Abstract
In order to increase safety, a computer-implemented method is proposed for determining the position of a lift cabin in a lift shaft with the aid of a coding device, wherein a section of the code band and/or of the bearing device is recorded with an optical detection device as a pixel image consisting of pixels and the instant of the recording being measured and assigned to the pixel image, wherein the position is determinable analytically from position markers of the code band by way of an algorithm and wherein at least one checking method which uses, inter alia, a calculated extrapolated position is carried out.
