Apparatus for automatically setting measurement reference element and measuring geometric feature of image
First Claim
1. A measurement processing apparatus for measuring a geometric feature of an object image, comprising:
- a measurement-reference-element setting unit which automatically sets at least one first measurement reference element for use in measurement of said geometric feature of said object image, at at least one first position on said 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 which measures said geometric feature of said object image based on said at least one first position of said at least one first measurement reference element.

Abstract
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.

6. A measurement processing apparatus according to claim 11, wherein said measurement-reference-element setting unit searches for an edge in a vicinity of a third position on the object image corresponding to each of said at least one second measurement reference element, and automatically sets each of said at least one first measurement reference element based on information on the edge.
