[0002] In modern parking lot management systems, vehicle identification technology is usually used to control vehicles entering and leaving the parking lot. When a car enters the parking lot, the identification device at the entrance will capture the vehicle's license plate information and record it in the database, marking it as an entry status and recording relevant information such as the entry time. When the vehicle leaves the parking lot, it will also be scanned at the exit, and the license plate will generally be identified again. The system calculates the parking time of the vehicle based on the entry record.

[0003] However, there is currently an abnormal situation where the car has successfully passed the exit scan test when leaving the parking lot, and the system determines that it can leave the parking lot, but the vehicle does not actually leave the parking lot, but returns to the parking lot to continue parking. Since the vehicle's return is not considered a new entry operation, there is no corresponding second entry record in the system. Therefore, when the vehicle leaves the parking lot again, the vehicle will be released directly due to the lack of entry records and the inability to calculate the parking time of the vehicle.

[0004] In view of this, we need a vehicle exit recognition method and system for parking lots to solve the above problems. Summary of the invention

In addition, the terms "one", "first", "second", "third", "fourth", "fifth", "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other. Example 1

[0025] like Figure 1 As shown, this embodiment provides a vehicle exit recognition method applied to a parking lot, wherein the method comprises: S10, obtaining the entry vehicle characteristic information of the target vehicle, wherein the entry vehicle characteristic information includes the entry time and license plate information of the target vehicle; Exemplarily, when the target vehicle enters the parking lot, the entry time and license plate information of the vehicle are obtained through relevant equipment at the entrance of the parking lot. The relevant equipment can be devices such as a camera combined with license plate recognition software and a time recording module. These information are stored in the entry database and serve as an important basis for matching and charging when the vehicle exits later. For example, when the target vehicle enters the parking lot at 10:00:00 on November 25, 2024, and the license plate is "Su E12345", the system will record this set of information as the entry vehicle characteristic information.

[0026] S20. When it is detected that there is a target vehicle in the first recognition area, recognize the exit vehicle characteristic information of the target vehicle. The exit vehicle characteristic information includes the exit time and license plate information of the target vehicle. When the target vehicle travels to the first recognition area at the exit of the parking lot, the detection equipment at the exit will recognize the exit time of the vehicle and reconfirm the license plate information. The detection equipment can be an image acquisition device such as a camera. This step ensures the consistency between the exiting vehicle and the entering vehicle and accurately records the specific time point of exit for subsequent calculation of the vehicle's parking time. For example, when the vehicle arrives at the first recognition area at the exit at 11:25:00 on November 25, 2024, the system recognizes the license plate as "Su E12345" and records this set of information as the exit vehicle characteristic information.

[0027] S30. Match the entry vehicle characteristic information with the exit vehicle characteristic information and obtain the exit vehicle information of the target vehicle. The system matches the entry vehicle characteristic information recorded at the time of entry with the exit vehicle characteristic information recognized at the time of exit. If the two match successfully, that is, the license plate information is the same, then further obtain the exit vehicle information of the vehicle, including but not limited to other relevant information such as the license plate number, body shape, and vehicle type of the vehicle.

[0028] S40. Based on the exit vehicle information, identify and extract the key feature area of the target vehicle, where the key feature area is the rear part area of the target vehicle. After identifying and obtaining the body shape of the vehicle based on the exit vehicle information, further extract the rear part area of the vehicle as the key feature area.

[0029] S50. Determine whether the key feature area exceeds the second recognition area. If it exceeds, obtain the vehicle parking time based on the entry vehicle characteristic information and the exit vehicle characteristic information and calculate the vehicle payment information. After the target vehicle pays successfully, it is released. For example, through image analysis technology or sensor detection, it is determined whether the key feature area, that is, the rear area of ​​the vehicle, exceeds the second identification area, which can be a specific release area range at the exit of the parking lot. If the rear of the vehicle exceeds the area, it means that the vehicle has basically completed the exit action. The system will perform basic subtraction calculations based on the entry time and exit time in the entry vehicle feature information and the exit vehicle feature information to obtain the vehicle's stay time. The vehicle payment information of the target vehicle is calculated based on the vehicle's stay time. When the system detects that the target vehicle has completed the payment, the target vehicle is released and allowed to leave the parking lot.

