Problems solved by technology

But this type of method has the following problems: (1) in terms of security, because the electronic license plate has its own access security risk, the security risk on the communication link, and the security risk inside the reader, the identification security of the electronic license plate is limited; (2) Because it communicates by radio frequency, it has short effective recognition distance, stability, poor anti-interference, and is greatly affected by the weather. Especially when there are many vehicles on the road, it is easy to be interfered by other vehicles (such as occlusion, electromagnetic interference, etc.) etc.) lead to difficult identification and easy missed judgment; (3) Passive electronic license plate readers need to be equipped with tall and cumbersome antennas, and vehicles with false identities have already escaped when they see them; Economic burden and trouble, and in more cases, misjudgment is caused by the lack of power of the electronic license plate, and there will be problems in a large number of applications; (4) The direction angle of wireless recognition is limited, such as the electronic license plate is installed on the front windshield of the car It can only be aligned to the front of the car for identification, and it can only be aligned to the rear of the car

Embodiment Construction

[0018] The present invention is implemented according to the following scheme: a method for automatic inspection of road vehicle identity, comprising the following steps:

[0019] ①. Obtain the characteristic image of the physical appearance of the vehicle through the imaging device installed on the inspection equipment, and convert the obtained characteristic image of the physical appearance through image processing software to extract the characteristic information of the vehicle appearance;

[0020] ②. Obtain the geographic location information and time information of the location where the vehicle is located when the inspection equipment is imaged by the positioning device. The camera can be upgraded and modified. On the basis of making full use of existing resources, we can quickly set up enough inspection points on all roads and traffic arteries, and set up a network of inspections of illegal vehicles. If it is a mobile inspection device, the geographic location informat...

Abstract

The invention relates to an auto-auditing method for road vehicle identity, which takes pictures of exterior feature information of the vehicle through an imaging device; acquires the information of image formation time and geographic position of a piece of audit equipment through a positioning equipment, transmits the acquired information data to a management server, acquires the geographic position information and the corresponding time information of the vehicle through an on-board positioning equipment and transmits the information to the management server; compares the exterior feature information of the vehicle with the vehicle identity information registered in the management server and compares the time and geographic position information of image formation acquired with the geographic position information at corresponding time of the on-board positioning equipment, the vehicle identity condition can be judged to be abnormal if the results of the two comparisons are not the same and not the sole. The auto-auditing method resolves the difficulty of false license vehicles and false registered vehicles when using separately stored license plate numbers which may be copied or tampered with; the auto-auditing method also reduces cost, improves reliability and practicality and reduces operation and maintenance cost; the auto-auditing method is not restricted to distance and enhances recognition rate and reliability.

Description

technical field [0001] The invention relates to an automatic inspection method for road vehicle identities. Background technique [0002] Existing road vehicle identity inspection methods can be summarized into the following categories: [0003] 1. Human eye recognition: law enforcement officers stop the driving vehicle on the side of the road to check the license plate, physical characteristics of the vehicle and documents. Its disadvantages are low efficiency, narrow inspection area, and difficulty in identifying false identity vehicles with a high degree of fraud, which is far from meeting the needs of modern intelligent transportation. [0004] 2. Electronic license plate: Each vehicle is equipped with a dedicated electronic license plate, which stores the electronic identity information of the vehicle, and uses radio frequency to exchange information with reading equipment to achieve the purpose of identifying the vehicle. This type of method is convenient for automat...
