[0044] With the rapid development of the economy, the number of cars in cities has increased dramatically. Due to the gradual development of the urban nature, the number of parking lots and parking spaces in cities can hardly keep up with the growth of vehicles, resulting in a prominent problem of difficulty in parking.

[0045] In order to improve the turnover rate of parking spaces, the commonly used technology is: generally, the first license plate recognition is performed to record the license plate when the vehicle enters the parking lot, and the second vehicle recognition is performed when the vehicle leaves the parking lot. The time of the two license plate recognitions is compared and then the charges are calculated; the exit of the parking lot is equipped with an antenna or a toll terminal equipped with a PSAM card, and the barrier is lifted to let the vehicle pass after the antenna or the toll terminal completes the collection.

[0046] However, the commonly used technologies currently have the following technical problems: The above methods need to be used in conjunction with closed parking lots, which restrict the entry and exit of vehicles and only allow them to leave after paying.

For the parking company administrator, you can assign permissions such as access to vehicle entry and exit records and fee management. For the system administrator, you can assign and manage the permissions of other users.

[0059] In one embodiment, the parking space information management module is used to build a real-time updated database of unattended parking spaces on public roads, support the query, modification and statistics of information such as parking space status (free, occupied), parking space number, etc., and provide parking lot managers with an intuitive view of parking space usage.

[0060] Specifically, the parking space information management module is also used to:

[0061] Collecting parking space usage information and updating the parking space usage status according to the usage information;

[0062] A parking space usage view is generated according to the usage status, and the usage view is transmitted to the user for the user to view.

[0063] After the parking space usage view is generated, the parking space usage view may be pushed to the user for viewing.

[0064] In one embodiment, the information recording module can use license plate recognition technology, combined with vehicle model and other information, to automatically capture the license plate information of the vehicle when it enters and exits the parking lot, record key data such as time and parking space number, and generate detailed entry and exit records to provide a basis for billing.

[0072] Reference Figure 3 , which shows a schematic diagram of the operation flow of an information publishing module provided by an embodiment of the present invention.

[0073] Specifically, it can automatically generate parking space full warnings, fee settlement notifications, system maintenance announcements and other content according to preset rules; in order to ensure the accuracy and appropriateness of the information, all notifications and announcements can go through relevant review processes before being published; set up scheduled tasks to automatically publish notifications and announcements as planned; determine the car owners who need to receive notifications based on vehicle entry and exit records, combined with vehicle identification technology; and use diversified intelligent notification services such as SMS, AI outbound calls, and WeChat public accounts to push information.

[0074] Reference Figure 4 , shows a schematic diagram of the operation flow of the intelligent billing module provided by an embodiment of the present invention.

[0075] Among them, as an example, the intelligent billing module can automatically calculate the parking fee based on factors such as the vehicle's stay time and parking space type, and provide a variety of payment methods (such as mobile payment, bank card payment) for car owners to choose from, to achieve convenient and fast fee settlement.

[0076] Specifically, the intelligent billing module is also used for:

[0077] When it is determined that the vehicle has left the parking space, the vehicle's stay time is calculated using the time the vehicle enters and exits the parking space, and the stay fee is calculated according to the stay time;

[0078] If it is determined that the user has bound a payment method in advance, settlement is completed using the bound payment method according to the stay fee;

[0079] If it is determined that the user has not bound a payment method in advance, multiple payment methods are displayed to the user, so that the user can select any payment method and make payment according to the stay fee.

[0080] In actual operation, the intelligent billing module can adopt high-performance license plate recognition frameworks such as HyperLPR3, combined with IoT and image recognition technology, to achieve multi-scenario adaptability and high recognition rate. The accuracy and robustness of license plate recognition are ensured through steps such as preprocessing images, locating license plate areas, segmenting characters, and recognizing characters.

[0081] By integrating various functional modules, a complete intelligent system is formed. Through rigorous testing, the stability, reliability and usability of the system are ensured, providing users with high-quality parking management services.