[0030] For example, the second recognition area is set to a range of 2 meters behind the exit barrier. When the rear area of ​​the vehicle exceeds the 2-meter range, the system detects that the vehicle has completed payment, and the barrier of the parking lot will automatically lift up to release the vehicle.

[0031] S60. Otherwise, the vehicle stay time is accumulated and the vehicle cumulative stay time is generated until it is detected that the key feature area of ​​the target vehicle exceeds the second identification area, and the vehicle payment information is calculated according to the vehicle cumulative stay time. The target vehicle is released after the payment is successful.

[0032] If the key feature area is detected, that is, the rear area of ​​the vehicle does not exceed the second identification area, it means that the vehicle has not actually left the parking lot, but has returned to the parking lot to continue parking, and may not have fully completed the exit process. Then the system will accumulate the stay time and generate the vehicle's cumulative stay time until it is detected that the key feature area of ​​the target vehicle exceeds the second identification area. The vehicle payment information will be calculated according to the vehicle's cumulative stay time, and the target vehicle will be released only after the payment is successfully made according to the payment information.

[0033] For example, the vehicle's entry time is 10:00:00, the exit time is 11:25:00, and the stay time is 1 hour and 25 minutes. However, the vehicle detects that the rear area of ​​the vehicle does not exceed the second recognition area, and the timing continues. At 12:25:00, the system detects that the key feature area of ​​the vehicle exceeds the second recognition area. The system then calculates the parking payment information according to the vehicle's cumulative stay time, which is 2 hours and 25 minutes. The target vehicle will be released only after it has successfully paid the fee according to the payment information.

[0034] Furthermore, the vehicle exit identification method specifically includes the following steps: Obtaining the entry vehicle appearance information of the target vehicle, wherein the entry vehicle appearance information includes the vehicle body color information and vehicle appearance information when the target vehicle enters the venue; When the target vehicle enters the parking lot, the appearance-related information of the vehicle is obtained at the entrance of the parking lot through relevant equipment, such as cameras or image acquisition equipment. This step can accurately identify the body color of the vehicle when it enters the parking lot, such as white, black, red, etc., and also capture the overall appearance of the vehicle, such as the model of the vehicle, the general outline of the vehicle and special logos.

[0035] A judgment is made based on the entering vehicle characteristic information and the entering vehicle appearance information to determine whether the entering vehicle characteristic information and the entering vehicle appearance information meet the preset vehicle characteristic information, wherein the preset vehicle characteristic information includes internal vehicle information, special vehicle information and temporary vehicle information.

[0036] If the determination result is internal vehicle information, where the internal vehicle information is an internal vehicle pre-stored in the system database, the internal vehicle is directly released; If the vehicle is judged to meet the relevant characteristics of internal vehicles pre-stored in the system database, it means that the vehicle belongs to the category of internal vehicles. The internal vehicle is usually a vehicle associated with the unit to which the parking lot belongs, which may be a company employee's official vehicle or an internal fixed vehicle. If the judgment result is an internal vehicle, the system can directly issue a release instruction, allowing the vehicle to enter or leave the parking lot smoothly without paying.

[0037] If the result of the determination is special vehicle information, where the special vehicle information is a special vehicle for performing tasks such as a police car, ambulance, or fire truck, the special vehicle will be released directly; When the judgment result shows that the vehicle belongs to special vehicles, the target vehicle may be a special vehicle on duty, such as a police car, ambulance, or fire truck. When the system identifies such special vehicles, it will immediately release them to ensure that they can pass through the parking lot quickly.

