This paper discusses a measurement for strain distribution on girdles using motion image analysis. The proposed method allows dynamic measuremertt of the strain distribution by non-contact measurement that does not affect subjects. In order to evaluate the strain distribution on the girdles, the methods of calculating tensile strain, shear strain and rotation by discrete displacement vector fields are explained. In experiments, we observe that a subject wearing the girdle drawn grid pattern raises the left leg. Grid pattern deformation provides discrete displacement vector fields, so that tensile strain and shear strain are obtained. Principal strain calculated by tensile strain and shear strain on the girdle shows changes of strain distribution after raising a leg. Consequently, it is confirmed that the girdle at the waist is strained when the subject starts to raise the left leg.
