The purpose of the present invention is to more quickly and easily measure the shape of an object to be measured. A shape measurement device includes: a probe including a projection optical system that projects a line-shaped pattern onto a surface of the object to be measured or projects a spot pattern while scanning in at least a linear scanning range, and an image capturing device that detects an image of the pattern projected onto the object to be measured; a movement mechanism that rotates the object to be measured and the probe relative to each other so that the object to be measured rotates relative to the probe around a rotation axis and moves at least one of the probe and the object to be measured relatively in a direction that intersects with a rotation direction in which the object to be measured rotates; a measurement region setting unit that sets a measurement region of the object to be measured; and an actual measurement region setting unit that sets an actual measurement region including an actu
