measurements have been "complex" and "the time required for measuring [has been]
long." (Id. at 2.)
Accordingly, the object of the appellants' invention is to measure 3-D data on a
"target" around the entire circumference thereof "at high speed using a relatively simple
configuration. . . ." (Id. at 3.) More specifically, the target is placed in an interior space
of a rotator type mirror. Reference light is projected toward the mirror from a position
on the center axis of thereof. The target is scanned with reference light reflected from
the mirror. 3-D data describing the target are obtained based on the projection angle of
the reference light and on the position of a projected image obtained when the reflected
light that scanned the target is captured by an imaging apparatus via the mirror. (Id.
at 3-4.)
A further understanding of the invention can be achieved by reading the following
claim.
22. A three dimensional information measurement apparatus for
measuring three dimensional information on a target, comprising:
a mirror having mirror surface facing to a space in which the target
is placed;
a reference light projection apparatus for projecting reference light
to the target placed in the space via reflection of the mirror surface;
an imaging apparatus for imaging the reference light on the target
via reflection of the mirror surface; and
