ETC portal license plate accurate identification method, system and device

Abstract

The invention discloses an ETC portal license plate accurate identification method, which comprises the steps of denoising through an NL-Means algorithm, extracting a single character through a vertical projection method, and identifying a license plate number through an artificial neural network algorithm; carrying out high-definition shooting through a COMS camera, and arranging a light supplementing LED lamp; arranging a communication module to achieve information transmission, arranging a weighing module to weigh a vehicle for automatic payment, and arranging a detection module to detect the operation condition of a device. The invention also discloses an accurate identification system, which comprises a control module. The control module is electrically connected with a display module, the communication module, a storage module, the weighing module, the detection module, a voltage regulation module, an amplification digital-to-analog module and the camera module. The invention further discloses a device for accurately identifying the license plate, the device comprises door frame supporting legs, a door frame top fence is welded to the door frame supporting legs, a control box, a display LED screen and a COMS camera are installed on the door frame top fence, and a light supplementing LED lamp is arranged on the COMS camera.

Description

Technical field [0001] The present invention belongs to the technical field of product ETC, and more specifically, relates to a precise recognition method, precise recognition system and precise recognition equipment of ETC mast license plates. Background technique [0002] In the past, when vehicles were driving in places with toll stations, manual tolls were used. However, once there is a holiday or when the traffic volume is large, it takes a long time to line up to leave the toll station. This will not only affect the drivers or passengers. Time caused a lot of consumption, and also caused a huge workload for toll personnel. Later, with the development of intelligence, almost all toll stations have ETC for self-service payment, saving a lot of time. [0003] ETC is a non-stop electronic toll collection system. ETC dedicated lanes are used for vehicles equipped with ETC in-vehicle devices, using electronic toll collection methods. The ETC electronic non-stop toll collection sys...

Problems solved by technology

[0004] However, the existing ETC electronic toll collection often occurs because the pictures taken are not clear, so that the vehicle cannot pay the toll automatically, which will cause certain payment troubles, and the existing ETC gantry is directly deducting the fee, so that the driver cannot Clearly see the payment information, and the equipment is not user-friendly, and cannot convey certain warm reminders to the driver; and the existing equipment cannot realize remote control transmission when in use, and it is necessary to regularly extract and record the automatic payment equipment, and on-the-spot Some technologies are very simple when extracting the license plate, resulting in the failure of the license plate extraction, or errors in image extraction of the license plate, which will cause certain troubles for automatic payment
