A new method that can recover 3D information of an object with plane symmetry from single view image is shown here. This method is available for perspective images; camera images and sketches. From the perspective relation of an image and symmetric points, 2 or 3 vanishing points, camera position, and symmetric plane are derived. And the 3D positions of all the symmetric points are decided by using the geometrical relation of the vanishing points, the camera position and the symmetrical plane. Here, the process for hiden points is also shown.
