Orbit measurement system and orbit measurement method

摘要

PROBLEM TO BE SOLVED: To perform the measuring of multiple items by a single measuring work.;SOLUTION: In a railroad track measuring gauge, two prism mirrors are attached to both sides of its gauge body. A first gauge body for fixing the first prism mirror has a left-hand side positioning part 14 for positioning with respect to a left-hand side rail 6, and a second gauge body for fixing the second prism has a left-hand side positioning part 24 for positioning with respect to a right-hand side rail 7. A station measures the relative position vector between both prisms by distance measurement using a laser. A single measurement gives data for computing a track value, level, passage. and height which are required for railroad track measurement. Consequently, measuring work becomes simple.;COPYRIGHT: (C)2005,JPO&NCIPI
