IPC: G01C15/06
Filed: 2002-07-18
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems that a pole fitted with a reflection prism cannot be installed at an external corner/ a reentrant corner/ a wall face, etc., that a measurement assistant is necessary since measurement cannot be performed by one person because a prism with a probe, etc., has to be used which is hard to be fixed with a tripod, etc., and that observation is difficult when a set point cannot be collimated even if the the number of set points is small.  <P>SOLUTION: Two prisms, etc., are connected by one component, and an aiming point, a first reflection prism and a second reflection prism are quantitatively disposed. Positioning the aiming point at a target point makes it possible to set up two uniformly offset eccentric points. Since eccentricity distances between the two eccentric points and the target point and positional relation (eccentricity element) of eccentricity direction are fixed prior to the eccentricity, observation of the two points and conversion of them into coordinates capacitate the target point to be easily calculated in a center-regressive manner on the coordinates.  <P>COPYRIGHT: (C)2004,JPO
