Abstract

An edge detection system for a road paver, wherein the edge detection system includes a sensor unit, which is configured to emit laser pulse sequences into a plurality of directions in such a way that the laser pulse sequences are reflected at a plurality of locations of a surface to be scanned. The sensor unit is further configured to detect reflections of the laser pulse sequences and, based on the detected reflections, generate polar coordinate signals representing polar coordinates, wherein the polar coordinates include a distance and an associated angle. The edge detection system is configured to transform the polar coordinate signals into Cartesian coordinate signals representing Cartesian coordinates and to determine a position of an edge in the surface to be scanned relative to a Cartesian coordinate system based on the Cartesian coordinate signals.
