A size measurement apparatus includes: a first light emitter unit for widely emitting light to an imaging area which may include an object; a second light emitter unit for locally emitting light to a part of the imaging area; an image taking unit for obtaining a range image which contains distance information on a pixel-by-pixel basis, with pixels being arranged two-dimensionally, the distance information being calculated based on a measured time value which is a time for the light emitted from the light emitter units to travel back as a reflected light; and an arithmetic control unit for controlling light emission from the light emitter units, and for calculating size information of the object based on a synthesized range image obtained by synthesizing a range image obtained during light emission from the first light emitter unit and a range image obtained during light emission from the second light emitter unit. |
