Apparatus and method for object shape detection
First Claim
1. An apparatus for generating a silhouette of an object for use in generating a 3-dimensional model of the said object, the apparatus comprising a light projecting device, an image capturing device and an arrangement for mounting the said object between the light projecting device and the image capturing device, wherein said light projecting device includes a two-dimensional arrangement of light projecting elements, each light projecting element having a light source associated therewith, and wherein the light projecting elements are arranged to direct light towards said image capturing device, whereby a silhouette of said object is generated at said image capturing device.

Abstract
A light projecting device including a two-dimensional array of light projecting elements is used to project light towards an image capturing device. An arrangement for mounting an object to be modelled is provided between the light projecting device and the image capturing device. The light projecting elements are arranged to direct light towards said image capturing device, whereby a silhouette of the object is generated at the image capturing device. The silhouette is used for generating a three-dimensional model of the object.
