Abstract
The invention relates to a method for determining a position of a rail vehicle, moving on a track, by means of an optical measuring system comprising a stereo camera system and an evaluation device, wherein by means of the stereo camera system an image pair is recorded from a reference point in a lateral environment of the track and wherein by means of photogrammetry the position of the rail vehicle is determined in relation to the reference point. The position of the rail vehicle is additionally detected by means of a radio-based measuring system for real-time locating by means of anchor modules attached to the rail vehicle and by means of transponders attached to several reference points, wherein position data of the two measuring systems are compared by means of a central system unit. In this way, two independent measuring systems are used to generate position data.
