Abstract
The present disclosure provides a groove shape measuring method and a groove shape measuring apparatus, capable of achieving reduction in processing load and acquisition of a more accurate cross-sectional profile. The groove shape measuring method includes: a setting step of dividing a processing groove into a plurality of measurement regions with a predetermined pitch and further setting, for each of the measurement regions, N number of sub-measurement regions in the measurement region; a coordinate data acquisition step of acquiring a plurality of coordinate data on the processing groove in respective M-th sub-measurement regions in the measurement regions; and a cross-sectional profile generation step of generating a cross-sectional profile by projecting the coordinate data, corresponding to the M-th sub-measurement regions acquired for the respective measurement regions in the coordinate data acquisition step, onto a two-dimensional plane.
