License plate information acquisition and restoration method and system

Abstract

The invention relates to a license plate information acquisition and restoration method and system, and belongs to the technical field of computers. The license plate information collecting and repairing method and system are adopted. The method is based on the recognition of a vehicle image and a license plate image in a vehicle picture. The method comprises the steps: obtaining initial license plate information, analyzing and repairing the initial license plate information based on a numbering rule; automatically generating the rule to optimize the license plate information, so that automatic, convenient and high-accuracy license plate information acquisition and restoration are realized, manual operation is not needed in the whole process, the automation degree is high, the license plate recognition accuracy of the vehicle picture shot by the road monitoring equipment can be greatly improved, and convenience is provided for subsequent data summarization and big data application.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to the field of image recognition technology, in particular to a method and system for collecting and repairing license plate information. Background technique [0002] As of December 28, 2018, the total mileage of China's expressways has reached 140,000 kilometers, ranking first in the world. On the 140,000-kilometer main artery, there are more than 10,000 charging stations. The toll station continuously collects manual or ETC toll data to the provincial expressway system through data collection equipment. The provincial expressway system can synchronize the high-speed data toll details to the expressway database of the Ministry of Communications in real time through the public network or private network. During the entire process of data generation, the toll collector distinguishes the type of vehicle that pays the fee and the type of vehicle that is exempt from paying the toll...

Problems solved by technology

In addition, the systems and recognition equipment accuracy of each toll station are inconsistent, and the data will inevitably have various situations such as license plate number, axle number recognition errors, transmission errors, and manual errors.

[0003] The main problem lies in the inaccurate recognition of the license plate information of the vehicle image, which leads to the inability of one-to-one correspondence between the image and the toll traffic data. There are many data in the system that need to be further checked and repaired, which reduces the accuracy and reliability of the overall system.
