In a measurement processing apparatus for measuring a geometric feature of
an object image: a measurement-reference-element setting unit
automatically sets at least one first measurement reference element for
use in measurement of the geometric feature of the object image, at at
least one first position on the object image based on first image data
representing the object image and position information indicating at
least one second position of at least one second measurement reference
element which is set on a measurement reference image corresponding to
the object image; and a geometric-feature measurement unit measures the
geometric feature of the object image based on the at least one first
position of the at least one first measurement reference element.
