Description

Technical Field

[0001] The present application relates to the technical field of parking management, and in particular to a parking lot payment method and device based on license plate recognition. Background Art

[0002] Parking lots can provide safe and reasonable parking spaces for cars. With the increasing number of cars, the traditional manual parking lot payment method can no longer meet the current car needs and needs to be automated and intelligently transformed.

[0003] In the existing payment method of smart parking lots, a time-based charging system is usually adopted for payment, that is, the ETC system is combined to identify the license plate number to calculate the parking time and make automatic payment. However, in the implementation process of the existing payment method, it can be found that when the license plate has abnormal conditions, such as stains, deformation, scratches, unreasonable obstruction or alteration, the incorrect recognition and matching of the license plate at the entrance and exit of the parking lot will cause the vehicle to be unable to enter and exit normally, affecting efficiency. For example, when the license plate is normal when the vehicle enters the parking lot, but when the license plate is abnormal due to scratches, stains, etc. in the parking lot, the license plate when entering the parking lot and when leaving the parking lot will be inconsistent, resulting in the inability to generate payment records normally and the exit gate will not open, and it will be impossible to drive out normally. Therefore, how to perform reasonable matching after identifying the license plate to further improve the payment efficiency is an urgent problem to be solved in the prior art. Summary of the invention

[0043] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below in conjunction with the accompanying drawings are exemplary and are only used to explain some embodiments of the present application, and should not be construed as limitations on the embodiments of the present application. Based on the embodiments shown in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0044] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, unless otherwise clearly and specifically defined, "multiple" and "several" mean two or more.

[0045] In the existing parking payment method, the time-based charging system is usually used for payment, that is, the ETC system is combined to identify the license plate number to calculate the parking time and automatically pay the fee. However, in the implementation of the existing payment method, it can be found that when the license plate has abnormal conditions, such as stains, deformation, scratches, unreasonable obstruction or alteration, the incorrect recognition and matching of the license plate at the entrance and exit of the parking lot will cause the payment record to be unable to be generated normally, and the vehicle cannot enter and exit normally, affecting the payment efficiency and traffic efficiency. Therefore, how to perform reasonable matching after identifying the license plate to further improve the payment efficiency is an urgent problem to be solved in the existing technology.

[0046] Based on the above technical background, please refer to Figure 1 The embodiment of the present application provides a parking fee payment method based on license plate recognition, including steps S101 to S104, each of which is as follows:

[0047] Step S101: Identify the front license plate of the current vehicle to be paid and obtain the first license plate information.

[0048] In certain embodiments of the present application, it further includes:

[0049] Recognize the front license plate of the current vehicle to be parked to obtain a first recognition result;

[0050] If the first recognition result is a failure, an abnormal recognition alarm is broadcast to the current vehicle, and a successful recognition prompt is broadcast in response to a return instruction of the current vehicle to the abnormal recognition alarm.

[0051] Consider recognizing the front license plate of the current vehicle to be parked and broadcasting a recognition abnormality alarm when recognition fails. This is because the failure to recognize the front license plate represents stains, deformation, scratches, unreasonable obstruction or alteration, which results in the inability to pay the fee. It is necessary to broadcast a recognition abnormality alarm to guide the owner of the current vehicle to check and process it, so as to re-recognize successfully in response to the feedback instruction of the recognition abnormality alarm and broadcast a recognition success prompt.

[0052] In certain embodiments of the present application, it further includes:

[0053] Identify the front license plate and the rear license plate of the current vehicle to be parked, and obtain the front license plate information and the rear license plate information;

[0054] If the front license plate information is consistent with the rear license plate information, the front license plate information is stored in the parking lot license plate recognition record, and a first pass prompt is broadcast to the current vehicle;

[0055] If the front license plate information and the rear license plate information are inconsistent, abnormal license plate information is obtained based on the front license plate information and the rear license plate information, and the abnormal license plate information is stored in the parking lot license plate abnormality record. At the same time, an abnormal passage alarm is broadcast to the current vehicle, and a second passage prompt is broadcast in response to the feedback instruction of the current vehicle to the abnormal passage alarm.

[0056] In certain embodiments of the present application, obtaining abnormal license plate information according to the front license plate information and the rear license plate information specifically includes:

[0057] The front license plate information and the rear license plate information are uploaded to the parking lot platform to obtain feedback information from the parking lot platform, and abnormal license plate information is obtained according to the feedback information.

[0058] Consider identifying the front and rear license plates of the current vehicle to be parked to obtain the front and rear license plate information, and compare whether the front and rear license plate information are consistent to take different operations. This is because when the front and rear license plates are consistent, it means that the license plate of the current vehicle is normal and the front and rear license plate information can be stored normally. Therefore, the passage prompt can be broadcast without additional operation; when the front and rear license plates are inconsistent, it means that one of the front and rear license plates of the current vehicle has stains, deformation, scratches, unreasonable obstruction or alteration, which may affect the subsequent vehicle payment. Therefore, it cannot be stored in the parking lot license plate recognition record. The abnormal license plate information should be stored in the parking lot license plate abnormality record, and a passage abnormality broadcast should be sent to remind the owner of the current vehicle to check and handle it, so as to reduce or eliminate the impact on subsequent vehicle payment.

