Abstract

The invention discloses a method and device for recognizing a vehicle type in an ETC lane. The method and the device are applied to an ETC system, and the ETC system is connected with a video obtaining device. The method comprises the steps of first obtaining an ETC lane picture transmitted by the video obtaining device, and obtaining a vehicle picture of a to-be-recognized vehicle form the lane picture according to the position of the to-be-recognized vehicle in the ETC lane; performing vehicle type recognition, and obtaining corresponding vehicle type recognition information; obtaining vehicle type information corresponding to an OBU, performing vehicle type matching according to the vehicle type information and the vehicle type recognition information, and obtaining corresponding matching results; and finally executing corresponding operation according to the matching results. By means of the method, the conditions that the vehicle type information corresponding to the OBU does not correspond to a vehicle can be avoided, vehicle type recognition accuracy is improved, and the problem of toll evasion of the vehicle can be solved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and device for identifying vehicle types in an ETC lane. Background technique [0002] Intelligent transportation, which can provide various services for traffic participants, is the development direction of the future transportation system. Under this trend, the ETC (Electronic Toll Collection, electronic toll collection) system is widely used. [0003] The ETC system includes a background system, a lane controller, and an RSU (Road Side Unit, Road Side Unit), and is arranged beside the ETC lane. When the vehicle passes through the toll booth, the ETC system interacts with the OBU (On board Unit) installed on the vehicle to realize the identification of vehicle information, determine the model of the vehicle, and deduct the model from the account of the vehicle Corresponding fees, so that there is no need for manual payment, and there is no need for parking, r...
