Abstract

A method and system for using Bezier curves in vehicle positioning and electronic horizon applications for providing data to advanced driver assistance systems (ADAS) applications are disclosed. The Bezier curves are obtained from B-splines. The obtained Bezier curves are subdivided in a manner that allows the vehicle positioning application to derive a polyline representation in real time. Using the Bezier and polyline geometry, the vehicle positioning application provides a vehicle position approximation to the ADAS applications. Using the Bezier curves, the electronic horizon application provides curvature, slope, and heading profiles to the ADAS applications.
