Title:
METHOD AND APPARATUS FOR MEASURING POSITION AND ATTITUDE OF TUNNEL BORING MACHINE
Document Type and Number:
WIPO Patent Application WO/1997/008429
Kind Code:
A1
Abstract:
A method and an apparatus for measuring the position and attitude of a tunnel boring machine, capable of accurately measuring the position and attitude of a tunnel boring machine by reliably detecting the position and attitude thereof in a relay measuring point. According to this method, a relay measuring point C set on a carriage is provided between a reference measuring point A and a mobile body measuring point B, and the position and attitude of a tunnel boring machine in operation are measured on the basis of the data in the reference measuring point by moving and stopping the carriage to and in a position, to which light emitting from the reference measuring point A can reach, when the operation of the machine is stopped, and by receiving the light emitting from the reference measuring point A in the relay measuring point C and mobile body measuring point B when the operation of the machine is carried out.
