Abstract
Official abstract text for this publication.
Generating computer models of 3D objects is described. In one example, depth images of an object captured by a substantially static depth camera are used to generate the model, which is stored in a memory device in a three-dimensional volume. Portions of the depth image determined to relate to the background are removed to leave a foreground depth image. The position and orientation of the object in the foreground depth image is tracked by comparison to a preceding depth image, and the foreground depth image is integrated into the volume by using the position and orientation to determine where to add data derived from the foreground depth image into the volume. In examples, the object is hand-rotated by a user before the depth camera. Hands that occlude the object are integrated out of the model as they do not move in sync with the object due to re-gripping.
First claim
Opening claim text (preview).
The invention claimed is: 1. A computer-implemented method of generating a 3D model of an object, comprising: organizing, in a memory device, storage of data associated with a three-dimensional volume associated with the model, the volume comprising a plurality of voxels; receiving a depth image from a substantially static depth camera, the depth image comprising a depth value at each image element relating to a distance from the depth camera to a scene comprising the object;…
