Three-Dimensional Integral-Imaging Display From Calibrated and Depth-Hole Filtered Kinect Information

subject

description

We exploit the Kinect capacity of picking up a dense depth map, to display static three-dimensional (3D) images with full parallax. This is done by using the IR and RGB camera of the Kinect. From the depth map and RGB information, we are able to obtain an integral image after projecting the information through a virtual pinhole array. The integral image is displayed on our integral-imaging monitor, which provides the observer with horizontal and vertical perspectives of big 3D scenes. But, due to the Kinect depth-acquisition procedure, many depthless regions appear in the captured depth map. These holes spread to the generated integral image, reducing its quality. To solve this drawback we propose here, both, an optimized camera calibration technique, and the use of an improved hole-filtering algorithm. To verify our method, we performed an experiment where we generated and displayed the integral image of a room size 3D scene.
