Description

Technical Field

[0001] This invention relates to the technical field of vehicle access management, and in particular to a method, device, medium, and equipment for identifying vehicles traveling in the wrong direction in a parking lot. Background Technology

[0002] Dropping off passengers at the parking lot entrance, reversing or making U-turns in the open area at the entrance, etc., can all cause the license plate to be recognized by the parking lot entrance control machine and the gate to open. If a vehicle leaves directly after the gate opens without entering the parking lot, the gate will remain open for a period of time to allow vehicles to pass. During this period of time, vehicles leaving the parking lot may take advantage of the gate's continued openness to exit from the parking lot entrance in the opposite direction. In unattended parking lots, some people collude to evade payment by driving without entering after the gate is recognized at the entrance, and then exiting through the entrance after the gate opens, maliciously avoiding payment.

[0003] In addition, when a vehicle that needs to leave is driven to the exit area, it is recognized by the parking lot exit control machine and the gate is opened. When the vehicle does not leave the parking lot, the gate will remain open for a period of time to wait for the vehicle to pass. During this time, the vehicle may take advantage of the time gap when the gate is open to enter the parking lot from the opposite direction of the exit. As a result, when the vehicle leaves the parking lot, the entry record of the vehicle cannot be found, and the normal charging process for the vehicle cannot be processed, which affects the management order of the parking lot management. Summary of the Invention

[0004] Based on this, it is necessary to propose a parking lot vehicle reverse passage identification method, device, medium and equipment to address the above problems and solve the following issues of the existing technology: vehicles leaving or entering the parking lot in reverse, affecting the management order of the parking lot management, and causing losses due to vehicles maliciously evading payment.

[0017] According to the parking lot vehicle reverse traffic identification method provided by the present invention, the fourth time value corresponding to the direction in which the target vehicle is driven away from the camera, as identified by the monitoring and recording third controller, includes:

[0018] When the target vehicle enters the vehicle recognition area through the third controller, the driving direction of the vehicle recognized by the third controller is obtained, wherein the driving direction of the vehicle is obtained based on the real-time monitoring video captured by the camera;

[0019] If the vehicle is driving in a direction away from the camera, then record the fourth time value of the target vehicle driving in a direction away from the camera.

[0020] According to the present invention, a method for identifying vehicles traveling in the wrong direction in a parking lot includes identifying whether a target vehicle is traveling in the wrong direction based on a first transition time value, a second transition time value, a third transition time value, and a fourth time value.

[0021] Determine the first time difference between the second transition time value and the first transition time value;

[0022] Determine the second time difference between the fourth time value and the third jump time value;

[0023] Based on the first time difference and the second time difference, it is determined whether the target vehicle is traveling in the wrong direction.

[0024] According to the present invention, a method for identifying vehicles traveling in the wrong direction in a parking lot includes determining whether the target vehicle is traveling in the wrong direction based on a first time difference and a second time difference, comprising:

[0025] If the first time difference is greater than 0 and less than the first time threshold, and the second time difference is greater than 0 and less than the second time threshold, then the target vehicle is determined to be traveling in the wrong direction.

[0026] According to the present invention, a parking lot vehicle reverse traffic identification method further includes, after determining that the target vehicle is traveling in the wrong direction, the method further includes:

[0027] If the type of the third control unit is an entrance control unit, then it is determined that the target vehicle is exiting in reverse and a reverse exit warning message is generated to collect the toll from the target vehicle.

[0028] If the third controller is an exit controller, it is determined that the target vehicle is entering in the opposite direction and an entry record of the target vehicle is generated, so as to control the exit of the target vehicle based on the entry record.

