Description
Technical Field
The invention relates to a camera, in particular to camera fault judgment based on a license plate recognition method.
Background
The problem of license plate recognition through a camera is that license plate recognition errors can occur, and the errors can be recognized into other license plate numbers or no license plate numbers.
When a wrong identification is made that there is no license plate, parking lots often require a vehicle owner to enter the parking lot by scanning a code. A charging and passing method for a unlicensed vehicle in a parking lot (CN 112614242A) discloses various technical embodiments of how to scan codes to enter the parking lot when the unlicensed vehicle is identified.
Similarly, when no license plate number is erroneously identified and no corresponding order is available, the parking lot may require the owner to drive away from the parking lot. A vehicle passing processing method, a vehicle passing processing device and a storage medium (CN 108335388B) disclose a technical scheme of how to scan codes for leaving a field by exit license plate recognition errors.
In the prior art, the meaning of license plate recognition is that the entrance or the exit is determined to have a vehicle waiting through the license plate recognition. This is the basis for accepting the code scan by the owner (on-site). Otherwise, the car owner stores the two-dimensional code through (photographing), and the code is remotely scanned, so that the car can be wrongly released, and the management of the car is interfered.
Disclosure of Invention
The license plate is identified through the camera, when the returned result of the license plate identification is a license-free vehicle, the code scanning by the vehicle owner is required, and when the result is not returned, the code scanning by the vehicle owner is not necessarily required, otherwise, the vehicle is always in a waiting state. The technical problems corresponding to the method are as follows: the failure to return the license plate recognition result may be caused by a failure of the camera, so that whether the camera fails or not needs to be judged.
Namely, according to the prior art, the license plate recognition result cannot be obtained through license plate recognition, then the code scanning of the owner is received, and the license plate recognition result cannot be obtained under the condition that the camera fails, so that the system cannot always receive the code scanning information of the owner.
However, the license plate recognition result is not considered, namely whether the camera is in failure or not is judged, the two-dimensional code is accepted as long as the vehicle owner scans the code, the vehicle owner cannot distinguish the two-dimensional code stored by (photographing) the vehicle owner, the code is scanned remotely, so that a gateway corresponding to the code is opened, for example, at an entrance, the patent technology CN112614242A may add a situation that a vehicle without a license plate enters a parking lot for recording, at an exit, the patent technology CN108335388B may appear, and the system for misleading the license plate number of the vehicle which just enters the vehicle by scanning the code inputs the license plate number freely releases the vehicle with another license plate number which is charged.
The camera failure means that a license plate recognition result cannot be returned. However, when the license plate recognition result is not returned, there may be no vehicle needing to be recognized, and there may be a vehicle needing to be recognized, the former is normal, and the latter is a camera failure. Or, in other words, when a fault occurs, the camera itself cannot send fault information that it has failed to the system. That is, even if it is known that the license plate recognition result is not returned, the system itself cannot determine whether the camera is faulty.
Therefore, the invention provides a method for judging faults of a license plate recognition camera, which adopts the technical scheme that:
the system comprises a camera, a barrier gate, a display device, a two-dimensional code, a control device, a mobile phone and a server; the two-dimension code is static, and the code scanning is associated with the barrier gate; the camera has a license plate recognition function; the camera, the barrier gate and the display device are controlled by the control device; the control device is connected with the server through the Internet; the mobile phone is provided with a code scanning program;
a method for judging faults of a license plate recognition camera comprises the following steps:
(1) the mobile phone scans the static two-dimensional code;
(2) the control device acquires the identifier sent by the mobile phone code scanning from the server and/or acquires a mark set by the server according to the mobile phone code scanning;
(3) the control device inquires that the license plate recognition result is not returned by the camera;
(4) acquiring the identifier sent by the mobile phone and/or the mark set by the server according to the step (2), meanwhile, inquiring that no license plate recognition result is returned according to the step (3), and displaying the verification characters generated in real time or at regular time on a display device by a control device; inputting the verification character by the mobile phone, interacting the verification character to the server, and acquiring the verification character by the control device; if the control device compares the verification characters, the barrier is opened and processed or the barrier is opened after the verification characters are matched, otherwise, the mobile phone code scanning process is ignored;
in the above steps, the execution timing of step (2) and step (3) can be exchanged, and step (1) is independent of step (2) and step (3).
