Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as Figure 6 As shown, the method for automatically generating lanes by traffic millimeter-wave radar in this embodiment includes steps:

[0035] 1) The detection range of the radar is divided into blocks along the normal direction of the radar;

[0036] 2) For a period of time, the vehicle position and the number of vehicles passing through each block are counted according to the direction perpendicular to the normal, and the cluster center in the corresponding block is selected;

[0037] 3) Screening the clustering centers in different blocks to obtain the clustering target points of each single lane;

[0038] 4) Fit the clustering target points of the screened single lane to obtain the center line of the lane and generate the corresponding lane.

[0039] The present invention uses the target position information detected by th...

Abstract

The invention discloses a method and system for automatically generating a lane by a traffic millimeter-wave radar, a medium and equipment. The method comprises the following steps of: 1) partitioningthe detection range of the radar along the normal direction of the radar; 2) counting the positions and the number of vehicles passing through each block in a period of time according to a directionperpendicular to a normal, and selecting a clustering center in the corresponding block; 3) screening the clustering centers in different blocks to obtain clustering target points of each single lane;and 4) fitting the screened clustering target points of the single lane to obtain a lane center line, and generating a corresponding lane. The method has the advantages of simple operation, automaticlane generation according to radar information, reduction of radar deployment difficulty, enhancement of radar adaptation environment and the like.

Description

technical field [0001] The present invention mainly relates to the technical field of radar, in particular to a method, system and medium for automatically generating lanes by traffic millimeter-wave radar. Background technique [0002] At present, millimeter-wave radar is widely used in the field of transportation, such as vehicle speed detection, vehicle fixed-point capture, traffic flow statistics, and road condition information detection. For long-distance radar in traffic applications, the host computer is usually used to observe the target. The host computer can set the number of lanes and the width of the lane. Lane, which makes it possible to measure the distance, speed, angle and other information of the target when using radar, and cannot accurately locate the lane where the vehicle is located. Therefore, it is necessary to locate many events in the lane (such as illegal occupation of emergency lanes, rear-end accidents, etc.) ) cannot be performed. Moreover, the...
