Embodiment approach

[0035] 1) Install portals and high-definition cameras on the section between expressway toll stations to capture real-time pictures of vehicles passing through the portals. Use the ETC device to identify vehicle information, realize two-way microwave communication with toll vehicles, determine the road section the vehicle has passed, and transmit the photos taken to the information storage server of the expressway management office.

[0036] 2) Unified management of the captured vehicle picture information, using the YOLO target detection algorithm to extract vehicle features from the pictures taken by the gantry, train the vehicle target detection model, determine the weight of the network coefficients, and extract the vehicles in the pictures taken by the gantry, Eliminate the influence of the image background.

[0037] 3) According to the vehicle information JSON file captured at the entrance and exit of the toll station, the license plate is analyzed to confirm the entranc...

Abstract

The invention discloses a highway vehicle charging auditing system based on the technology of searching images by images and a driving path dual-collection inspection method. The highway vehicle charging auditing system comprises a vehicle image collection device, an image data transmission unit and an image data processing unit, the vehicle image collection device comprises a door rack and a high-definition camera, and the high-definition camera captures vehicle images passing through the door rack; The image data transmission unit is of a wired or wireless data transmission structure and is used for transmitting the image data to the image data processing unit, shooting vehicle images to train a vehicle detection model, and extracting vehicle features; determining a vehicle driving path according to the time of the vehicles passing through the portal in sequence; obtaining access information according to picture information shot at the entrance and the exit of the toll station; adopting the pedestrian re-recognition technology for finding out information of all the portals passed by the vehicle; and comparing the path of searching the image by the image with the charge flow information, if the path does not accord with the charge flow information, determining that suspected violation exists, and achieving the purpose of convenient auditing according to the real path restored by searching the image by the image.

Description

technical field [0001] The invention belongs to the technical field of road vehicle driving path identification, and relates to a system and a method for combined application of image search technology and vehicle driving path. Background technique [0002] In the current operation process of expressways in our country, the tolls of passing vehicles are collected through the combination of ETC and manual methods. Expressway tolling is an important means for highway operating units to recover road construction costs. Although the expressway toll system has been continuously improved, the phenomenon of evading tolls is still repeated, which has brought huge economic losses to expressway operating units and the country. At the same time, it affects the safe operation of the expressway. How to improve the charging efficiency of the road toll system and accurately check the vehicles that evade tolls has become an urgent problem to be solved. [0003] The current toll collection...
