Abstract: A method for transforming between physical and virtual images includes: disposing an image capturing device at a position that does not coincide with line-of-sight of a user; providing at least three physical distance references on the line-of-sight of the user at different distances from the user, and capturing images of the at least three physical distance references by the image capturing device so as to obtain an epipolar line formed by at least three virtual distance references corresponding respectively to the images; and obtaining a first relation by a computing unit according to a position corresponding relationship between the at least three physical distance references and the at least three virtual distance references. By using the image capturing device that is at a fixed position relative to the user and does not coincide with the line-of-sight of the user, the physical position of an object is obtained.
