Problems solved by technology

However, with the method of camera monitoring, although real-time and accurate monitoring can be carried out manually, the amount of labor required is extremely large; although video processing technology can also be used for analysis and judgment, there are great difficulties in identifying and monitoring moving vehicles
Moreover, the camera's monitoring of the road surface is greatly affected by light and weather

Abstract

The invention provides multi-lane vehicle flow counting method, device and equipment and a storage medium. The method herein comprises: acquiring first radial distances from radar to monitoring pointson lanes, wherein the radar is frequency modulated continuous wave millimeter radar; receiving reflected signals acquired by the radar from the lanes, subjecting the reflected signals and a local oscillator signal to frequency mixing to obtain medium-frequency signals, subjecting the medium-frequency signals to one-dimensional spectral analysis to obtain a first distance spectrum, acquiring a driving velocity and radar monitored distance of a target vehicle according to a preset distance amplitude threshold, the first distance spectrum, the first radial distances and a preset velocity amplitude threshold, and counting vehicle flows of the lanes within predetermined time according to the driving velocity and radar monitored distance of the target vehicle. The method, device and equipment and the storage medium can count vehicle flows of multiple lanes, response speed is high, and flow counting is accurate.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a multi-lane traffic flow statistics method, device, equipment and storage medium. Background technique [0002] With the development of the times, people's living standards continue to improve, urban modernization is changing with each passing day, private vehicles have increased rapidly, and road passenger and cargo transportation has developed rapidly, resulting in a greater traffic load. With the country's strategic deployment of big data and Internet +, smart transportation has become a necessary way for traffic management departments to supervise traffic. Smart transportation is a harmonious and unified management of pedestrians, vehicles and roads through information technology, so as to realize a real-time, accurate and efficient transportation management system. Among them, the monitoring and research of road traffic flow is an indispensable part. How...
