Abstract: The present invention relates to a method and a system for generating a 3D manipulated image acquired by combining physical data and clothing data, and more particularly, to a method and a system for generating a 3D manipulated image acquired by combining physical information of a user, data acquired by scanning clothing, and unique information of fabric used in making the clothing. To this end, a method for generating a 3D manipulated image by combining data acquired by clothing with data acquired by scanning a body of a user includes: adjusting a distance between clothing cloud data by combining physical cloud data representing a body of a user, clothing cloud data representing clothing, unique information of fabric constituting the clothing, and the unique information of the clothing; generating 3D manipulated data acquired by synthesizing the body and the clothing of the user; and generating a contour line from the 3D manipulated data and generating colors to generate the 3D manipulated image.
