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.

Bezier curves for advanced driver assistance system applications

A system and method includes reception of a first image data value of a digital image, determination of a first index based on the first image data value, determination of a value stored in a first array of a first shared memory at the first index, and determination of whether the value stored in the first array of the first shared memory at the first index is equal to the first image data value. If the value stored in the first array of the first shared memory at the first index is equal to the first image data value, 1 is added to a count value stored in a second array of the first shared memory at the first index. If the value stored in the first array of the first shared memory at the first index is not equal to the first image data value a count value stored in a second shared memory in association with the first image data value is updated.

System for histogram computation

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.
