Abstract
The invention relates to a vehicle identification and charging device for unlicensed vehicles and vehicles entering and exiting parking places when identification results are not matched. The device mainly comprises ETC electronic toll collection device, license plate recognition device, degree of depth learning machine, the device of seeking help of long-range passage, and the car accuse machine, in a flexible way to the ECT car, there is the car of tablet and no car of tablet, and because various factors such as identification error, discrepancy vehicle physical structure or license plate change lead to the inconsistent vehicle of the vehicle information identification of entering and leaving to carry out comprehensive discernment and parking charge, make the vehicle efficiency of entering and leaving to show and promote, the intellectuality in parking area has really been realized, unmanned management.
Description
Technical Field
The utility model relates to a vehicle identification and charging device that can vehicle information discernment especially involves identification and charging device that unlicensed vehicle and discrepancy field formula identifying information match inconsistent vehicle belongs to vehicle identification device field.
Background
The existing unattended charging device needs to be parked and read the card when a vehicle enters a field, and the parking card is recovered when the vehicle leaves the field, even the complicated step of manual cash payment and change giving can not be avoided. The efficiency of the vehicles entering and leaving the field is not improved obviously. The original purpose of the unattended parking lot is to realize unmanned charging through a self-service payment machine, so that the intellectualization and the unmanned charging of the parking lot are really realized, the main purpose of the unattended parking lot is to seek the convenience and the maximization of the turnover rate of a car owner, and the traditional unattended parking lot is unsatisfactory in the aspects of improving the parking experience of the car owner and the benefit of the parking lot.
The license plate recognition technology is an automatic license plate recognition technology based on image processing and Optical Character Recognition (OCR), and mainly adopts the idea of 'different license plates of different vehicles' to recognize the vehicles. When a vehicle enters a parking lot, the device automatically records data such as a vehicle photo, a license plate number, entrance time and the like by using a license plate recognition camera; when the vehicle leaves the parking lot, the device utilizes the license plate recognition camera to automatically record data such as a vehicle photo, a license plate number, leaving time and the like, and matches the data with the entering data to calculate the payment condition of the parking fee, particularly, an electronic payment tool is also applied to the parking lot, and the vehicle which finishes payment can leave the parking lot without barriers.
However, when the camera identifies the license plate, due to the influence of objective factors such as illumination, the neatness degree of the license plate, rainy and snowy weather, vehicle queuing and the like, a certain error is generated in an identification result, the highest value in the daytime is about 99.5%, and the highest value in the nighttime is about 98%. The fake-licensed vehicles are partially recognized as the fake-licensed vehicles, once the fake-licensed vehicles are recognized at the entrance or the exit, the exits cannot be matched with the correct vehicles, and for the unattended parking lot, the entrance recognition errors and the entrance of the fake-licensed vehicles are pain spots. And the payment work of the vehicle which is not paid is still compensated by the staff of the sentry box after the identification is invalid, so that the unattended operation cannot be completely realized, and particularly, the identification and charging operation cannot be finished by using a camera to identify the license plate in the face of a real unlicensed vehicle.
The existing technology for solving the problem of the identification and charging of the unlicensed vehicles can only solve the entrance condition of the unlicensed vehicles, is complex to operate, and still needs human intervention when the vehicles with the wrong license plate identification enter an exit. For example, the traffic of a crown block reaches 1000 cars in a parking lot, the identification accuracy of the ETC + camera reaches 99.5%, 5 cars are identified incorrectly (no unlicensed car is involved), and the 5 cars need human intervention processing, so the identification of the ETC camera still cannot achieve the real unattended purpose, namely the current so-called unattended parking lot in the market is very dependent on the identification accuracy of a license plate, and the single identification mode cannot really achieve the ideal unattended function.
Disclosure of Invention
The utility model discloses a solve the charge problem of unlicensed vehicle and access vehicle identification information matching inconsistent vehicle, designed an identification and charging device of unmanned on duty parking area vehicle, utilize this identification and charging device can really realize the discernment of all kinds of vehicles and accomplish the charge, realize the parking area unmanned. The vehicle identification and charging device for the unattended parking lot mainly comprises the following sub-devices and a vehicle control machine:
the camera shooting sub-device comprises a camera and is used for identifying the license plate;
the ETC toll collector comprises a card reader and is used for exporting ETC to pay by card reading;
the deep learning machine is used for acquiring the characteristic information of the vehicle image;
the remote passage help-seeking sub-device is used for remotely seeking help for a driver and remotely opening a brake when an intranet fails;
preferably, the vehicle further comprises a ground induction coil for inducing the vehicle.
Preferably, the ETC toll collector device may include an RSU device for identifying an OBU on a vehicle and performing a toll collection operation.
Preferably, the remote passage help-seeking sub-device adopts a 4G/5G mode for communication and is used for remote help seeking of a driver and remote brake opening when an intranet fails.
When an unmanned vehicle enters and exits the identification and charging device of the parking lot at the entrance and exit of the parking place, once the vehicle enters the parking place, the depth characteristics of the vehicle are extracted by adopting a depth learning algorithm through a depth learning machine, the depth characteristics comprise the environment-friendly label position of the vehicle, the position of the interior decoration, the color of the vehicle, the skylight, the type of the vehicle and the like, and the unique characteristics of the vehicle can be distinguished, so that the vehicle owner does not need to park at the entrance to take a card or a ticket, or alternatively, a code is scanned. The depth characteristics of the vehicles are also collected when the vehicles are out of the field, the vehicles with ETC carry out ETC fee deduction, the vehicles without ETC adopt license plate numbers to calculate fee, the rest vehicles without license plates or vehicles with inconsistent license plate numbers in and out of the field are matched, then the depth characteristic matching is adopted, the characteristics of the vehicles out of the field are respectively matched with the characteristics of the vehicles in the field, the most similar vehicles are found and threshold values are met, and then the matching is correct.
The invention has at least the following beneficial effects:
the recognition accuracy is improved to 20000 vehicles once by present 200 vehicles need manual intervention once and then needs manual intervention once, realizes real unmanned on duty parking area. The vehicle identification system can identify the unlicensed vehicles and the vehicles with unmatched access identification information, can charge and provide service for vehicles through remote help, and gives consideration to identification and payment operation of most social vehicle types.
