Abstract
The commercialization of automated driving vehicles promotes the development of safer and more efficient autonomous driving technologies including lane marking detection strategy, which is considered to be the most promising feature in environmental perception technology. To reduce the tradeoff between time consumption and detection precision, we propose a real-time lane marking detection method by using LiDAR point clouds directly. A constrained RANSAC algorithm is applied to select the regions of interest and filter the background data. Further, a road curb detection method based on the segment point density is also proposed to classify the road points and curb points. Finally, an adaptive threshold selection method is proposed to identify lane markings. In this investigation, five datasets are collected from different driving conditions that include the straight road, curved road, and uphill, to test the proposed method. The proposed method is evaluated under different performance metrics such as Precision, Recall, Dice, Jaccard as well as the average detection distance and computation time for the five datasets. The quantitative results show the efficiency and feasibility of this proposed method.

Summary
Self-driving technologies have received much attention due to the several research activities of universityindustry collaboration financed by some reputed companies such as Waymo [1] and Hyundai [2]. The realization of autonomous driving technology is difficult. The most basic yet important function for an automated vehicle is environmental perception, because of its direct influence on both drivers and pedestrians. Various objects need to be recognized in the procedure of environmental perception, such as lane markings, pedestrians, and adjacent vehicles. Different sensing modalities are used to achieve autonomous driving, for example, visual and thermal cameras, radars, Light Detection and Ranging (LiDAR) sensors, and ultrasonic sensors.
