| 摘要 |
The present invention provides a method of measuring a shape of a target surface, including a step of obtaining shape data by causing a stage which holds the target surface to rotate the target surface about a rotation axis, positioning each of a plurality of partial regions of the target surface in a field of view of a measurement apparatus, and causing the measurement apparatus to measure each of the plurality of partial regions, a step of obtaining, for each of a plurality of partial contour regions, a central position of the target surface using data of a contour included in the shape data, and a step of obtaining, based on the obtained plurality of central positions, a position of the rotation axis of the target surface in positioning each of the plurality of partial regions.
