Abstract
1. Method of identifying articles, which appear in any position and orientation and at any time at an image aperture and each have a designating area or panel on a surface which is facing the image aperture, which panel comprises symbols (52) in at least one datum track (51) and at least one contrasting line pattern (54), which characterizes the positon and the orientation of the datum track and has a plurality of parallel lines of different spacing and/or line width, in connection with which the image aperture is scanned line by line (60) and a binary video signal corresponding to the scanned contrast line pattern and the following symbols is produced, the image aperture in the first step of the method being scanned at different angles until a prescribed contrasting line pattern is detected, in the second step of the method, the position alignment of the data track relatively to the image aperture is established, and in the third of the method, a grid scanning is effected in the direction of the data track and the symbols are read off and decoded, characterized in that, - for the detection of the constrast line pattern (PIC), the interval lengths of overlapping intervals (Figs. 11 to 14) of the video signal and in each case comprising at least one light-dark region are measured and portrayed in the form of binary counter readings (TC1 to TC4), - that the counter readings (TC1 to TC4, Fig. 6) address a two-dimensional table (Fig. 10) which is stored in a store (28 in Fig. 7) and in which is contained an expectation zone with criteria for a prescribed ratio between two successive interval lengths of the intervals (11 to 14), - that the counter reading (TCN) corresponding to an interval length (IN) addresses one line of the table and the reading corresponding to the following interval length (IN+1) addresses one column of the table, - that a coincidence signal (LPIC1, LPIC2, LPIC3) is produced when the relation of the two respectively following interval lengths lies in a prescribed value range, and - that a recognition signal (PIC OUT Fig. 9) is delivered when a coincidence signal (LPIC1, LPIC2, LPIC3) is produced with a number of successive addressing steps which is prescribed by the contrast line pattern (PIC).
