PROBLEM TO BE SOLVED: To provide an analysis method for a beauty treatment effect which is a method deriving a distortion distribution of the skin of the face by using an image photographed before and after the treatment, having this distortion distribution as evaluation index and not needing coating of paint etc., pattern on the face of a subject in the method for quantitative analysis of the effect of a beauty treatment for the face such as a facial massage.SOLUTION: An analysis method of a beauty treatment effect for evaluating the effect of the beauty treatment is a method for analysing the effect of the beauty treatment by using at least two images photographed before and after the beauty treatment to the face of the subject and: uses images used for the analysis, which are at least two ultraviolet ray photographs photographed before and after the beauty treatment derives a three dimensional shape of the face of a subject and a displacement distribution by using a stereo image correlation method as melamine pigments appearing in the ultraviolet ray photograph as a random pattern derives distortion distribution by differentiating the displacement distribution along a surface shape of the face and uses the acquired distortion distribution as an evaluation index.SELECTED DRAWING: Figure 21COPYRIGHT: (C)2017,JPO&INPIT【課題】フェイシャルマッサージ等の顔面に対する美容施術の効果を定量的に解析する方法において、施術の前後に撮影された画像を用いて、顔面の皮膚のひずみ分布を求め、このひずみ分布を評価指標とする方法であって、被験者の顔面に対する塗料等パターンの塗布を必要としない美容施術効果の解析方法を提供する。【解決手段】被験者の顔に対する美容施術の前後に撮影された少なくとも2枚の画像を用いて、美容施術の効果を解析する方法において、解析に用いられる画像が、美容施術の前後に撮影された少なくとも2枚の紫外線写真であって、この紫外線写真に表れたメラニン色素をランダムパターンとして、ステレオ画像相関法を用いて、被験者の顔面の三次元形状と、変位分布をそれぞれ導出し、前記変位分布を顔面の表面形状に沿って微分することでひずみ分布を導出し、この得られたひずみ分布を評価指標として、美容施術の効果を評価する美容施術効果の解析方法。【選択図】図21
