    • 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.
    • 公开了一种在汽车定位和电子地平线应用中使用贝塞尔曲线的方法和系统,用于向先进的驾驶员辅助系统(ADAS)应用提供数据。 贝塞尔曲线从B样条获得。 获得的贝塞尔曲线以允许车辆定位应用实时导出折线表示的方式被细分。 使用Bezier和折线几何,车辆定位应用提供了对ADAS应用的车辆位置近似。 使用贝塞尔曲线,电子水平应用为ADAS应用提供曲率,斜率和航向分布。
