A secondary license plate recognition system and method for non-stop mobile payment lanes on expressways

Abstract

The invention relates to a secondary license plate recognition system and method for a non-stop mobile payment lane of an expressway. By installing front and rear license plate recognition devices at the front end and rear end of the lane entrance respectively, the problem of vehicle passing speed is solved; by installing The two cameras of the front or rear license plate recognition equipment on both sides of the lane can solve the impact of reflection; through the asynchronous flash capture of the two cameras, the problem of light and darkness can be solved; through the front and rear license plate recognition equipment, the success rate of capture can be solved problem; through mobile phone prediction data, secondary license plate recognition algorithm and data analysis, the problems of license plate accuracy and license plate decking can be solved; the invention can fully meet the technical requirements of the expressway non-stop mobile payment system, and at the same time effectively prevent decked vehicles from entering and leaving the highway. , to avoid misjudging the vehicle and avoiding the wrong deduction of tolls. Utilizing the present invention, not only the non-stop mobile payment in the MTC and ETC lanes can be accurately realized, but also the rapid passage of vehicles in the MTC and ETC lanes without stopping can be realized.

Description

technical field [0001] The invention relates to the field of expressway non-stop mobile payment, in particular to a secondary license plate recognition system and method for expressway non-stop mobile payment lanes. Background technique [0002] Domestic expressway toll collection takes the MTC (parking) manual toll system and the ETC (non-stop) automatic toll collection system as the main toll collection modes, and a professional and relatively complete expressway toll collection system has been established. At present, mobile parking payment for expressway tolls has gradually become a hotspot for expressway toll payment. Alipay, WeChat scanning or being scanned payment is accepted by many road owners, but parking card collection, return card, mobile phone scanning payment, solves how to pay , failed to improve the lane traffic efficiency of high-speed toll stations. [0003] Expressway toll fee non-stop mobile payment came into being. The core of its system is to use the ...

AI Technical Summary

Problems solved by technology

The expressway toll industry is a relatively professional industry. There are performance indicators for the speed of vehicles passing through the toll booth, the passing rate, the correct rate of vehicle recognition, and the handling of normal or abnormal lanes, especially the obtained vehicle license plate. Accuracy and authenticity will directly affect the performance indicators of the mobile payment system for expressway tolls without parking. If the license plate is incorrectly recognized, the fees of other vehicles will be deducted by mistake, and the incorrect license plate recognition will also lead to misjudgment of identity and the inability to enter the toll booth without stopping. , or mistakenly put the vehicle into the toll booth, especially if the system cannot identify the licensed vehicle, criminals will take risks, the licensed vehicle enters and exits the highway, and the licensed vehicle pays the toll for no reason. Therefore, the capture accuracy of a simple single camera, Obviously, it cannot meet the requirements of the high-speed toll system for functions and performance indicators
