Referring to fig. 2, fig. 2 is a flowchart illustrating a parking lot control method according to a first embodiment of the present invention.

In the embodiment of the invention, the parking lot control method is applied to a parking lot control system, the parking lot control system comprises a plurality of entrance license plate recognition instruments, and the parking lot control method comprises the following steps:

step S10, when detecting information that a vehicle enters an entrance of a parking lot, obtaining a plurality of first license plate pictures of the vehicle through a plurality of entrance license plate recognition instruments respectively;

in the embodiment of the invention, the parking lot control method is applied to a parking lot control system, the parking lot control system comprises a plurality of entrance license plate recognition instruments, and the entrance license plate recognition instruments can be arranged at different positions of an entrance of a parking lot, so that the vehicle can be shot from a plurality of directions, and the condition that when the vehicle enters the parking lot at different entrance angles in the prior art, a single license plate recognition instrument cannot acquire a license plate picture sometimes to cause that the vehicle cannot enter the parking lot can be avoided.

In addition, in the embodiment of the invention, a ground induction coil can be arranged at the entrance of the parking lot and is used for judging whether a vehicle enters the entrance of the parking lot, and when the information that the vehicle enters the entrance of the parking lot is detected, a plurality of first license plate pictures of the vehicle are obtained through a plurality of entrance license plate recognition instruments. Certainly, in a specific embodiment, an image receiving device such as a camera may be further used to obtain a license plate picture of a vehicle at an entrance of a parking lot.

Step S20, identifying a plurality of corresponding first license plate information according to the plurality of first license plate pictures;

and then, identifying a plurality of corresponding first license plate information according to the obtained first license plate pictures. The first license plate information may include a license plate number and a vehicle approach time. Specifically, the approach time may be the time when the first license plate picture is obtained, and the license plate number identification process may include: firstly, positioning a license plate. Firstly, carrying out large-scale related search on an acquired vehicle image, finding a plurality of areas which accord with the vehicle license plate characteristics as candidate areas, then further analyzing and judging the candidate areas, finally selecting an optimal area as a license plate area, and separating the optimal area from the image. And secondly, segmenting license plate characters. And after the license plate region is positioned, the license plate region is divided into single characters, and then recognition is carried out. Character segmentation generally employs a vertical projection method. Since the projection of a character in the vertical direction necessarily takes the vicinity of a local minimum at a gap between or within characters, and this position should satisfy the character writing format of the license plate, the character, the size restriction, and some other conditions. The vertical projection method has a good effect on character segmentation in the vehicle image in a complex environment. And thirdly, recognizing characters of the license plate. The license plate character recognition mainly comprises a template matching algorithm and an artificial neural network algorithm. Based on a template matching algorithm, firstly, the segmented characters are binarized and the size of the segmented characters is scaled to be the size of a template in a character database, then the segmented characters are matched with all the templates, and the best matching is selected as a result. There are two types of algorithms based on artificial neural networks: one is to extract the character and then train the neural network distributor with the obtained character; the other method is to directly input the image into the network, and the network automatically realizes the feature extraction until the result is identified. After the corresponding first license plate information is identified, the first license plate pictures and the first license plate information are stored in a correlated mode.

Step S30, when a first payment request is received, determining whether second license plate information input by a user in the first payment request is matched with at least one of a plurality of first license plate information;

step S40, if not, a plurality of first license plate pictures corresponding to a plurality of first license plate information similar to the second license plate information are called and sent to a user terminal;

and step S50, receiving a first confirmation result fed back by the user terminal, and generating corresponding payment information according to the first confirmation result.

In the embodiment of the invention, when a first payment request triggered by a user through a user terminal is received, second license plate information (namely, vehicle license plate numbers) input by the user is searched in a system, whether the second license plate information is matched with at least one of a plurality of pieces of first license plate information is determined, and whether the license plate numbers identical to the second license plate information exist in the plurality of pieces of first license plate information is determined. When the parking fee is matched with at least one of the plurality of first license plate information, the payment information can be normally generated according to the entrance time and the payment initiating time (or the current time) in the first license plate information, so that the user can normally pay the parking fee. When the first license plate information is not matched with the plurality of first license plate information, the first license plate information close to the license plate number input by the user can be searched, for example, the first license plate information with only one character inconsistent is extracted, the corresponding first license plate picture is taken out and sent to the user terminal, the user can confirm the correct license plate picture, the confirmation result is fed back to the system, and therefore the system obtains the entrance time of the vehicle according to the correct first license plate picture, and normally generates payment information according to the payment initiating time or the current time so that the user can normally pay the parking fee. Meanwhile, the system can automatically correct the corresponding first license plate information with wrong identification according to the second license plate information, namely the correct license plate number.

