1. A method for determining a position of a rail vehicle, moving on a track, by means of an optical measuring system comprising:
using a stereo camera system and
using an evaluation device,
recording an image pair by means of the stereo camera system from a reference point in a lateral environment of the track;
determining the position of the rail vehicle by means of photogrammetry in relation to the reference point,
detecting the position of the rail vehicle by means of a radio-based measuring system for real-time locating by means of anchor modules attached to the rail vehicle, by means of transponders attached to several reference points and by means of a computer unit that is set up for the real-time locating by means of runtime determination and multilateration, particularly trilateration, and in that position data from the two measuring systems is compared by means of a central system unit.
