Problems solved by technology

[0003] In practical applications, when there are multiple vehicle-mounted OBUs within the coverage of a certain RSU, the RSU may not be able to distinguish these vehicle-mounted OBUs, resulting in car-following interference, wrong vehicle positioning, wrong payment, etc., and in the existing ETC system, RSUs and OBUs located in adjacent lanes may also generate adjacent lane interference, which can cause transaction confusion

Abstract

The invention discloses an ETC system integrated with the infrared camera function, and a vehicle identification and location method. The ETC system comprises a vehicle-mounted OBU and a road-side unit. The vehicle-mounted OBU and the road-side unit are in communication through wireless signals, so that the data transfer and the payment are realized. An infrared camera is installed above the lane of the ETC and is used for capturing an infrared image of an interested region and transmitting the corresponding information to the road-side unit. The infrared image is used for acquiring the engine position of a vehicle and the profile of the vehicle. An infrared reference point is located within the interested region and is adopted as a reference during the acquiring process of the engine position and the profile of the vehicle. Based on the ETC system, by utilizing the infrared image, the type information of the vehicle can be obtained and the vehicle-mounted OBU is facilitated to be positioned. Therefore, the transaction success rate and the reliability of the ETC system are improved.

Description

technical field [0001] The present invention relates to the field of ETC (namely ElectronicTollCollection), in particular to an ETC system integrating infrared camera identification function and a vehicle identification and positioning method used in the ETC system. Background technique [0002] The ETC system is an automatic electronic toll collection system that is mainly researched and promoted in the world at present, and it is suitable for vehicle toll collection solutions in highways and bridges and tunnels with heavy traffic. The standard accessories of the ETC system include on-board OBU (On-BoardUnit, also known as on-board electronic label or on-board electronic unit) and roadside unit (RoadSideUnit). The vehicle-mounted OBU is installed on the vehicle. When the vehicle passes the toll station on the ETC lane, the vehicle-mounted OBU communicates with the roadside unit (RSU, RoadSideUnit) through radio frequency wireless signals, and the toll payment can be complet...
