PROBLEM TO BE SOLVED: To compose accurately, inexpensively and automatically the whole peripheral model by using a shape measured from a plurality of directions. SOLUTION: This device is constituted of a three-dimensional coordinate acquiring device 3, a rotary table 2, a plurality of calibration rods 7, and a control system 100. The rotary table 2 is provided with a plurality of recessed parts 11. The three-dimensional coordinate acquiring device 3 acquires a plurality of three-dimensional coordinates on a subject 1 and acquires three-dimensional shape information. The subject 1 is arranged on the rotary table 2, and the calibration rods 7 are mounted in an arrangement enclosing subject 1 by using a recessed part 11. A plurality-of-times measurement control part 101 controls so that the subject 1 or the like is measured in a plurality of times from different viewpoints by the three-dimensional coordinate acquiring device. A calibration rod recognition part 102 specifies which calibration rod is a calibration rod related to imaging from three-dimensional coordinate data of the calibration rods. A coordinate conversion parameter calculation part 103 calculates a coordinate conversion parameter at the viewpoint from the three-dimensional coordinate data of the calibration rods and arrangement information of the specified calibration rod. A coordinate conversion part 104 converts the three-dimensional coordinate data in a local coordinate of a measuring object acquired from the viewpoint into, for example, a world coordinate.
