Abstract
A rotating electric machine includes a stator and a rotor. An imaging device images a test target portion which is a part of the rotor, to generate image data of the test target portion, and transmits the generated image data to an image processing device. The image processing device generates strain change information representing change in the strain distribution in the test target portion by digital image correlation on the basis of the test image data generated by the imaging device. The state of the rotor is tested using the generated strain change information.
