A three-dimensional shape measurement system includes an image pickup unit, a storage device that stores image pickup conditions required in imaging for measurement as condition information for each of a plurality of combinations of the material and surface property of an object, and a measurement controller that controls driving of the image pickup unit. The measurement controller identifies the material and surface property of the object, specifies image pickup conditions corresponding to the identified material and surface property of the object based on the condition information, causes the image pickup unit to perform the imaging for measurement under the specified image pickup conditions, and measures the shape of the object based on the obtained image for measurement.
