Embodiment Construction

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

[0034] like Image 6 As shown, the method for automatically generating a lane by a traffic millimeter-wave radar in this embodiment includes the steps:

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

[0036] 2) Count the vehicle position and number of vehicles passing through each block within a period of time, according to the direction perpendicular to the normal line, and select the cluster center in the corresponding block;

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

[0038] 4) Fit the clustered target points of the single lane after screening, obtain the lane center line, and generate the corresponding lane.

[0039] The present invention utilizes the target position information detected by the radar...

Abstract

The invention discloses a method, system, medium and equipment for automatically generating lanes by a traffic millimeter-wave radar. The method includes the steps of: 1) dividing the detection range of the radar into blocks along the normal direction of the radar; The vehicle position and the number of vehicles in each block are counted according to the direction perpendicular to the normal, and the cluster centers in the corresponding blocks are selected; 3) The cluster centers in different blocks are screened to obtain each single lane 4) Fit the clustering target points of the single lane after screening to obtain the center line of the lane and generate the corresponding lane. The invention has the advantages of simple operation, automatic generation of lanes according to radar information, reduction of difficulty in radar deployment, enhancement of radar adaptation to the environment, and the like.

Description

technical field [0001] The 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 snapshot, traffic flow statistics, and road condition information detection. For long-distance radars in traffic applications, the host computer is usually used to observe the target. The host computer can set the number of lanes and lane width. However, due to the ever-changing lane information in practice, the host computer cannot consider it comprehensively, and the host computer usually cannot accurately draw it. Lane, which makes the use of radar, only the distance, speed and angle of the target can be measured, and the lane where the vehicle is located cannot be accurately located, so it is necessary to locate ma...
