Abstract:
1. A form measuring device comprising: a measuring unit configured to detect a height at each position in a reference axis direction of a measured object and measure a cross-sectional form of the measured object, the reference axis being perpendicular to a height direction of the measured object; and an arithmetic unit configured to synthesize a plurality of form measurement data of the cross-sectional form obtained by repeated measurements of the form of the same measured object by the measuring unit, and calculate synthesized form measurement data, in the synthesis of the form measurement data of the cross-sectional form, the arithmetic unit being configured to calculate shift amounts between the form measurement data of the cross-sectional form and the synthesized form measurement data in the reference axis direction and the height direction and align the form measurement data in the reference axis direction and the height direction based on the calculated shift amounts.
