Problems solved by technology

In the real environment, the lane lines are parallel, but due to the imaging of the camera lens, the imaged lane lines are no longer parallel
In addition, there are many vehicles at traffic intersections, and the lane lines are severely worn and polluted. It is not easy to identify the lanes and divide the detection area.
Moreover, if the image is collected by lig...

Abstract

The invention discloses a microwave-based vehicle queue length detection method and system, including an array antenna module and a radio frequency module for transmitting multiple beams in the detection coverage area, and receiving the returned multiple beams; a model database is used for detecting the coverage area The coordinate system is established in the area, and each lane is numbered to determine the coordinate range of each lane on the Y axis; the tracking algorithm module is used to analyze multiple beams returned in one scanning cycle; it is also used to determine the vehicle's next The estimated area that will appear in the scanning cycle; it is also used to analyze multiple beams returned in the next scanning cycle; the data processing module is used to synthesize the data of the model database and the tracking algorithm module, and judge whether the speed of the vehicle is less than the predetermined value, to calculate the queue length. The invention can track the state of the vehicle in real time, analyze the queuing situation of the vehicle in real time, avoid being affected by the environment, and provide a basis for the control of traffic signals.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a microwave-based vehicle queue length detection method and system. Background technique [0002] Transportation is the lifeblood of a city and the most important infrastructure in the city's economy and people's lives. Traffic control is a social public welfare undertaking related to the national economy and the people's livelihood. It is closely related to the production and life of the public. The stable and sustainable development of cities and the improvement of people's living standards play an important role. Over the past 30 years of reform and opening up, with the rapid economic and social development of our country and the gradual expansion of urban population, the number of motor vehicles has shown a trend of rapid growth. The existing road network has been unable to meet the growing traffic demand, resulting in urban traffic accidents A series of problems such as freq...
