Problems solved by technology

[0004] However, when the applicant researched the existing technology, it was found that due to inconsistent factors such as maintenance and design on daily roads, the lane lines on some roads do not exist, such as tunnels, mountain roads, etc. On the road with lane lines, the lane lines cannot be recognized, which will bring safety hazards to self-driving vehicles

Abstract

The present invention discloses a lane line simulation method and device, and a storage medium. The method comprises the steps of: obtaining point cloud information of a laser radar; based on the point cloud information, determining multi-group laser points meeting wall features; determining one lane line candidate point from each group of the laser points; and according to the lane line candidatepoints, simulating and generating the lane line around the vehicle. Based on the method, in the vehicle running process, even though there is no lane line on the road or the lane line is damaged andcannot be identified, the laser emitted by the detection laser is detected to perform rapid and accurate simulation of the lane line around the vehicle in real time.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, and in particular to a lane line simulation method, device and storage medium. Background technique [0002] With the rapid development of the automobile industry, the automobile has gradually become an important means of transportation for people to travel, but it is accompanied by the problem of urban road traffic safety. The high number of road traffic safety accidents leads to an increase in the number of casualties caused by traffic accidents every year. Automobile safety is closely related to three factors: the environment, people, and vehicles. Among them, the human factor is the most important. Once people cannot maintain attention, or process road information slowly or even make mistakes, it may lead to driving errors and even car accidents. Relevant research and investigations have found that the driver's behavioral ability plays a decisive role in the process of dri...
