Vehicle driving speed and license plate recognition system and method based on invisible light imaging

Abstract

The invention discloses a vehicle driving speed and license plate recognition system and method based on invisible light imaging. The system comprises infrared imaging equipment mounted above a road or on one side of the road and an image processing computer which is arranged at a monitoring center and is connected and communicated with the infrared imaging equipment through a network, and an infrared reflecting film is attached to a license plate of a vehicle to be identified; The method comprises the following steps: 1, acquiring and transmitting a video; 2, carrying out vehicle driving speed detection; 3, carrying out license plate recognition. The method is low in implementation cost; The system is convenient to install and maintain, high in vehicle driving speed detection precision and high in license plate recognition precision, road traffic can be effectively controlled, traffic accidents are reduced, light pollution and potential safety hazards caused by visible light supplement when visible light is adopted for vehicle speed measurement and license plate recognition are avoided, and good economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of video detection, and in particular relates to a vehicle speed and license plate recognition system and method based on non-visible light imaging. Background technique [0002] In today's society, intelligent transportation system is the development trend of road transportation. The continuous development and continuous improvement of the visual intelligent traffic monitoring system has laid a good foundation for the practical application of the management system of vehicle road transport infrastructure. In recent years, my country's intelligent transportation industry has developed rapidly. As an important component of intelligent transportation, the vehicle identification system is widely used in off-site law enforcement in cities. However, there are still many problems in the current vehicle identification system. The traditional vehicle identification system is based on LED supplementary light. system,...

Problems solved by technology

However, the disadvantages of the traditional identification system are: high cost, inconvenient installation and maintenance, and hidden safety hazards in visible light

For example, the Hangzhou Traffic Police Detachment proposed in 2015 that the current system of frequent lighting supplementary light will cause urban light pollution, and easily cause short-term visual obstacles to drivers and cause traffic hazards; question
