ABSTRACT:
A three-dimensional shape measuring apparatus includes a moving frame arranged to surround a measurement space. The moving frame is arranged to be movable in a vertical direction. A plurality of sensors is disposed opposite to each other on two opposite sides of the moving frame and are arranged to effect a horizontal scanning of light to measure distances to a human body being measured. A driving mechanism moves the moving frame. An analyzer calculates distances to the human body, based on output signals from respective sensors, to analyze data of a surface position of the human body, i.e., a three-dimensional shape thereof. The apparatus further includes a placement state on which the human body is placed. Since the sensors are located so as to face the front and the back of the human body, the apparatus can also measure portions below an armpit and below a crotch.
