First Claim
Patent Images
1. A structured light imaging (SLI) system, comprising:
- a projection system that is operable to project a single SLI pattern into an imaging area;
an image sensor system that is operable to capture an image of a 3D object moving through the imaging area in each frame period, wherein the image sensor system outputs a subset of camera pixels in the frame period to generate subwindow images; and
a processing module that is operable to create a 3D surface map of the 3D object based on the subwindow images.

Abstract
A structured light imaging (SLI) system includes a projection system, image sensor system and processing module. The projection system is operable to project a single SLI pattern into an imaging area. The image sensor system is operable to capture images of a 3D object moving through the imaging area. The image sensor system outputs a subset of camera pixels corresponding to a subwindow of a camera frame to generate subwindow images. The processing module is operable to create a 3D surface map of the 3D object based on the subwindow images.

7. An SLI system for imaging a fingerprint, comprising:
-
a projection system that is operable to project a single SLI pattern onto a fingerprint in an imaging area; an image sensor system that is operable to capture a series of images of the fingerprint moving through the imaging area, wherein the image sensor system generates subwindow images of the fingerprint by outputting a subset of camera pixels in a frame period; and a processing module that is operable to create a 3D surface map of the fingerprint based on the subwindow images. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
