METHOD AND MEASURING SYSTEM FOR SENSING A FIXED POINT NEXT TO A TRACK

摘要

A method of determining the actual position of a track relative to a fixed point located in a lateral vicinity of the track by using a registering device being mobile on the track includes surveying the position of the fixed point relative to the track. The registering device is moved along the track, image pairs of the lateral vicinity of the track are continuously recorded by a stereo camera system on the registering device and the fixed point is searched for in the image pairs by pattern recognition carried out in an evaluation device. Upon recognition of the fixed point, the position of the fixed point relative to the track is determined by evaluating at least one image pair. This creates the possibility of surveying fixed points in passing with the configuration of the fixed point not being bound to any special form. A measuring system is also provided.
