When non-contact three-dimensional-shape measuring instruments that use probe light are used, first shape data for a measured object must be known when the operation trajectory of a measurement head is preset such that the probe light will be as perpendicular as possible when the probe light is incident on a measurement surface. A surface-shape measuring device that measures the surface shape of an object to be measured and that is provided with: a distance measuring apparatus that measures the distance to a measurement point on a surface of the object to be measured; an angle measuring apparatus that measures the slope at the measurement point on said surface; a first calculation unit that calculates basic shape data for the object to be measured on the basis of the distance measured by the distance measuring apparatus; and a second calculation unit that calculates detailed shape data for the object to be measured on the basis of the basic shape data and of the slope measured by the angle measuring apparatus. |
