Abstract
A computer-implemented method for determining the position of a lift cabin in a lift shaft with the aid of a coding device, in which method is at least one of a section of the code band and the bearing device is recorded with an optical detection device as a pixel image in which the pixel image is larger than the position marker, the pixel image is processed and a binary code is decoded by means of an algorithm and converted into a position indication, a checksum of the position marker, which is formed by at least one of the binary code and grayscale values of the position marker, is compared to a predetermined value, and one of a barcode and a 2D code calculated from the position indication using an inverse of the algorithm and is compared with at least one recorded row outside of the position marker.
