Abstract
A method and system for creating geometry for ADAS are described. Link chains, which are a sequence of segments, are created. The link chains are used to create 2D splines. The link chains, the 2D splines, and height data are used to create 3D splines. The 3D splines and possibly the 2D splines are converted to Bezier curves, which can be used to create a 2D polyline. ADAS applications can use the Bezier curves and the 2D polylines to provide ADAS functions.
