First, as a step (S100) of receiving an input from the user of the shooting distance R between the subject and the camera and the shooting angles θ of the plurality of cameras for the subject (S100), the user operating the system starts driving the system, and his/her intention In order to obtain a 3D scan image for each body surface of a subject, a shooting distance (R) between the subject and the camera and a shooting angle (θ) of the camera at each point may be input to the system.
