System and method for verification of three-dimensional (3d) object

Abstract

A system and method of determining whether an object captured in a series of images is a three dimensional object or an image of an object by comparing image data of the object captured in the images at various angles relative to the object, to image data of one or more reference images of an actual object. The image data derived from the captured images may vary with the different angles at which such images were captured and such variances may be compared to the reference images, whereas image data of an image of an object will not comparably vary

We claim: 
     
         1 . A method of determining that an object depicted in camera images is a three dimensional object, the method comprising:
 receiving image data derived from images captured by a camera, the image data comprising at least first image data derived from a first image of an object and second image data derived from a second image of an object;   comparing said first image data and said second image data to reference data, wherein said reference data is derived from multiple images of a reference object and each of said multiple images corresponds to a different value of at least one image parameter; and   determining that the first and second images depict a three dimensional object if the result of the comparison satisfies one or more predetermined criteria.
