The embodiment of the application discloses a weighbridge unattended weighing method using a face recognition operation terminal. Referring to fig. 1, the method includes the following steps:
s100: and obtaining order information of the current vehicle to judge the current weighing times of the vehicle.
In the present embodiment, the order information refers to information related to all loaded cargos of the vehicle, such as preset loading weight, delivery destination, personal information of a driver, weighing times and the like of the current cargo; the number of weighing times refers to a first weighing and a second weighing of the vehicle, the first weighing being a weighing after the vehicle is loaded with the goods when the vehicle is not loaded with any goods.
Specifically, vehicle information at a place where the vehicle is located at the weighbridge is identified in a license plate identification mode, after the license plate is identified, order information corresponding to the license plate is obtained from an order system in which the order information is stored, whether the vehicle is weighed for the first time or the second time is checked from the order information (corresponding records can be recorded in the order system during each weighing), and subsequent operation is started according to the weighing times.
S200: verifying whether the personnel information of the vehicle driver seat is consistent before and after weighing based on the weighing times; the personnel information comprises face information.
In this embodiment, the person information indicates whether the driver on the driver seat is the same person when weighing twice before and after.
Specifically, after the number of times of weighing of the vehicle is known, a face image on a driver seat of the vehicle is acquired in a photographing mode, whether the face images of the front and rear times are consistent or not is verified in an image recognition mode, if the front and rear face images are consistent, the next step is started, and if the front and rear face images are inconsistent, the subsequent operation is temporarily interrupted. For example: and acquiring the first weighing of the vehicle at the moment according to the order information, shooting and storing the face image of the driver on the driver seat, when the vehicle is lifted to the ground scale again and the second weighing of the vehicle is acquired, shooting the face image of the driver again, comparing the face image shot for the second time with the image stored in the system, and if the face image is successfully verified with the image in the system, proving that the front driver and the rear driver of the vehicle are the same person, and triggering the next operation.
Further, in one embodiment, the printed voucher information is generated if the personal information of the driver's seat of the vehicle is consistent.
In this embodiment, the voucher information is the factory voucher after being weighed.
Specifically, after the verification is completed, if the information of the first verification is consistent with that of the second verification, the verification is passed, the voucher printing information is triggered, and the vehicle leaves the factory according to the voucher.
Further, in one embodiment, information of persons near the vehicle is acquired; and determining to start face recognition operation according to the personnel information.
In the present embodiment, the face recognition operation refers to a face recognition operation performed on a person in the driver's seat of the vehicle.
