Railway vision is an important image processing application in which pictures taken from the front of a train are used to support operational control and inspect wayside facilities. We evaluated picture-taking systems using a space and picture model - the imaginary tunnel model - in which railway space is modeled as an imaginary rectangular tunnel including a construction gauge. Position criteria and camera direction are studied based on the visible tunnel zone. We also estimated position and direction based on rail loci in camera pictures.
