Vehicle speed and license plate recognition method based on non-visible light imaging

Abstract

The invention discloses a vehicle speed and license plate recognition method based on non-visible light imaging. The vehicle speed and license plate recognition system adopted includes an infrared imaging device installed above the road or on the side of the road and an infrared imaging device installed in the monitoring center and integrated with the infrared The imaging device connects and communicates with an image processing computer through a network, and the license plate of the vehicle to be recognized is pasted with an infrared reflective film; the method includes steps: 1. video collection and transmission; 2. vehicle speed detection; 3. license plate recognition. The invention has low implementation cost, convenient system installation and maintenance, high vehicle speed detection accuracy, high license plate recognition accuracy, can effectively control road traffic, reduce traffic accidents, and avoid visible light supplementary light when using visible light for vehicle speed measurement and license plate recognition It causes light pollution and safety hazards, and has good economic and social benefits.

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 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, and adopts...

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
