PROBLEM TO BE SOLVED: To dispense with measurement for a calibration tool or the like in advance to measurement, when composing three-dimensional coordinates in a plurality of view points, and to preclude the view points for measuring an object from being limited only to simple one-axial rotation. SOLUTION: This instrument is constituted of a three-dimensional coordinate acquiring device 1, an arranging part 2, plate-like members 31-36, and a control system 100. The three-dimensional coordinate acquiring device 1 acquires the plurality of three-dimensional coordinates on the measuring object to obtain information of a three-dimensional shape. The plate-like members are preliminarily fixed in the arranging part 2, and the measuring object is arranged on the arranging part 2. A plurality-of-measurements control part 4 controls the measuring object or the like to be measured at a plurality of times of the measurements from the different view points by the three-dimensional coordinate acquiring device 1. A plate-like member recognition part 5 specifies, for example, the plate-like member concerned in image pick-up, based on a three-dimensional coordinate data of the plate-like member. A coordinate transformation parameter calculating part 6 calculates a coordinate transformation parameter in the view point, based on the three-dimensional coordinate data of the plate-like member and arrangement information of the specified plate-like member. A coordinate transformation part 7 transforms the three-dimensional coordinate data of local coordinates of the measuring object acquired in the view point, for example, into world coordinates.
