Extracted and classified road markings from a mobile lidar dataset collected in Philomath, OR.

The dataset is an annotated point cloud in ASPRS LAS v1.2 format, which is annotated with different classification numbers representing six different road markings, including lane markings (1), pedestrian crosswalk and text (2), bike (3), left arrow (4), right arrow (5), straight arrow (6), and others (0). The point cloud dataset was obtained using Oregon Department of Transportation current mobile lidar system (Leica Pegasus:Two). The data were georeferenced in the supporting software for the Leica Pegasus:Two by Oregon DOT. The authors processed the data to extract the road markings using the road marking extraction tool (Rome2) developed in this Pactrans research.

本数据集为采用ASPRS LAS v1.2格式标注的点云数据，通过不同分类编号标注六种道路标线类别，具体包括车道线（1）、人行横道及文字标线（2）、自行车道标线（3）、左转箭头标线（4）、右转箭头标线（5）、直行箭头标线（6）以及其他类别（0）。该点云数据集由俄勒冈州交通局（Oregon Department of Transportation，简称ODOT）当前使用的移动激光雷达系统徕卡（Leica）Pegasus:Two采集获取，数据已由该局借助该系统的配套支持软件完成地理配准。本文作者通过本Pactrans研究项目中开发的道路标线提取工具Rome2，对原始数据进行处理以提取道路标线。
