time period from the moment when the departure vehicle is determined to be followed;
if the license plate number acquired by the snapshot machine 2 is not acquired within the third preset time period from the time when the departure vehicle is determined to be followed, determining that the license plate number of the rear of the departure vehicle acquired by the snapshot machine 2 is not acquired within the third preset time period from the time when the departure vehicle is determined to be followed;
if the license plate number collected by the snapshot machine 2 is obtained within a third preset time period from the moment when the departure vehicle is determined to be followed, comparing whether the collected license plate number is the same as the license plate number of the head license plate;
if the acquired license plate number is the same as that of the vehicle head license plate, the electronic equipment determines that the license plate number of the tail of the outgoing vehicle acquired by the snapshot machine 2 is acquired within a third preset time period from the moment when the outgoing vehicle is determined to be followed;
if the acquired license plate number is different from the license plate number of the vehicle head license plate, the electronic equipment can determine that the license plate number of the vehicle tail of the departure vehicle acquired by the snapshot machine 2 is not acquired within a third preset time period from the moment when the departure vehicle is determined to be followed.
It should be noted that, if the electronic device obtains the license plate number of the vehicle tail of the departure vehicle collected by the snapshot machine 2 within the third preset time period after the departure vehicle is determined to be followed, step 410 is executed.
If the electronic device does not acquire the license plate number of the vehicle tail of the departure vehicle acquired by the snapshot machine 2 within a third preset time period from the time when the electronic device determines that the departure vehicle is followed, step 411 is executed.
Step 410: if the electronic equipment acquires the license plate number of the tail of the vehicle of the departure collected by the snapshot machine 2 within a third preset time period from the moment when the electronic equipment determines that the departure vehicle is followed, the electronic equipment determines that the following vehicle disappears and sends a release control instruction to the barrier gate so as to control the barrier gate to release the departure vehicle.
Step 411: if the electronic equipment does not acquire the license plate number of the tail of the outgoing vehicle collected by the snapshot machine 2 within a third preset time period from the time when the electronic equipment determines that the outgoing vehicle is followed, the electronic equipment determines that the following vehicle does not disappear, and issues a continuous vehicle-changing alarm to a user terminal of a central guard of the parking lot.
As can be seen from steps 408 to 411, in practical applications, most of the following vehicles will recede after sensing the warning information, and only a few of the following vehicles will not recede, so that the electronic device can issue a following warning to the terminal device at the exit of the parking lot to prompt the following vehicle to recede after determining that the vehicle is followed. And when the electronic equipment determines that the car is delayed and not disappeared, the electronic equipment sends a car following alarm to the terminal equipment of the parking lot watchman so as to remind the watchman to intervene manually to promote the car following to retreat, so that the manual intervention degree can be greatly reduced, and the parking lot management is more intelligent.
As can be seen from the above description, on the one hand, the snapshot machine 1 for collecting the license plate number of the head license plate of the outgoing vehicle and the snapshot machine 2 for collecting the license plate number of the tail license plate of the outgoing vehicle are respectively arranged in the parking lot.
When the vehicles are followed, the snapshot machine 1 can collect the license plate numbers of the head license plates of the vehicles, but the tail license plates of the vehicles are covered by the following vehicles, so that the snapshot machine 2 cannot collect the license plate numbers of the tail license plates of the vehicles and cannot send the tail license plates of the vehicles to the electronic equipment.
Therefore, the electronic equipment can judge whether the vehicle is followed or not based on whether the license plate number of the vehicle tail license plate is acquired within the first preset time from the moment that the snapshot machine 2 is triggered to acquire the license plate number, so that the problem of fee evasion from following can be effectively prevented.
On the other hand, when the situation that the payment of the vehicles is completed and the vehicles are not followed is determined, the electronic equipment can control the barrier gate to open the vehicles which are going out of the parking lot, and when the electronic equipment determines that the vehicles which are going out of the parking lot are followed, the electronic equipment can also issue alarm information to enable the vehicles which are followed to retreat, so that a closed-loop system which has the functions of vehicle following determination, parking charging and alarm is formed, the accuracy of parking charging of unattended parking is greatly improved, and the vehicles which are followed to run away is effectively prevented from occurring.
The third aspect, after confirming that the vehicle of leaving is followed the car, this application still provides with the detection whether the car disappears to guarantee that the vehicle of leaving can leave the parking area smoothly with the car disappearance back at the vehicle of leaving.