This can filter out the algorithm's own misjudgment of vehicle direction, as well as the misjudgment caused by relying solely on ground sensor direction judgment, to obtain a highly reliable reverse passage identification result, thereby improving the management order of parking lots, recovering parking fees from vehicles that evade payment, and reducing losses.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the equipment deployment at the parking lot entrance provided by the present invention. Figure 2 This is a schematic diagram of the equipment deployment at a parking lot exit provided by the present invention. The equipment deployment is performed first, and there are no special requirements; it can be configured and installed according to the standard installation and deployment methods of conventional parking control management systems and equipment. The hardware structure of the present invention mainly relies on devices such as a barrier gate, camera, first detector, second detector, and third controller in a conventional parking control management system and equipment. The camera is communicatively connected to the third controller, allowing real-time monitoring video captured by the camera to be transmitted to the third controller for vehicle recognition and other operations. Optionally, the first detector is a barrier gate ground sensor detector, the second detector is a controller ground sensor detector, and the third controller can be configured as an entrance controller or an exit controller depending on the actual scenario.

[0047] The equipment deployment instructions are as follows:

[0048] 1. Ground Loop Detector: In traditional parking lots, this device is used to detect whether there is a vehicle in front of the barrier gate or to trigger the detection of vehicles without license plates. It is a standard feature in most parking lots. When a vehicle enters the detector area, it outputs a vehicle presence signal; when no vehicle is present, it switches to a no-vehicle signal. When a vehicle crosses the ground loop, it will notify the system to output a vehicle presence signal; otherwise, it outputs a no-vehicle signal.

[0049] 2. Barrier gate ground sensor: In traditional parking lots, it is used to detect whether there is a vehicle under the barrier gate. When there is a vehicle, the barrier gate cannot be closed to prevent vehicles from blocking people. Another important function is that the barrier gate uses the voltage level change of this barrier gate ground sensor to control the barrier gate to close. When the barrier gate ground sensor changes from a vehicle presence to no vehicle presence (the gate closes instantly during the transition), the barrier gate will automatically lower. The control machine is responsible for controlling the barrier gate to open. After the vehicle passes, the barrier gate will automatically close.

[0050] 3. Control unit: The control unit has a built-in license plate recognition device, which can realize license plate recognition. At the same time, the license plate recognition algorithm can also determine whether the vehicle is approaching or moving away from the camera based on the size change of the license plate pixels in the image or the movement trajectory of the license plate, and then output the directional result of approaching or moving away from the camera.

[0051] The control unit installed at the entrance of the parking lot is called the entrance control unit, and the control unit installed at the exit of the parking lot is called the exit control unit. In addition, a barrier gate and a barrier gate controller are installed at the entrance and exit of the parking lot, respectively. The barrier gate controller controls the barrier gate to open to allow vehicles to pass or to close to block vehicles, i.e., to open or close the gate. A barrier gate ground sensor and a controller ground sensor are installed on the outside of the entrance and the inside of the exit of the parking lot, respectively. Optionally, the barrier gate ground sensor is installed on the ground in the lane near the barrier gate or corresponding to the position below the barrier gate, and the controller ground sensor is installed on the ground in the lane away from the barrier gate and close to the controller or corresponding to the controller.

[0052] Reference Figure 3 , Figure 3 This is a flowchart illustrating the parking lot vehicle reverse passage identification method provided in an embodiment of the present invention. The present invention also provides a parking lot vehicle reverse passage identification method, including the following steps:

[0053] Step S11: Monitor and record the first transition time value of the change in the detection signal of the first detector;

[0054] It should be noted that the first detector is a ground sensor detector of the barrier gate that is pre-set in the barrier gate detection area, and the first transition time value represents the time value corresponding to the transition from the detection signal of no vehicle to the detection signal of vehicle presence.

[0055] Specifically, when there are no vehicles in the gate detection area, the gate ground sensor outputs a vehicle-free detection signal. When a target vehicle drives through the gate detection area, the gate ground sensor can detect the vehicle's passage and output a vehicle-present detection signal. This allows for real-time monitoring and recording of the first transition time value corresponding to the gate ground sensor's change from a vehicle-free detection signal to a vehicle-present detection signal.

[0056] Optionally, since the detection signal output by the barrier gate ground sensor changes from a vehicle-free detection signal to a vehicle-present detection signal and finally to a vehicle-free detection signal when a vehicle passes through, in other embodiments, the first transition time value can also be set as the time value corresponding to the transition from a vehicle-present detection signal to a vehicle-free detection signal. That is, the first transition time value corresponding to the change from a vehicle-present detection signal to a vehicle-free detection signal by the barrier gate ground sensor is monitored and recorded in real time.

