A condition analysis apparatus capable of grasping the condition of an
object easily and accurately is provided. The condition analysis
apparatus 1 includes a three-dimensional sensor 10 for measuring
sampling-point-moves in the height direction of an object 2 existing in a
target area at a plurality of sampling points, and area definition means
22 for defining an area where a plurality of the sampling-point-moves are
in the generally same phase. The thus constructed condition analysis
apparatus 1 can grasp the condition of the object 2 easily and
accurately. Preferably, the condition analysis apparatus 1 includes
information output means 40 for outputting information of an area
including the area defined by the area definition means 22.
