Abstract
A method of measuring a three-dimensional shape of a connection assembly of a stator coil in a turbine generator, includes first measuring a three-dimensional shape of a measurement area of the connection assembly of the stator coil in a measurement range set in advance by a laser non-contact three-dimensional shape measurement device, second measuring a three-dimensional shape of a measurement area of the connection assembly of the stator coil in a measurement range set in advance by a multi-joint contact three-dimensional shape measurement device, the multi-joint contact three-dimensional shape measurement device including a plurality of arms being coupled via a joint including a built-in encoder, and integrally synthesizing the three-dimensional shape data measured in the first measurement, the three-dimensional shape data measured in the second measurement, and shape measurement data of a local area measured manually, thereby drafting a plan of the stator connection assembly.