[0057] Step S12: Monitor and record the second and third transition time values ​​of the detection signal of the second detector.

[0058] It should be noted that the second detector is a ground sensor detector of the controller that is pre-set in the detection area of ​​the controller. The second transition time value represents the time value corresponding to the transition from the detection signal of no vehicle to the detection signal of vehicle. The third transition time value represents the time value corresponding to the transition from the detection signal of vehicle to the detection signal of no vehicle.

[0059] Specifically, when a vehicle passes, the detection signal output by the ground induction detector of the controller changes from a vehicle-free detection signal to a vehicle-present detection signal, and finally back to a vehicle-free detection signal. The changes and transition time values ​​of the detection signal from the ground induction detector of the controller are monitored and recorded in real time. Based on these changes, the second transition time value corresponding to the change from a vehicle-free detection signal to a vehicle-present detection signal, and the third transition time value corresponding to the change from a vehicle-present detection signal to a vehicle-free detection signal, are determined.

[0060] Step S13: Monitor and record the fourth time value corresponding to the direction in which the target vehicle is driving away from the camera, as identified by the third controller;

[0061] It should be noted that the third control unit is a pre-installed entrance control unit or exit control unit. The camera associated with the third control unit can capture images or videos of vehicles passing through the vehicle recognition area. The entrance control unit or exit control unit has a built-in license plate recognition device. The license plate recognition device identifies the license plate number in the image or video captured by the camera through a license plate recognition algorithm. At the same time, the license plate recognition algorithm of the recognition device can also determine whether the vehicle is driving towards or away from the camera based on the size change of the license plate pixels in the image or video, or the movement trajectory of the license plate.

[0062] Specifically, when the target vehicle enters or exits in reverse, the driving direction of the target vehicle is away from the camera. Therefore, in this embodiment, it is necessary to monitor and record the fourth time value corresponding to the direction in which the target vehicle is driving away from the camera, as identified by the third controller.

[0063] Step S14: Based on the first transition time value, the second transition time value, the third transition time value, and the fourth time value, identify and determine whether the target vehicle is traveling in the wrong direction.

[0064] It should be noted that when a vehicle exits the parking lot in the wrong direction at the entrance or enters the parking lot in the wrong direction at the exit, it first passes through the barrier gate detection area, then the control unit detection area, and finally the vehicle identification area. Therefore, the order of signal changes from the barrier gate's ground sensor and the control unit's ground sensor, combined with the vehicle's departing driving direction identification result output by the third control unit, is used to determine whether the vehicle is traveling in the wrong direction. Therefore, in this embodiment, specifically, the magnitudes of the first transition time value, the second transition time value, the third transition time value, and the fourth time value can be compared to identify whether the target vehicle is traveling in the wrong direction. Understandably, when a vehicle exits the parking lot in the wrong direction at the entrance or enters the parking lot in the wrong direction at the exit, the first transition time value is less than the second transition time value, the second transition time value is less than the third transition time value, and the third transition time value is less than the fourth time value.

[0065] This invention accurately identifies whether a target vehicle is traveling in the wrong direction by recording the jump time values ​​of changes in the detection signals of the first and second detectors in real time, and combining this with the time value of the vehicle moving away from the camera as identified by the third controller. This can filter out misjudgments of vehicle direction by the algorithm itself, as well as misjudgments caused by relying solely on ground sensor direction judgment, resulting in a highly reliable reverse traffic identification result. This improves parking lot management order, allows for the recovery of parking fees from evading vehicles, and reduces losses.

[0066] In one embodiment of the present invention, the real-time monitoring and recording of the first transition time value of the change in the detection signal of the first detector includes:

[0067] When the barrier gate is detected to be in the open state, the monitoring records the first transition time value of the first detector from the first detection signal to the second detection signal.

