Abstract
A position adjusting mechanismwith a targetmounted thereon is fixed at a plurality of reference points Sto Srespectively on a construction, and initial 3D coordinates Cof the targetsare surveyed and stored. When deformation or distortion of the constructionoccurs, a deviation ΔC (=Ct−C) of 3D coordinate Ct of each of the targetsfrom the initial 3D coordinate Cthereof are detected by a deviation detecting means, and each of the targetsrecovers the initial 3D coordinate Cby the position adjusting mechanismthereof in accordance with the detected deviation ΔC. Preferably, 3D coordinates of the targetsare surveyed by a 3D measuring instrument which collimates the targetsto output 3D vectors for the targets. The position adjusting mechanismmay includes guide stage for guiding the targetmounted thereon in a direction or in two directions that intersect at right angle, the direction or directions parallel to a surface F of the construction, and feed mechanism for sliding the targeton the guide stage in predetermined amount.
