DETERMINING A MARK IN A DATA RECORD WITH THREE-DIMENSIONAL SURFACE COORDINATES OF A SCENE, CAPTURED BY AT LEAST ONE LASER SCANNER

摘要

A method for determining a mark in a data record with three-dimensional surface coordinates of a scene includes ascertaining a first collection of edge points in a three-dimensional coordinate system of the data record, fitting an equalization area into at least a subset of the edge points of the first collection of edge points to permit the edge points in the three-dimensional coordinate system to be partly positioned on a first side of the equalization area and partly positioned on a second side, lying opposite the first side, of the equalization area, displacing edge points of the first collection of edge points into the equalization area to permit a corrected collection of edge points to be formed, and determining the mark in the three-dimensional coordinate system based on the corrected collection of edge points or the corrected closed circumferential edge line.
