Two-dimensional lattice calibrating device, two-dimensional lattice calibrating method, two-dimensional lattice calibrating program and recording medium

摘要

A two-dimensional lattice calibrating device includes: a measuring unit (2) that measures respective positions of marks (1a) for each of a plurality of measurement dispositions (n); a simultaneous-equations generating unit (5) that generates simultaneous equations for acquiring deviations (Di) of the plurality of marks (1a) using a coordinate relational equation and a least-squares conditional equation that sets least-squares lines that minimize the deviation (Di) of actual position (Li) of the marks (1a) based on measurement values (mni) as coordinate axes of artifact coordinates; and a simultaneous-equations calculating unit that solves the derived simultaneous equations.