The marker may be a timestamp, a change in which indicates that a second scan has occurred.
And (4) if the license plate identification result inquired in the step (3) is not returned, the camera fault or the identity fault is indicated.
It is noted that the above step numbering is for ease of description and the logic performed is in accordance with the rationality of the method itself.
In the technical scheme of the invention, the display device displays the verification characters generated in real time or at regular time on the display device, and the mobile phone inputs the verification characters, and the verification characters can be correspondingly replaced by the hot spot identification device, the hot spot identification generated and the mobile phone detection hot spot identification. And the verification character or the hot spot identification is arbitrary, and the arbitrary is not regular.
It should be particularly noted that the technical solution of the present invention does not consider the situation that the license plate number is obtained by license plate recognition. And the license plate number can be obtained by license plate recognition, and the condition that the camera works normally is indicated. This is not discussed in the present invention.
In the technical scheme of the invention, the fact that the two-dimensional code is static means that the two-dimensional code is posted on the site, can be stored by a vehicle owner (photographing), and can be remotely scanned.
In the technical scheme of the invention, the verification character is a character which can be input on the mobile phone, and can also be a recognizable code which is dynamically displayed and is recognized by scanning a code, such as a two-dimensional code, of the mobile phone. This dynamically displayed recognizable code is emphasized on "dynamic", since the statically displayed code can also be stored (by taking a picture) and used remotely, again causing interference with vehicle management.
In the technical solution of the present invention, the "processing" in step (4) may be order generation, charging, fee deduction, and the like according to the identifier and/or the mark. This is common general knowledge to a person skilled in the art.
For those skilled in the art, it is common practice that a camera is used for license plate recognition, a barrier gate is used for releasing vehicles, and a two-dimensional code can be connected with a server through code scanning.
In particular, the barrier can be represented as a traffic light and has already been applied to occasions such as self-service car washing.
On the other hand, the code scanning program installed in the mobile phone can be developed by the system operation manager or a third party. Through code scanning, the identification information such as the identity and account of the vehicle owner can be interacted with the server, which is also the common practice of the person skilled in the art. For example, the technical solution of the present invention is "a mobile phone code scanning and sending identifier", and the actual implementation is that the WeChat sends the openID corresponding to the registered mobile phone to the server pointed by the two-dimensional code website.
In the technical scheme of the invention, the mark set by the server according to the mobile phone code scanning is acquired, wherein the mark can be related to or unrelated to the mark sent by the mobile phone code scanning. The "flag" may be a timestamp that serves to inform the control device that an owner code scan has occurred or that a code scan has again occurred.
The invention has the beneficial technical effects that:
can break down at the camera, when leading to the license plate recognition result not to carry out any return, also can accept the car owner and sweep the sign indicating number, normally manage the vehicle and drive in and roll out, avoided no matter whether the camera breaks down, as long as the car owner sweeps the sign indicating number and just accepts for the car owner can (shoot) save the two-dimensional code, and then long-range sweep the sign indicating number, and cause the interference to vehicle management.
If the camera is in fault, the vehicle owner can accept the code scanning only, so that the vehicle can be identified as a vehicle with a license plate through the license plate, the license plate number is input in a remote code scanning mode at an exit, the vehicle can drive away within the specified free time, and the vehicle still stays in a parking lot actually. And then, when the vehicle is driven away again, the corresponding order is not available in the parking lot, and the vehicle can only be processed according to the exception. This is one of the ways in which the management of the vehicle is disturbed.
