Abstract: A three-dimensional measurement device includes: an optical system including an optical device that splits an incident light, irradiates a measurement object with a measurement light, irradiates a reference plane with a reference light, and combines at least part of the reflected measurement light with at least part of the reflected reference light to emit a combined light; a first light emitter that emits a first light that has a first wavelength; a second light emitter that emits a second light that has a second wavelength; a first imaging device that takes an image of an output light output from the optical device in which the first light enters; a second imaging device that takes an image of an output light output from the optical device in which the second light enters; and a control device that executes three-dimensional measurement of the measurement object.