[0082] In this embodiment, the embodiment of the present invention provides a billing service system for public parking spaces, which has the beneficial effects of: the present invention can automatically monitor and bill unattended parking spaces on public roads, which can not only simplify the monitoring process and improve monitoring efficiency, but also reduce labor costs; in addition, the monitoring processing process is automatically executed by the system, which can reduce the probability of omissions and billing errors.

[0083] Reference Figure 2 , showing a flow chart of a public parking space charging method provided by an embodiment of the present invention.

[0084] In one embodiment, the method is applicable to the billing service system for public parking spaces as described in the above embodiment, wherein, as an example, the billing method for public parking spaces may include:

[0085] S11. When a vehicle enters a parking space, a high-definition camera of the parking space is used to collect a vehicle image and pre-process the vehicle image to obtain a processed image.

[0086] In one embodiment, a geomagnetic sensor, an infrared sensor or a camera may be set in the parking space to determine whether a vehicle enters the parking space. If a vehicle enters the parking space, a high-definition camera may be called to obtain an image of the vehicle. At the same time, the image of the vehicle may be preprocessed to obtain a processed image.

[0087] Preprocessing may include graying, denoising, contrast enhancement, etc., to improve image quality and reduce the difficulty of subsequent processing. Image segmentation technology is then used to separate the license plate area from the background of the load.

[0088] S12: using a license plate detection algorithm to identify a license plate area of ​​the vehicle image and scan the license plate area to obtain license plate characters.

[0089] In one embodiment, a license plate detection algorithm (e.g., a deep learning-based target detection algorithm) may be used to accurately determine the location of the license plate in the processed image and determine the boundary of the license plate area.

[0090] S13, performing character processing and feature extraction on the license plate characters in sequence to obtain the license plate number, wherein the character processing includes: grayscale processing, binarization processing and segmentation processing.

[0091] In one embodiment, a character segmentation algorithm can be used during segmentation to ensure that each character is accurately segmented and processed without interference from adjacent characters or background noise. In addition, OCR technology can be used to recognize the segmented characters one by one, or a high-performance license plate recognition framework such as HyperLPR3 can be used for recognition, or the characters of the license plate can be efficiently recognized through a built-in deep learning model.

[0092] In addition, according to the actual application situation, the mobile phone can continuously feedback data to optimize and adjust the license plate recognition algorithm to improve the recognition accuracy and robustness to adapt to more complex scenarios and license plate recognition needs under different optical coupling conditions.

[0093] S14. After the license plate number is bound to the vehicle, the length of stay of the vehicle is recorded, and a stay fee is calculated according to the length of stay.

[0094] In one embodiment, after the license plate number is bound to the current vehicle, the user can be identified based on the license plate number, and the vehicle's stay time can be recorded. When the vehicle is determined to have left, the total stay time of the vehicle is calculated, and finally the stay fee is calculated based on the stay time. Subsequently, the fee settlement notification can be pushed to the user through the official account, SMS, or AI outbound call, and the user can be prompted to pay.

[0095] Specifically, through binding as well as sensors and cameras, the position of the vehicle can be detected in real time, and the parking space number of the vehicle can be accurately located, so that even if the owner does not manually select a parking space, the specific location of the vehicle can be accurately known.

[0096] In this embodiment, the embodiment of the present invention provides a method for charging a public parking space, and its beneficial effect is that: when a vehicle enters a parking space, the present invention can use a high-definition camera of the parking space to collect a vehicle image and pre-process the vehicle image to obtain a processed image; extract the license plate number from the processed image; after binding the license plate number to the vehicle, record the length of time the vehicle stays, and calculate the stay fee according to the length of time. Through the above operation, it is possible to quickly and accurately determine whether the vehicle is parked in the parking space, and charge after determining that the vehicle is parked, so as to improve the accuracy of the calculation and reduce the error of the calculation.
