A method for storing height profile data, as well as profile data and a method for generating a height profile of these profile data

摘要

The invention relates to a method for storing of profile data for a predetermined height profile, comprising the steps of:(a) providing a regular grid (1) with a polygonal half-tone fields (2) of a first levels in a plane, wherein corner points (3) of the grating elements (2) represent screen dots, and to each screen dot is stored a height value,(b) determining an error value for each grating element (2), of a deviation of a by the height values of the grid (2) is approximated height profile from the predetermined height profile describes,(c) of the raster fields (2), the error value exceeds a predetermined threshold value, in polygonal part grids (4, 5), wherein at least to the corner points (3) of the part grids (4, 5) which do not coincide with corner points (3) of the grating elements (2) together, altitude values are stored,(d) assigning in each case of an indicator with each raster field (2), wherein the indicator describes whether the grating element (2) is divided or not, and storing these indicators, together with the height values, and(e) repeating steps (b) to (d) for all part grids (4, 5), wherein the part grids (4, 5) of an i-th levels grating elements (2) of a i + 1th level, the height values are stored in a predetermined sequence, so that the height values due to the sequence in each case to a specific corner point (3) of the grid field (4, 5) are assigned, and by means of the indicators of a jth levels is determined, for which the corner points (3) of the j + 1th levels height values are stored.
