The method involves using at least two sensors (S1, S2) fastened in a distance to each other at an moving object, which register independently of each other a passing of the object along marks (M1... M3) which are arranged along the distance, whereby the distance between respectively two marks is determined. The points in time of the registering processes for each sensor are preferably stored in a memory, and a computer calculates the traversed distance and/or speed under consideration of the stored times and the distance between two sensors in movement direction. The distance between the two sensors is preferably as large as the distance between successive marks. |
