RSU antenna and video image joint detection result matching method

Abstract

The invention discloses an RSU antenna and video image joint detection result matching method, which comprises the steps of reading vehicle information of a vehicle-mounted OBU unit through an RSU antenna, forming first result data by the read vehicle information and a vehicle snapshot image, and queuing to enter an OBU vehicle information queue; recognizing the vehicle information through a videoimage analysis and recognition module, forming second result data by the recognized vehicle information and the vehicle snapshot image, and queuing up to enter a video recognition vehicle informationqueue; and in the synchronization time, extracting the first result data of the OBU vehicle information queue and the second result data of the video identification vehicle information queue one by one, matching the first result data and the second result data by using the license plate number, and if matching succeeds, outputting the successfully matched first result data and second result data.According to the invention, the combination of RSU antenna detection and video image analysis technologies is realized, the detection results supplement each other, the vehicle capture rate is greatly improved, and the vehicle multi-detection rate is more effectively reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a method for matching results of joint detection of RSU antennas and video images. Background technique [0002] At present, the ETC electronic toll collection system uses the RSU antenna (roadside unit) to detect the vehicle-mounted OBU unit, and after receiving a response to establish a communication connection, read the vehicle information on the vehicle-mounted OBU unit. If the RSU antenna and the vehicle-mounted OBU unit are damaged or blocked, the communication connection cannot be established, and the information of the high-speed section of the vehicle passing through cannot be recognized, and the basis for payment cannot be generated, resulting in problems such as missed payment and incorrect billing. [0003] The joint detection of RSU antenna and video image analysis applied to vehicles passing through the ETC lane of expressway is an important means to impro...
