a distance measuring section for measuring a distance to the object in each measuring direction of the scanning section; and

the measuring section measures the three-dimensional shape of the object based on the measured distance.

3. The three-dimensional shape measuring system according to claim 2 , wherein the measuring section calculates a distance to each point on the object, based on a flight time of a pulsed light from a transmitting time of a pulsed light to a receiving time of the pulsed light reflected from the object.

4. The three-dimensional shape measuring system according to claim 1 ,

wherein the information displayed is a message image indicating the status of progress of the scanning.

5. The three-dimensional shape measuring system according to claim 4 , wherein the message image is an image indicating a degree of progress of the scanning as a percentage.

6. The three-dimensional shape measuring system according to claim 1 , wherein the measuring section measures the area displayed by the display portion substantially uniformly.

7. The three-dimensional shape measuring system according to claim 1 , wherein the two-dimensional image of the object in the area where the scanning is finished includes information about a three-dimensional shape based on the measurement result.
