Generation of High Precision Digital Maps using Circular Arc Splines

Digital maps can provide essential information for many advanced driver assistance systems (ADAS) dedicated to both safety and comfort applications. As the level of detail and global accuracy of state-of-the-art digital maps are not sufficient for a multitude of applications, we present methods and models for the generation of high precision maps. The proposed modeling includes 3D lane level information, road markings, landmarks and additional attributes with benefits for many ADAS. The extensive use of circular arc splines enables both adjustable accuracy and high efficiency as our cartographic methodology guarantees the minimum number of curve segments with respect to a given error threshold.
