Claim:
1. A three-dimensional shape measurement apparatus that measures a coordinate of a surface of a target object based on a captured image including the target object onto which a pattern is projected, comprising: a projection unit configured to project a first pattern and a second pattern onto a measurement area in which the target object is placed and a reference marker is arranged, wherein the first pattern is a pattern for obtaining a coordinate of a surface of the target object and the second pattern is a pattern for correcting a projection position by the projection unit; an image capturing unit configured to capture an image of the measurement area onto which at least one of the first pattern and the second pattern are projected; and a control unit, including at least one processor, configured to: wherein the projection unit and the image capturing unit are fixed on a support structure and the position of the projection unit and the image capturing unit is changed by fluctuation of the support structure.