[0068] It should be noted that the third detection signal indicates that there is no vehicle in the control unit's detection area, while the fourth detection signal indicates that there is a vehicle in the control unit's detection area. Specifically, after the gate is detected to be open, real-time monitoring begins to detect whether there is any malicious reverse entry or exit of a vehicle. In this embodiment, the changes in the detection signal and transition time value of the gate's ground sensor are recorded. Understandably, the initial value of the first transition time value is 0. The first transition time value is the time when the gate's ground sensor changes from a no-vehicle detection signal to a vehicle-present detection signal. Each transition from a no-vehicle detection signal to a vehicle-present detection signal refreshes the first transition time value.

[0069] In one embodiment of the present invention, the monitoring and recording of the second transition time value and the third transition time value of the change in the detection signal of the second detector includes:

[0070] The second transition time value of the second detector from the third detection signal to the fourth detection signal is monitored and recorded; the third transition time value of the second detector from the fourth detection signal to the third detection signal is also monitored and recorded.

[0071] It should be noted that the third detection signal indicates that there is no vehicle in the detection area of ​​the controller, while the fourth detection signal indicates that there is a vehicle in the detection area of ​​the controller. Specifically, the changes and transition times of the detection signals of the controller's ground sensor are recorded. Understandably, the initial values ​​of the second and third transition times are 0. The second transition time value is the time when the controller's ground sensor transitions from a vehicle-free detection signal to a vehicle-present detection signal, and the third transition time value is the time when the controller's ground sensor transitions from a vehicle-present detection signal to a vehicle-free detection signal. Each transition of the detection signal refreshes the corresponding transition time value.

[0072] In one embodiment of the present invention, the fourth time value corresponding to the direction in which the target vehicle is driving away from the camera, as identified by the third controller, includes:

[0073] When the third controller detects that the target vehicle has entered the vehicle recognition area, the driving direction of the vehicle is obtained by the third controller. The driving direction of the vehicle is obtained based on the real-time monitoring video captured by the camera. If the driving direction of the vehicle is driving away from the camera, a fourth time value of the target vehicle driving away from the camera is recorded.

[0074] It should be noted that the vehicle driving direction includes driving away from the camera or driving towards the camera. When a vehicle enters the vehicle recognition area, the third controller identifies the license plate number at the rear of the vehicle. Optionally, the third controller is connected to the camera. The third controller can perform vehicle recognition analysis based on the real-time monitoring video captured by the camera to obtain the license plate number in the real-time monitoring video. It can also determine whether the vehicle's driving direction is towards or away from the camera based on the size changes of the license plate number's pixels in the real-time monitoring video or on the movement trajectory of the license plate number. Specifically, when the target vehicle enters the vehicle recognition area, the driving direction of the target vehicle identified by the third controller is obtained. If the vehicle's driving direction is away from the camera, the moment when the target vehicle is driving away from the camera is recorded as the fourth time value. If the vehicle's driving direction is towards the camera, no recording is required.

[0075] In one embodiment of the present invention, identifying whether the target vehicle is traveling in the wrong direction based on the first transition time value, the second transition time value, the third transition time value, and the fourth time value includes:

[0076] Determine a first time difference between the second transition time value and the first transition time value; determine a second time difference between the fourth time value and the third transition time value; based on the first time difference and the second time difference, determine whether the target vehicle is traveling in the wrong direction.

[0077] The step of determining whether the target vehicle is traveling in the wrong direction based on the first time difference and the second time difference includes:

[0078] If the first time difference is greater than 0 and less than the first time threshold, and the second time difference is greater than 0 and less than the second time threshold, then the target vehicle is determined to be traveling in the wrong direction.

[0079] It should be noted that the first time threshold represents the preset time for the target vehicle to travel from the gate detection area to the control unit detection area; the second time threshold represents the preset time for the target vehicle to leave the control unit detection area and drive out of the vehicle identification area; the first time threshold and the second time threshold can be set according to the actual situation, and no specific restrictions are made here.

[0080] Specifically, when a vehicle exits the parking lot in the opposite direction at the entrance or enters the parking lot in the opposite direction at the exit, it first passes through the barrier gate detection area, then the control unit detection area, and finally the vehicle identification area. Therefore, in this embodiment, the first time difference is obtained by subtracting the second transition time value from the first transition time value, and the second time difference is obtained by subtracting the fourth time value from the third transition time value. Understandably, the calculation methods for the first and second time differences are as follows:

[0081] N1 = T2 - T1

[0082] N2 = T4 - T3

[0083] Where N1 represents the first time difference, N2 represents the second time difference, T1 represents the first transition time value, T2 represents the second transition time value, T3 represents the third transition time value, and T4 represents the fourth time value.

