A preferred shape measuring apparatus comprises a characteristic pattern extracting portion (5) for calculating, in accordance with a pair of first images (51) of a subject (0) for measurement having characteristic patterns serving as references provided thereon in different angles and a pair of second images (52) of the subject (0) for measurement having no characteristic patterns serving as references provided thereon in the same angles as with the first images (51), the difference between the first image (51) and the second image (52) taken in each direction, thereby obtaining the characteristic patterns (54), a positional relationship calculating portion (6) for obtaining a positional relationship between the pair of the first images (51) or the pair of the second images (52) on the basis of the difference images obtained in the characteristic pattern extracting portion (5), a stereo model forming portion (7) for mutually relating in accordance with the positional relationship obtained in the positional relationship calculating portion (6), the first images (51) or the second images (52) so that a stereo model capable of being stereoscopically viewed is formed, and a shape measuring portion (8) for obtaining the shape of the subject (O) in accordance with the stereo model formed in the stereo model forming portion (7) (Fig. 2). <IMAGE> |
