Embodiment 1

[0074] This embodiment provides a vehicle information matching method, such as figure 1 shown, including the following steps:

[0075] S1. Obtain the vehicle information of one or more vehicles within a certain time range. The vehicle information includes the first information contained in the vehicle's electronic license plate and the second information contained in the physical license plate. The first information and the second information include the corresponding vehicle. License plate number and vehicle appearance information (such as vehicle color, model, brand, etc.). The above license plate number and vehicle appearance information can be stored in the radio frequency electronic chip in the electronic license plate, which can be read by the electronic license plate reader, and the first information can be obtained based on this; For the license plate image, the above license plate number and vehicle appearance information can also be obtained, and the second informat...

Embodiment 2

[0104] This embodiment provides a vehicle information matching system, such as Figure 4 As shown, it includes: vehicle information acquisition unit 1 , precise matching unit 2 , precise matching judging unit 3 , fuzzy matching unit 4 , and verification unit 5 .

[0105] Wherein the vehicle information obtaining unit 1 is used to obtain the vehicle information of one or more vehicles within a certain time range, the vehicle information includes the first information contained in the electronic license plate of the vehicle and the second information contained in the physical license plate, the first information and the second information contained in the physical license plate. The second information includes the license plate number of the corresponding vehicle and the appearance information of the vehicle. Preferably, the vehicle information acquisition unit 1 includes:

[0106] The valid information judging unit 11 is used to judge whether the read electronic license plate ...

Embodiment 3

[0129] This embodiment provides a monitoring device, including: a physical license plate recognition unit 6 , an electronic license plate information reading unit 7 and a processing unit 8 . in:

[0130] The physical license plate recognition unit 6 is used to collect the image information of the physical license plate of the vehicle. In a specific application, the physical license plate recognition unit 6 can use a high-definition camera, which can collect clear image information of the physical license plate and appearance of the vehicle.

[0131] The electronic license plate information reading unit 7 is used to read the electronic license plate information of the vehicle. In a specific application, the electronic license plate information reading unit 7 can use an electronic license plate information reader, which can quickly and accurately read the electronic license plate information transmitted by the electronic license plate of the vehicle.

[0132] The processing un...

Abstract

The invention provides a vehicle information matching method and system, and a monitoring device. The method comprises the steps: obtaining first information of electronic license plates of one or more vehicles and second information of physical license plates in a certain time period; judging whether there is second information accordance with certain first information or not; determining that the vehicle information matching of a vehicle corresponding to the first information is successful if there is the second information accordance with certain first information, or else, carrying out fuzzy matching of the first information with the unsuccessfully matched second information in the vehicle information. In other words, the method and system still can correct the second information in a fuzzy matching mode under the conditions that an external environment is severe (strong light, misty rain, or poor light), or a physical license plate cannot be recognized because the physical license plate is polluted or shaded (inaccurate second information of the physical license plate) and there is wrong recognition, and improve the accuracy of vehicle information recognition.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle information matching method, system and monitoring device. Background technique [0002] Physical license plate recognition based on video image technology is greatly affected by factors such as the environment, lighting, and weather, and some people will deliberately block, deface the license plate, and change the license plate number in order to avoid investigation, resulting in the inability to perform physical license plate information. Accurate and effective identification. Therefore, the vehicle identification effect based solely on video image technology is difficult to meet the requirements of smart city traffic management, public travel services, and comprehensive management of social security. [0003] The electronic license plate based on radio frequency technology is less affected by the external environment and has high recognition accur...