[0038] If the determination result is temporary vehicle information, where the internal vehicle information is a temporary vehicle not stored in the system database, the temporary vehicle will be released after the parking fee is charged.

[0039] If the vehicle is judged to be a temporary vehicle, that is, the vehicle is not stored in the system database and is an external temporary parking vehicle, the parking lot will charge the corresponding parking fee according to the established charging standards when the vehicle leaves the parking lot before releasing it. The parking lot will accurately calculate the parking time based on the entry and exit time of the temporary vehicle, and then determine the payment information.

[0040] Furthermore, the vehicle exit identification method specifically includes the following steps: Store the characteristic information and appearance information of the vehicles entering the venue to form an entry database; Store exit vehicle feature information, exit vehicle information and key feature information to form an exit database; The entry database and exit database are regularly deleted and updated every week.

[0041] In order to ensure the operation of parking lot entry and exit and the validity of data, the entry database and exit database will perform regular deletion and update operations every week. For example, when performing regular updates, the system will delete some data records that have expired or are no longer of reference value according to the set rules. For example, for vehicle records that have completed the exit process and have properly handled related fee settlement, information verification, etc., if their entry or exit time is more than one week away from the current time, then these records will be deleted from the corresponding database.

[0042] Furthermore, the method further comprises: Generate a normal signal based on the vehicle dwell time; Generate an abnormal signal based on the accumulated vehicle dwell time; Store normal signals and abnormal signals in the signal database.

[0043] Normal signals and abnormal signals are stored in a special signal database, which is used to centrally manage and archive the signal records of all vehicles for subsequent query, statistics and analysis.

[0044] Based on the signal database, when a normal signal is detected, it is sent to the display device in real time; When the system detects a normal signal in the signal database, it will send the signal to the display device in real time. The display device can be a monitoring screen in the parking lot management office. On the monitoring screen, the staff can see the information prompts of normal vehicle entry and exit of the parking lot, such as "the vehicle with license plate number "Su E12345" has left the parking lot", so that the staff can understand and monitor the daily operation of the parking lot in real time.

[0045] When an abnormal signal is detected, the abnormal signal is sent to the display device in real time and an early warning is issued.

[0046] If an abnormal signal is detected, the system will not only send the abnormal signal to the display device in real time, but also issue an early warning at the same time. The display device will display prompt information such as "The vehicle with license plate number "Su E12345" has left the parking lot abnormally" to remind the parking lot manager to deal with the abnormal situation in time. Secondly, the early warning method can be in various forms, such as sounding an alarm in the parking lot management office and pushing an abnormal notification message to the manager's mobile phone or computer terminal at the same time, so that the manager can be informed of the abnormal situation at the first time and take corresponding measures no matter where he is, so as to contact the car owner to inquire about the relevant situation and ensure that the normal operation order of the parking lot is not affected.

[0047] The present application matches the entry vehicle characteristic information with the exit vehicle characteristic information, and obtains the exit vehicle information of the target vehicle; performs identification based on the exit vehicle information, and extracts the key characteristic area of ​​the target vehicle, wherein the key characteristic area is the rear area of ​​the target vehicle; determines whether the key characteristic area exceeds the second identification area, and if so, obtains the vehicle residence time and calculates the vehicle payment information based on the entry vehicle characteristic information and the exit vehicle characteristic information, and releases the target vehicle after successful payment; otherwise, accumulates the vehicle residence time and generates the vehicle cumulative residence time, until it is detected that the key characteristic area of ​​the target vehicle exceeds the second identification area, calculates the vehicle payment information according to the vehicle cumulative residence time, and releases the target vehicle after successful payment, thereby achieving the better effect of being able to accurately identify the vehicle exit and not allowing the vehicle to be directly released due to lack of entry record, and solves the problem that the existing system cannot accurately identify the vehicle exit, resulting in the vehicle being directly released due to lack of entry record.
