Image acquisition system for generation of three-dimensional models
First Claim
1. A photographic apparatus for taking images of an object for use in generating a three dimensional model of the object, the photographic apparatus comprising an object placing unit for placing the object, an image capturing unit for capturing images of the object for use in generating the three dimensional model, and an illumination unit, the image capturing unit and the illumination unit being connectedly moveable relative to the object placing unit such that, in use, the object may be placed by the placing unit both in the field of view of the image capturing unit and in a position where the illumination unit is capable of providing illumination for the image capturing device to take silhouette images of the object.

Abstract
A photographic apparatus and a method for taking images of an object for use in generating a three dimensional model of the object are described. The apparatus includes an object placement unit, an image capturing unit and an object illumination unit. The image capturing unit and the object illumination unit are connectedly moveable relative to the object placement unit so that in all positions of the image capturing unit and the illumination unit, the object can be placed on the object placement unit so that the illumination unit can be provide the illumination required for the image capturing unit to take silhouette images of the object.

15. A method of generating a three dimensional model of an object, the method comprising the steps of:
-
placing the object using a placing unit such that the object is in the field of view of an image capturing unit capturing an image of the object, wherein the image capturing unit and an illumination unit are connectedly moveable relative to the placed object;
taking a plurality of silhouette images of the object using the image capturing unit, with the illumination unit providing illumination for the image capturing device to take the silhouette images of the object; and
using the plurality of images to generate a three dimensional model of the object. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
