Road condition monitoring method and system based on vision and radar, and equipment

Abstract

The invention discloses a road condition monitoring method and system based on vision and a radar, and equipment. The method comprises the steps of: obtaining a monitoring video of a road surface in real time, and obtaining the position of a vehicle in an image coordinate system in the monitoring video through a preset model; scanning the road surface through the radar to obtain the position of the vehicle on the road surface in a polar coordinate system; converting the position of the vehicle in the polar coordinate system into a position in an image coordinate system, and obtaining the corresponding relation of the vehicle between the monitoring video and the radar ; fusing the first attribute and the second attribute of the vehicle according to the corresponding relation to obtain vehicle condition information of the vehicle; and judging road condition information according to the condition information of the vehicle, and conducting early warning according to the road condition information. According to the method provided by the invention, feature information of each vehicle is integrated through calibration and fusion of the monitoring video and the radar, and effective road information can be provided for supervision departments and travelers; and the road condition information of the vehicles on the road can be obtained, and intelligent information fusion and traffic scheduling can be completed according to the road condition information.

Description

technical field [0001] The invention relates to the technical field of road condition monitoring, in particular to a road condition monitoring method, system, device and storage medium based on vision and radar. Background technique [0002] The road is an important part of the city. With the development of society and the increasing demand of the supervision department for real-time collection of road traffic data, the construction of new road intelligent monitoring is an important direction of the current intelligent trend. At present, road monitoring equipment mainly includes surveillance cameras and road structured cameras. [0003] At present, the equipment used for road traffic monitoring has the problems of insufficient information collection coverage and difficult data integration; lack of intelligent monitoring and intelligent scheduling capabilities; insufficient real-time intelligent identification of roads; real-time integration of road information, road danger, ...
