Apparatus for obtaining three-dimensional shape data of an object including a controller for controlling a light beam, a scanning system for scanning an object by the controlled light beam, and an image receiving system for receiving the light reflected from the object in a prescribed range. A memory stores data for correction of illumination irregularities corresponding to positions in the prescribed range that the light reflected from the object is received, and the controller refers to the stored data according to the position where the reflected light is received by the image receiving system, in order to control the light beam used by the scanning system.
