Abstract: A three-dimensional data generation method includes the following processing. A processor acquires two or more images of a component inside a turbine. The processor detects two or more correspondence regions that are the same regions in at least two images. The processor determines whether at least part of a region of each image is a change region or a non-change region. The processor generates three-dimensional data by using a correspondence region determined to be the change region without using a correspondence region determined to be the non-change region.
