PROBLEM TO BE SOLVED: To provide a method capable of accurately measuring a gap between coils despite the existence of light reflection due to the coils.SOLUTION: Light irradiation means applies striped pattern light to a stator while moving the light, and imaging means obtains a plurality of luminance distributions by imaging the stator multiple times. An integrated value of difference of the luminance for each pixel in the luminance distribution is calculated. When the integrated value exceeds a threshold, a part of the stator, which corresponds to the pixels for which the integrated value is calculated, is determined as a gap between coils, so that the gap is measured. |
