Creating geometry for advanced driver assistance systems

摘要

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.

1. A method comprising:
identifying one or more two-dimensional curves for a plurality of segments that represent a portion of a road network; calculating, by a processor, a three-dimensional spline curve from the one or more two-dimensional curves and height data; and storing the three-dimensional spline curve in a database, wherein a driver assistance application is configured to incorporate the three-dimensional spline curve to affect vehicle operation.
