| 摘 要： | 道路交通标线信息是道路导航地图中必不可少的数据，对于制作精度更高、道路细节信息更加丰富清晰的高精度导航地图具有重要的作用。本文以车载近景立体影像中的道路交通标线信息自动提取为研究目标，针对道路交通标线快速、精确采集的应用需求，提出了基于几何规则的车载近景立体影像道路交通标线自动提取方法。该方法首先分析了道路交通标线的几何特征；其次，构建了基于几何特征的交通标线信息提取规则；最后，以标线种子点为基础，结合前述规则，实现了道路交通标线三维空间信息的自动采集。以南京师范大学的车载移动测量系统拍摄的实际近景立体影像为数据进行了试验，试验结果证明，本文方法相比传统人机交互采集方法，在交通标线特征点采集效率、标线几何相似度等方面有较大的优势，可为高精度导航地图的生产提供一种可借鉴的技术支撑。

| Abstract: | Road traffic marking is an indispensable data in road navigation maps, which plays an important role in making high-precision maps, and navigation maps with higher accuracy, richer and clearer road detail information. The automatic extraction of road traffic marking information in vehicle-borne close-range stereo images is taken as the research target in this paper. For rapid and accurate collection of road traffic marking, an automatic extraction method is proposed based on geometric features. Firstly, the geometric features of road traffic marking are analyzed. Secondly, the extraction rules of traffic marking are constructed based on geometric features. Finally, combined with the foregoing rules, the automatic collection of three-dimensional spatial information of traffic marking is realized based on the seed points. The close-range stereo images collected by mobile measurement system of Nanjing normal university have been carried out to verify the experiment. The experimental results prove that this method compared with the traditional human-computer interaction collection method, has mere advantages in collection efficiency of traffic marking feature points and the geometric similarity of marking. This method approved it provides a technical support for the production of high precision navigation map for reference. |
