A method for positioning of a scanner relative to a coded surface and scanner, in particular for reading bar codes, two-dimensional codes and color codes

摘要

A method for positioning of a scanner (1) relative to a coded surface (5), characterised thereby, wherein a projector (4) or a plurality of projectors which in each case in a fixed distance to a scanning device (3) are positioned, signals (6) are transmitted in the region of the coded surface (5) are reflected, and the reflected signals with the scanning device (3) are detected and with a predetermined signal are compared and the deviation of a projected line and surface area of the reflected geometry as a measure for the angular arrangement of the scanner relative to the surface to be used.
