Problems solved by technology

[0005] 2. The left and right directions of the front-view camera can effectively identify the lane line. The distance is only 2.5~3 meters, so when the vehicle crosses the lane line, it cannot recognize the lane line on the other side
[0006] That is to say, the current AVM-based LDWS will have the problem of missing identification and resulting in missing alarms, which may cause safety accidents

Embodiment Construction

[0027] The present invention discloses a realization method of LDWS lane line recognition and tracking based on AVM camera, which utilizes AVM's front-view camera, left-view camera, right-view camera and rear-view camera in combination with adjacent frame images for lane line recognition and tracking. Tracking, which is as follows:

[0028] (1) When the vehicle is driving normally in a lane, if the lane line cannot be recognized in the current frame image captured by the front-view camera, judge whether the lane line can be recognized in the current frame image captured by the left-view camera and the right-view camera.

[0029] If the current frame image captured by the left-view camera and the right-view camera can recognize the lane line (such as figure 1 The scene shown), first call the previous frame image of the front-view camera, and extend the lane line in the previous frame image of the front camera backward to form an extended area; then use the left-view camera and ...

Abstract

The invention discloses an implementation method of LDWS lane line recognition and tracking based on an AVM camera. Lane line identification and tracking are carried out through the front-view camera,the left-view camera, the right-view camera and the rear-view camera of the AVM in combination with adjacent frame images, so that the problem of lane line identification missing in the prior art iseffectively solved, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, in particular to an implementation method of LDWS lane line recognition and tracking based on an AVM camera. Background technique [0002] With the increasing popularity of automobiles, people pay more and more attention to driving safety. The 360-degree panoramic video system (AVM) realizes driving without blind spots, and the lane departure warning system (LDWS) provides intelligent lane departure warning. [0003] At present, when LDWS and AVM are combined together, LDWS generally only utilizes the front-view camera of the AVM system. Through observation, the following problems exist in the current LDWS reuse process: [0004] 1. The front-view camera can effectively identify the lane line at a distance of only 7-8 meters, so the lane line ahead cannot be seen at the distance of 9 meters from the white dotted line. [0005] 2. The left and right directions of the front-vie...
