Microwave-based intersection presence detection method and system

Abstract

The invention provides a crossing existence detection method and system based on microwaves. The crossing existence detection method comprises a traffic parameter arrangement step, a road traffic background learning step, a road background noise inhibition step, a calculation step, a coordinate system establishing step, a model classifying step, a tracking processing step and an information output step. The method provided by the invention has the following advantages: compared to such problems of not high environment adaptability, quite poor reliability, too high later maintenance cost and the like of conventional detection equipment in the prior art, the existence detection method based on a microwave (millimeter wave) mode, brought forward by the invention for the purpose of eliminating the defects of the conventional detection equipment can run around the clock, is high in precision, high in reliability, high in economic benefit-cost ratio and simple in installation and can rapidly and accurately detect crossing existence information.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a microwave-based intersection detection method and system. Background technique [0002] With the gradual acceleration of the urbanization process, the problem of urban road traffic has become a common problem faced by major cities in China. As the junction of urban roads, intersections play a very important role in road network and traffic flow. How to make full use of the existing road resources, improve the passing capacity of the intersection and reduce the delay time through the intelligent signal control system has always been an important research topic in the field of traffic engineering. The practical experience of developed cities in foreign countries shows that traffic problems cannot be solved simply by building roads and expanding traffic capacity, and the increase in road capacity will never keep up with the increase in traffic demand. Under th...

[0008] This method has disadvantages: the on-site installation and construction are very cumbersome, the road needs to be closed during installation, and the road surface is seriously damaged. Single, the detection area is a section detection, the detection area is very narrow, and the economic benefit cost ratio is very low

[0010] This method has disadvantages: the on-site installation and construction are cumbersome, and the road needs to be closed during installation, which will cause damage to the road surface. Because the internal power supply is powered by a rechargeable battery, the service life is short, the detection parameters are single, and the detection area is a cross-sectional detection, which is very difficult. Small and small, very low cost-benefit ratio

Video detection technology has very high requirements for real-time image recognition, and the accuracy of vehicle detection and video in complex backgrounds is very low, for example, video detection at night and in relatively dark, severe haze, heavy rain, heavy snow and other bad weather Technology cannot detect, so this device cannot be tested 24 / 7