Specifically, the user can use intelligent terminal to pay through APP or public number payment, or pay through the two-dimensional code of paying of scanning setting in the parking lot, and wherein, the intelligent terminal for the scanning can be the cell-phone, also can be other smart machines such as panel computer. For example, after a user scans a payment two-dimensional code arranged in a parking lot through a mobile phone, a license plate number input interface is displayed in the mobile phone interface to prompt the user to input a license plate number of a vehicle, namely second license plate information, so that a first payment request is initiated. And when the first license plate information is matched with any one of the first license plate information, generating corresponding payment information according to the first license plate information, and correcting corresponding other wrong first license plate information. When the first license plate information does not exist, searching first license plate information similar to the license plate number input by the user, such as the first license plate information with only one character inconsistent, calling out the corresponding first license plate picture and sending the first license plate picture to the user terminal, enabling the user to identify the correct license plate picture, and feeding back the confirmation result to the system, so that the system obtains the entrance time of the vehicle according to the correct first license plate picture, normally generates payment information according to the payment initiating time or the current time, and automatically corrects the corresponding first license plate information with wrong recognition. When the payment information is generated, the payment information to be paid is sent to the user terminal, the user is prompted to pay the parking fee, the payment mode can comprise a payment treasure, a WeChat, a Unionpay and the like, and the user can select a proper mode to pay the parking fee according to actual conditions.

In addition, it should be noted that, in the specific embodiment, when the user pays by scanning the payment two-dimensional code arranged at the exit of the parking lot, when the payment operation is completed, the system can control the opening of the barrier gate at the exit of the parking lot, so that the vehicle can directly leave the parking lot.

The invention provides a parking lot control method. The parking lot control method is applied to a parking lot control system, the parking lot control system comprises a plurality of entrance license plate recognition instruments, and the parking lot control method comprises the following steps: when detecting information that a vehicle enters an entrance of a parking lot, respectively obtaining a plurality of first license plate pictures of the vehicle through a plurality of entrance license plate recognition instruments; identifying a plurality of corresponding first license plate information according to the plurality of first license plate pictures; when a first payment request is received, determining whether second license plate information input by a user in the first payment request is matched with at least one of a plurality of first license plate information; if not, calling a plurality of first license plate pictures corresponding to a plurality of first license plate information similar to the second license plate information and sending the first license plate pictures to the user terminal; and receiving a first confirmation result fed back by the user terminal, and generating corresponding payment information according to the first confirmation result. In this way, because the parking lot control system comprises the plurality of entrance license plate recognition instruments, when the information that the vehicle enters the entrance of the parking lot is detected, the vehicle can be shot from a plurality of directions, so that a plurality of first license plate pictures are obtained, and then the corresponding first license plate information is recognized according to the first license plate pictures, so that the situation that when the vehicle enters the parking lot at different entrance angles in the prior art, a single license plate recognition instrument cannot acquire the license plate pictures sometimes can be avoided. And then when a first payment request triggered by a user is received, determining whether second license plate information input by the user in the first payment request is matched with at least one of the plurality of first license plate information, and when the matched first license plate information exists, generating corresponding payment information according to the first license plate information. When the first license plate information is not matched, the first license plate pictures corresponding to the first license plate information close to the second license plate information are called and sent to the user terminal, so that the user can confirm the correct license plate picture, corresponding payment information is normally generated according to the correct license plate picture, the user can quickly finish payment, and then normally goes out of the parking lot, and the condition that the user cannot normally finish payment and cannot go out of the parking lot when the license plate is identified incorrectly in the prior art can be avoided, therefore, the parking lot access control efficiency can be effectively improved.

