Self-orientation system, used in underground tunnels, couples information from fixed sources with three-dimensional visualization model stored in computer

摘要

Information carriers (2), e.g. transponders or bar-codes, attached to the tunnel structure, contain a representation of the local coordinates. A reader extracts this information and a computer processes it, coupling it with a stored 3-D visualization of the tunnel or mine structure. A monitor displays the location determined. An Independent claim is included for the corresponding method.