[0059] The present application obtains the front license plate information and the rear license plate information by respectively identifying the front and rear license plates of the current parked vehicle, and then, based on the comparison results of the front license plate information and the rear license plate information, selects the front license plate information to be stored in the parking lot license plate recognition record and broadcasts the first pass prompt when they are consistent. The license plate information of the current vehicle under normal circumstances can be archived and retained for continued use, thereby improving the matching efficiency during subsequent payment. Or, when they are inconsistent, abnormal license plate information is obtained based on the front license plate information and the rear license plate information and stored in the parking lot license plate abnormality record and broadcast an abnormal passage alarm, and then a second pass prompt is broadcast in response to the feedback instruction of the abnormal passage alarm of the current vehicle. When a license plate of the current vehicle is abnormal, the abnormal license plate information can be archived and retained for continued use, thereby improving the matching efficiency during subsequent payment.

[0060] Step S102: Match the first license plate information with the parking lot license plate recognition record to obtain a first matching result.

[0061] Step S103: If the first matching result is not empty, the first license plate information is matched with the parking lot license plate abnormality record to obtain a second matching result, and based on the second matching result, payment information is generated for the current vehicle to pay.

[0062] In certain embodiments of the present application, generating payment information for the current vehicle to pay according to the second matching result specifically includes:

[0063] If the second matching result is empty, payment information is generated according to the parking lot license plate recognition record and the first license plate information for the current vehicle to pay.

[0064] When the second matching result is empty, the present application generates payment information based on the parking lot license plate recognition record and the first license plate information for the current vehicle to pay. When there is an recognition record for the current vehicle's license plate and there is no abnormal record, it can simply and directly perform billing and generate payment information, thereby improving payment efficiency.

[0065] In certain embodiments of the present application, generating payment information for the current vehicle to pay according to the second matching result specifically includes:

[0066] If the second matching result is not empty, the second abnormal alarm is broadcast to the current vehicle, and payment information is generated based on the current vehicle's feedback instructions for the second plan for the current vehicle to pay; wherein, the second plan is generated based on the second matching result and the first license plate information and sent to the current vehicle, and the feedback instructions of the second plan are generated based on the second abnormal alarm.

[0067] In certain embodiments of the present application, the second solution is generated based on the second matching result and the first license plate information and sent to the current vehicle, specifically:

[0068] Obtaining a license plate abnormal parking record according to the second matching result and the first license plate information;

[0069] According to the abnormal parking record of the license plate, a second plan is generated and sent to the current vehicle.

[0070] This application first broadcasts the second abnormal alarm when the second matching result is not empty, and generates payment information for the current vehicle to pay based on the feedback instructions of the second plan of the current vehicle. When there is an identification record of the license plate of the current vehicle but there is an abnormal record, the second plan and then the payment information can be generated in time based on the second matching result and the first license plate information, thereby achieving a reasonable match of the license plate when paying, thereby improving payment efficiency.

[0071] Step S104: If the first matching result is empty, payment information is generated according to a first solution for the current vehicle to pay; wherein the first solution is generated according to the characteristics of the current vehicle and sent to the current vehicle.

[0072] In certain embodiments of the present application, generating payment information according to the first solution for the current vehicle to pay the fee specifically includes:

[0073] A first abnormal alarm is broadcast to the current vehicle, and payment information is generated in response to a feedback instruction of the current vehicle to the first scheme for the current vehicle to pay the fee; wherein the feedback instruction of the first scheme is generated based on the first abnormal alarm.

[0074] In certain embodiments of the present application, the first solution is generated according to the characteristics of the current vehicle and sent to the current vehicle, specifically:

[0075] According to the body image of the current vehicle, the characteristics of the current vehicle are obtained;

[0076] Based on the characteristics of the current vehicle and the first license plate information, according to a similarity matching algorithm, a parking record with the highest similarity is matched in the parking lot platform;

[0077] The first plan is generated according to the parking record and sent to the current vehicle.

[0078] In certain embodiments of the present application, the similarity matching algorithm includes but is not limited to a cosine similarity algorithm, a PSNR algorithm, a structural similarity (SSIM) algorithm, and a mean hash algorithm.

[0079] When the first matching result is empty, the present application first broadcasts the first abnormal alarm to the current vehicle, and then generates payment information in response to the current vehicle's feedback instruction for the first plan for the current vehicle to pay. When there is no recognition record for the license plate of the current vehicle, the first plan can be generated in time according to the characteristics of the current vehicle and then the payment information can be generated. The payment efficiency can be improved by processing the matching results of the license plate recognition under different conditions.

[0080] Compared with the prior art, the present application identifies the front license plate of the current vehicle to be paid, and then matches it with the parking lot license plate recognition record to obtain a first matching result, and then selects different payment methods according to the first matching result: when the first matching result is not empty, it matches the parking lot license plate abnormality record to obtain a second matching result, and generates payment information for the current vehicle to pay according to the second matching result; when the first matching result is empty, it generates a first solution according to the characteristics of the current vehicle and then generates payment information for the current vehicle to pay. Compared with the prior art, which cannot generate payment information normally after a license plate recognition error, the present application matches the license plate by combining license plate recognition with conditional branching, and selects different payment methods for different matching results. It can reasonably match the identified license plate, and then select an appropriate payment method, thereby improving payment efficiency.