The control device displays the verification characters generated in real time or at regular time on the display device; inputting the verification character by the mobile phone, interacting the verification character to the server, and acquiring the verification character by the control device; if the verification characters are matched, the control device opens the barrier and processes the verification characters according to the identification or opens the barrier after the verification characters are processed according to the identification, otherwise, the mobile phone code scanning is ignored, and the interference on vehicle management caused by remote code scanning of a code scanner can be eliminated. The "timing" refers to a time interval, relative, that produces the validation characters, consistent with the purpose of producing the validation characters in real time, i.e., preventing (photo) storage for remote input.
The invention has the advantages that the use occasions are not possible many, and the invention belongs to an emergency mechanism when a camera breaks down. This is the basis for implementing unattended operation. If the emergency mechanism is not provided, once the camera fails, no result is returned in the license plate recognition, and the patent technologies CN112614242A and CN108335388B and the like can not always receive the code scanning information of the vehicle owner. It should be noted that, the camera is shifted, the angle is adjusted, and the license plate cannot be recognized normally, which is considered that the camera fails, or that the license plate is recognized abnormally due to the angle or speed of the vehicle driving into or out of the parking lot, which is also considered that the camera fails. Even the parking area can not install the camera by purpose to reach the purpose of protection owner privacy, this is also normal, belongs to the range of application that the camera trouble takes place.
Detailed Description
Taking a parking lot entrance as an example, after a camera fails, the license plate recognition does not return any result, a vehicle owner sends a WeChat openID to a server by using a mobile phone WeChat scanning code, the openID is used as an identifier of the mobile phone scanning code, a control device of the parking lot is connected with the server to obtain the openID, and the control device generates a verification character '123456' in real time and displays the character on a display device to prompt the vehicle owner to input; after the car owner inputs '123456', the control device compares the verification characters, if the verification characters are matched, the barrier is opened to allow the car to enter, and meanwhile, a license-free car entrance record is generated.
When the car owner sweeps the sign indicating number and sends little letter openID, the server can also generate the timestamp, has swept the sign indicating number as the car owner, waits for a period of time after, if the banister does not have the action, the sign indicating number can be swept once more to the car owner, resets the timestamp, sweeps the sign that the sign indicating number set once more according to this cell-phone as the server. In this way, the control device can generate the authentication character again and display it on the display device. Thereafter, the verification process is repeated.
When the camera fails at the entrance of the parking lot, for the vehicle with the license plate, the vehicle owner can input the license plate number simultaneously when using the mobile phone WeChat code scanning, thus, the control device compares the verification characters, opens the barrier gate to allow the vehicle to enter if the verification characters are matched, and generates the entry record of the vehicle with the license plate according to the input license plate number. This has the advantage of not affecting the identification of the license plate at the exit, and the authorization of deduction can be carried out as usual in the field, etc.
Taking the exit of the parking lot as an example, after the camera fails, the license plate recognition does not return any result, the vehicle owner sends the WeChat openID to the server by using the WeChat scanning code of the mobile phone, the control device of the parking lot is connected with the server to obtain the openID, and the control device generates a verification character '123456' in real time and displays the verification character on the display device to prompt the vehicle owner to input the verification character; after the car owner inputs '123456', the control device compares the verification characters, if the verification characters are matched, the control device searches the entrance record of the unlicensed car according to the openID to carry out corresponding charging and fee deduction, and opens the gateway to allow the car to drive away.
Similarly, after the camera fails at the exit of the parking lot, the vehicle owner can input the license plate number when using the mobile phone WeChat code scanning for the vehicle with the license plate, so that the control device compares the verification characters, searches the entry record of the vehicle with the license plate number according to the input license plate number to carry out corresponding charging and fee deduction, and opens the barrier gate to allow the vehicle to drive away.
Of course, before the exit allows the vehicle to drive away, whether the current owner inputting the license plate number originally pays the owner can be judged according to the openID of the micro-message of the owner, and if not, corresponding prompt is carried out.
Through the embodiment, the technical scheme of the invention can be used for the entrance and the exit of the parking lot. It should be noted that the application range of the technical solution of the present invention is not limited to the above-mentioned embodiments.
