Abstract

The invention discloses a lane line detection system and method. The system comprises a camera signal acquisition module, a laser radar signal acquisition module, a space-time registration module, a camera signal preprocessing module and a multi-task lane line detection module. According to the invention, information of a laser radar and a camera is fused, and a lane line detection task under the change of illumination conditions can be adapted; a lane line detection model is established by using a multi-task thought, and the lane line position is determined and the type of the lane line is identified, so that the network efficiency is improved, and the resource configuration is optimized.

Description

technical field [0001] The invention belongs to the technical field of intelligent driving, and in particular relates to a lane line detection system and method. Background technique [0002] With the increasing number of cars, road traffic tends to be denser and more complicated, which leads to an increase in driving pressure, which reduces the driving ability of drivers in normal traffic scenarios and greatly increases the probability of traffic accidents. Among them, lane-changing behavior is one of the important causes of traffic accidents and traffic congestion, especially in urban areas, where the traffic density is high, and lane-changing collisions are prone to occur, and even lead to serial rear-end collisions. Compared with human driving, the intelligent driving system has the advantages of short reaction time and high perception accuracy. Therefore, the study of intelligent driving technology is of great significance to reduce traffic accidents caused by human fac...