In addition, in the embodiment of the present invention, a ground sensing coil may be further disposed at the exit of the parking lot, and is configured to determine whether a vehicle exits the exit of the parking lot, and when information that the vehicle exits the exit of the parking lot is detected, a plurality of third license plate pictures of the vehicle are obtained through a plurality of exit license plate recognition apparatuses, so as to obtain a plurality of third license plate information, where the third license plate information may include a license plate number and a vehicle departure time. Certainly, in a specific embodiment, an image receiving device such as a camera may be further used to obtain a license plate picture of a vehicle at an exit of the parking lot, and then a plurality of pieces of corresponding third license plate information are obtained through the recognition system.

Step S70, determining whether a plurality of third license plate information matches at least one of a plurality of first license plate information and the second license plate information;

step S81, if yes, determining whether the vehicle has finished payment operation;

step S82, if not, a plurality of first license plate pictures corresponding to a plurality of first license plate information or second license plate information which are similar to the third license plate information are called and sent to the user terminal, and whether the vehicle finishes the payment operation is determined according to a second confirmation result fed back by the user terminal;

and step S90, when the vehicle finishes the payment operation, controlling the barrier gate of the parking lot exit to open.

When the plurality of third license plate information is obtained, it is determined whether any of the plurality of third license plate information matches at least one of the plurality of first license plate information and the second license plate information.

When any one of the plurality of third license plate information is matched with any one of the plurality of first license plate information and second license plate information, whether the vehicle finishes the payment operation is further determined. And if the system inquires the corresponding information of successful payment, controlling the opening of a barrier gate at the exit of the parking lot to enable the vehicle to normally go out of the parking lot. In the embodiment, the recognized third license plate information is matched with any one of the first license plate information and the second license plate information only and can be normally discharged when payment is finished, and the matching rate of the license plate information is increased by the arrangement of the entrance license plate recognition instruments and the exit license plate recognition instruments, so that the control efficiency of the parking lot is improved. In addition, when the system does not inquire the corresponding information of successful payment, the user is prompted to pay, at the moment, the corresponding entrance time can be directly obtained according to the first license plate information corresponding to the third license plate information, the corresponding payment information is generated according to the exit time or the current time in the third license plate information, the user can use the intelligent terminal to complete payment operation through APP or public number payment or through scanning the payment two-dimensional code arranged at the exit of the parking lot, and at the moment, the barrier gate at the exit of the parking lot is controlled to be opened, so that the vehicle normally exits.

When any one of the third license plate information is not matched with the first license plate information and the second license plate information, prompting a user that no corresponding license plate information exists and prompting the user to use the intelligent terminal to confirm the license plate information, wherein the user can use the intelligent terminal to confirm through an APP (application), a public number or a two-dimensional code arranged at an exit of the parking lot by scanning; when the payment record corresponding to the license plate number is not inquired, searching first license plate information similar to the license plate number, such as the first license plate information with only one character inconsistent, calling out a corresponding first license plate picture and sending the first license plate picture to a user terminal, enabling a user to identify a correct license plate picture, feeding back a confirmation result to a system, inquiring whether the vehicle corresponding to the correct license plate picture completes the payment operation or not by the system, and controlling a barrier gate at an outlet of the parking lot to be opened when the related payment record is inquired, namely the vehicle completes the payment operation, so that the vehicle normally goes out of the parking lot; when the vehicle does not finish the payment operation, the system obtains the entrance time of the vehicle according to the correct first license plate picture, normally generates payment information according to the current time, and controls the opening of the barrier gate at the exit of the parking lot to enable the vehicle to normally leave the parking lot after the user finishes the payment operation.

It should be noted that, in an embodiment, the parking lot system may include an exit license plate recognition unit, so that when information that the vehicle exits the exit of the parking lot is detected, a third license plate picture of the vehicle is obtained through the exit license plate recognition unit, and it is determined whether the third license plate picture matches with at least one of the plurality of first license plate information and the plurality of second license plate information. The subsequent steps are similar to those in the above embodiments, and are not described herein.

In addition, it should be noted that when it is detected that the vehicle has completed the payment operation, it is also necessary to determine whether the time for completing the payment operation is within the preset time range, and when the time for completing the payment operation is not within the preset time range, the system can prompt the user to continue to pay, and generate corresponding payment information according to the time for completing the payment operation and the current vehicle, and when the user can use the intelligent terminal to complete the payment operation through APP or public number, or scan the payment two-dimensional code set at the parking lot exit, the barrier gate at the parking lot exit is controlled to be opened, so that the vehicle normally comes out of the parking lot.
