Vehicle traffic information monitoring method and system combining RFID and machine vision

Abstract

The invention belongs to the technical field of traffic information monitor and relates to a vehicle traffic information monitor system integrating RFID and machine vision, which comprises a computerized vehicle and traffic management center, a subordinate machine, a CCD camera, a radiofrequency sense transmitter / receiver, an alarm circuit and a wired or wireless communication interface. The subordinate device receives the video frequency information captured by the CCD camera and the radiofrequency information read by the radiofrequency sense transmitter / receiver, compares and analyzes the two sorts of information, transmits information on whether the video information of vehicle passing by the intersection complies wit the radiofrequency information as well as the information about the vehicle number plate, the time and direction for passing by intersection, to a computerized vehicle and traffic management center via a wired or wireless communication interface. Besides, the invention provides a monitor method adopted by the system. Therefore, the invention, while coordinating with RFID and machine vision, is able to easily judge the legality of running vehicle and resolve the problems in the existing vehicle information monitor system.

Description

technical field [0001] The invention relates to a method for monitoring traffic information, in particular to a method for monitoring vehicle traffic information and its realization. Background technique [0002] Traffic is the lifeblood of the national economy. With the acceleration of the modernization process, urban traffic is becoming more and more congested. In major cities in my country, traffic jams have become a common phenomenon in urban traffic, which seriously hinders the development of the national economy, causes urban air pollution and damages the environment. In addition, many problems such as hit-and-run, stolen vehicles, vehicle smuggling, scrapped vehicles on the road, false license plates, and fee evasion have not been well resolved for a long time. [0003] Intelligent Transport System (ITS for short) is the only way for transportation development in the 21st century. The basis of intelligent transportation system is the accurate detection of vehicle in...

Problems solved by technology

The biggest disadvantage of this method is that it cannot detect vehicles that are not equipped with radio frequency (RFID)

The designs that adopt machine vision (video) include: "Multimedia Intelligent Monitoring Method and System" (application (patent) No.: 02113826.5) designed by Ji Dawei, etc., "Traffic Flow Detection Based on Video Vehicle Optical Feature Recognition Matching" designed by Li Yimin, etc. System" (application (patent) number: 02113826.5), "video traffic dynamic information collection equipment" designed by Liu Jianwei (application (patent) number: 02271592.4), etc. Vehicles with license plates and sets of license plates, etc.

[0005] There are also many detection methods for detecting vehicle information, such as ground sensing coil: "Underground Integrated Vehicle Detector" designed by Lin Guisheng (application (patent) number: 200410010280.0); such as microwave: "A Method Using the Doppler Effect" designed by Hu Minghua Micro-fluctuation target monitoring radar" (application (patent) number: 86101543); such as photoelectric switch or pressure, vibration, etc.: "vehicle traffic information detection system" designed by G. O. Giddold (application (patent) number: 95192677.2), "Multifunctional Infrared Reflective Vehicle Detector" designed by Pan Daren et al. (Application (Patent) No.: 92214682.9), "A Laser Vehicle Detector" designed by Wang Qihua et al. (Application (Patent) No.: 200510086553.4), "Steel wire vehicle detector" (application (patent) number: 85203172) designed by Fu Lingxun, etc., "automatic identification and statistics method and device for automobile models" designed by Min Jiang, etc. (application (patent) number: 89108862.8); The advantage is low cost, the disadvantage is that the information is single, and the passing vehicles are easy to interfere with each other
