1. A computer implemented method comprising:
- acquiring a three-dimensional (3D) range image containing one or more 3D landmarks;
rendering the 3D range image into a rendered visible image containing intensity patterns related to the one or more 3D landmarks, wherein rendering the 3D range image includes generating a two-dimensional synthetic image from a scene file, and wherein the scene file includes objects in a defined language as a description of a virtual scene; and
localizing at least one of the one or more 3D landmarks in the rendered visible image to provide at least one localized 3D landmark, wherein the at least one localized 3D landmark is compared with at least one 3D landmark in a reference 3D image to provide a general identification or a biometric identification.

Abstract
A computer implemented method comprising acquiring a three-dimensional (3D) range image containing one or more 3D landmarks; rendering the 3D range image into a rendered visible image containing intensity patterns related to the one or more 3D landmarks; and localizing at least one of the one or more 3D landmarks in the rendered visible image to provide at least one localized 3D landmark. is provided. Such methods, and related systems, and devices, are useful in biometric identification applications.

13. A system comprising:
-
a three-dimensional (3D) range image acquiring device associated with a 3D range image containing one or more 3D landmarks; a rendering device configured for rendering the 3D range image into a rendered visible image containing intensity patterns related to one or more 3D landmarks, wherein rendering the 3D range image includes generating a two-dimensional synthetic image from a scene file, and wherein the scene file includes objects in a defined language as a description of a virtual scene; and a landmark localization device in communication with the rendering device, the landmark localization device configured to localize at least one of the one or more 3D landmarks in the rendered visible image to provide at least one localized 3D landmark, wherein the at least one localized 3D landmark is compared with at least one 3D landmark in a reference 3D image to provide a general identification or a biometric identification. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