[0084] Furthermore, if the first time difference is greater than 0 and less than the first time threshold, and the second time difference is greater than 0 and less than the second time threshold, then the target vehicle is determined to be traveling in the wrong direction; otherwise, the target vehicle is determined not to be traveling in the wrong direction.

[0085] Furthermore, in this embodiment, the transition times of the detection signals from the controller's ground sensor and the barrier gate's ground sensor are updated in real time. Therefore, if a vehicle enters the parking lot normally from the entrance or lingers normally at the entrance, even if the third controller outputs a signal indicating that the vehicle is driving away from the camera, the transition times of the barrier gate's ground sensor and the controller's ground sensor will not meet the conditions that the first time difference is less than the first time threshold and the second time difference is less than the second time threshold. Therefore, a misjudgment of a reverse passage event will not occur.

[0086] This invention accurately determines whether a target vehicle is traveling in the wrong direction by combining a first time difference between a second transition time value and a first transition time value, and a second time difference between a fourth time value and a third transition time value, thereby improving the management order of the parking lot and reducing the losses of the parking lot management.

[0087] In one embodiment of the present invention, after determining that the target vehicle is traveling in the wrong direction, the method further includes:

[0088] If the third controller is an entrance controller, it determines that the target vehicle is exiting in the wrong direction and generates a wrong exit warning message to collect fees from the target vehicle; if the third controller is an exit controller, it determines that the target vehicle is entering in the wrong direction and generates an entry record for the target vehicle to manage its exit based on the entry record.

[0089] It should be noted that the type label of the third controller can be used to determine whether the target vehicle is exiting the parking lot in reverse or entering the parking lot in reverse. In other embodiments, the type label of the barrier gate ground sensor, the controller ground sensor, or the camera connected to the controller can also be used to determine whether the target vehicle is exiting the parking lot in reverse or entering the parking lot in reverse.

[0090] Specifically, if the third control unit is an entrance control unit, it determines that the target vehicle is exiting the parking lot in the wrong direction at the entrance, thus generating a reverse exit warning message. Further, based on the reverse exit warning message, the target vehicle is charged for unpaid parking fees. The collection process can be divided into the following steps: Since the third control unit has already identified the target vehicle's license plate number when the vehicle passes through the vehicle identification area, after determining that the target vehicle is exiting in the wrong direction, the exit time is determined, and the entry time associated with the license plate number is queried. Based on the entry and exit times, the outstanding amount of the target vehicle is calculated, and then a reverse exit warning message is generated based on the license plate number, entry time, exit time, and outstanding amount. Further, if the contact information of the target vehicle's owner can be obtained based on the license plate number, the reverse exit warning message is sent to the target vehicle's owner to collect the fees. This informs the target vehicle's owner that the parking lot is aware of their reverse exit and unpaid parking fees, and that failure to return and pay the fees will negatively impact their credit score.

[0091] Furthermore, if the third controller is an exit controller, it determines that the target vehicle is entering the parking lot from the opposite direction at the exit, and then determines the entry time of the target vehicle. Further, based on the entry time and the license plate number identified by the controller, an entry record of the target vehicle is generated. Thus, when the target vehicle exits, the entry record associated with the target vehicle can be correctly matched, and the exit control of the target vehicle can be performed, thereby realizing closed-loop processing of matching reverse exit events and reverse entry events.

[0092] This invention generates a reverse exit warning message when it is determined that the target vehicle is exiting in the wrong direction, thereby collecting payment from the target vehicle and preventing malicious toll evasion. Furthermore, when it is determined that the target vehicle is entering in the wrong direction, an entry record is generated for the target vehicle. This allows for querying the vehicle's entry record upon exit, enabling exit control of the target vehicle and improving parking lot management order while reducing losses for the parking lot management entity.
