1. A data processing device that processes measurement data measured by a sensor that measures three-dimensional coordinates of a measurement object from a first position and a second position which are different, comprising:
a controller that:
acquires measurement data of three or more planes of the measurement object from the sensor, the planes having different normal vectors as a result of a change of orientation of the measurement object relative to the sensor, and
finds, from the acquired measurement data, a transformation expression that integrates a coordinate system of the sensor at the second position into a coordinate system of the sensor at the first position;
wherein during operation, the measurement object is moved, and wherein a visual field of the sensor at the first position and a visual field of the sensor at the second position overlap.
