Problems solved by technology

[0004] However, the existing lane information is mainly obtained through map information. When the map information is not updated in time or the map information cannot identify the lane, the lane cannot be accurately divided.

Abstract

The embodiment of the application discloses a lane calibration method and device and electronic equipment. The method comprises the steps: collecting the movement track of each target vehicle in a preset duration through a radar, and forming a track data set; classifying track data in the track data set according to the moving speed to obtain a first track data set and a second track data set; respectively mapping a coordinate information set in the first track data set and a coordinate information set in the second track data set into grid units in a radar coordinate system to form a first track density map including a plurality of reference ridge lines and a second track density map; generating a coordinate vector of a center line of a corresponding lane according to the reference ridgeline; determining the position of a parking line according to the position meeting a second preset condition in the second track density map; and calibrating the lane according to the position of thestop line and the coordinate vector. Therefore, the accuracy of lane division is improved.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a lane marking method, device and electronic equipment. Background technique [0002] In the current intelligent transportation system, it is necessary to provide the data center with vehicle state simulation, traffic statistics and traffic event information within the scope of monitoring roads, all of which must be based on accurate lane information. [0003] The simulation results of monitoring the vehicle state within the road range need to guide the observation of the road boundary; the information collection sections in the traffic statistics data are all related to the lane, such as the traffic flow statistics of the lanes, the average speed statistics of the lanes, and the time headway of the lanes Statistics; a series of traffic event information such as illegal parking detection, retrograde detection, lane change detection, speeding detection...
