Methods And Apparatus For Constructing A 3D Model Of A Scene From Calibrated Images Of The Scene

View page
US Patent:
6373487, Apr 16, 2002
Filed:
Sep 17, 1999
Appl. No.:
09/398489
Inventors:
W. Bruce Culbertson - Palo Alto CA
Thomas Malzbender - Palo Alto CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G06T 1700
US Classification:
345424, 382132
Abstract:
Methods and apparatus are provided for volumemetric scene reconstruction. Given a set of images of the scene taken from arbitrary but known locations, a 3D model of the scene is reconstructed. Voxels are used to model the scene and exploit the fact that surface points in the scene, and the voxels that represent them, project to consistent colors in the input images. Input cameras may be placed at arbitrary locations in and around the scene. When checking the color consistency of a voxel, the entire set of images from which the voxel is visible is used. A GVC algorithm utilizes item buffers which contain, for each pixel in each image, the ID of the closest voxel that projects onto to the pixel. A GVC-LDI algorithm uses layered depth images which store at each pixel location a list of all the surface voxels that project onto the pixel, sorted according to the distance of the voxel from the images camera.

Apparatus For And Of Rendering 3D Objects With Parametric Texture Maps

View page
US Patent:
6515674, Feb 4, 2003
Filed:
Mar 17, 2000
Appl. No.:
09/528700
Inventors:
Daniel George Gelb - Los Altos CA
Hans Juergen Wolters - Mountain View CA
Thomas Malzbender - Palo Alto CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G06T 1550
US Classification:
345582, 345584, 345586, 345426
Abstract:
A graphics system that employs parametric texture maps. The graphics system renders surface features of a 3D object in a manner that is direction dependent but without the time consuming and expensive calculations involved in the evaluation of lighting equations on a per pixel basis. A parametric texture map holds a set of parameters that define a surface structure in a manner in which the appearance of the surface structure varies in response to a direction vector. The direction vector may be any user-defined vector including a light source vector or a half-angle vector. The parameters are those of a predetermined equation, the evaluation of which does not involve vector calculations. The equation may take any form including a polynomial equation or a non-polynomial equation. The graphic system renders a polygon with the surface structure using the equation.

Apparatus For And Method Of Enhancing Shape Perception With Parametric Texture Maps

US Patent:
6654013, Nov 25, 2003
Filed:
Mar 17, 2000
Appl. No.:
09/527872
Inventors:
Thomas Malzbender - Palo Alto CA
Daniel George Gelb - Los Altos CA
Hans Juergen Wolters - Mountain View CA
Assignee:
Hewlett-Packard Development Company, LP. - Houston TX
International Classification:
G06T 1560
US Classification:
345426, 345584
Abstract:
A graphics system that enhances shape perception. The presently preferred embodiment of the system utilizes the mathematical machinery of parametric texture maps. In general, parametric texture maps allow the graphics system to render surface features of a 3D object in a manner that is direction dependent but without the time consuming and expensive calculations involved in the evaluation of lighting equations on a per pixel basis. A parametric texture map holds a set of parameters that define a surface structure in a manner in which the appearance of the surface structure varies in response to a direction vector. The direction vector may be any user-defined vector including a light source vector or a half-angle vector. The parameters are those of a predetermined equation, the evaluation of which does not involve vector calculations. The equation may take any form including a polynomial equation or a non-polynomial equation.

Method And Apparatus For Varying Focus In A Scene

View page
US Patent:
6741251, May 25, 2004
Filed:
Aug 16, 2001
Appl. No.:
09/932691
Inventors:
Thomas Malzbender - Palo Alto CA
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G06T 500
US Classification:
345428, 345426, 345582, 345589
Abstract:
A method of varying focus in a scene. Specifically, one embodiment of the present invention discloses a method for modeling a scene using a parametric texture map (PTM) under varying focus conditions of one or more dimensions: e. g. , focus depth and depth of field. A dataset of photographs is obtained under separate focus conditions. Approximation of the dataset creates an associated PTM representation that is capable of generating scenes of the photographic scene under varying focus conditions anywhere within the range of focus conditions specified by the initial data set. In addition, extrapolation yields results outside the range of focus conditions.

Method And System For Real-Time Video Communication Within A Virtual Environment

US Patent:
6853398, Feb 8, 2005
Filed:
Jun 21, 2002
Appl. No.:
10/176494
Inventors:
Thomas Malzbender - Palo Alto CA, US
W. Bruce Culbertson - Palo Alto CA, US
H. Harlyn Baker - Los Altos CA, US
Michael E. Goss - Burlingame CA, US
Daniel G. Gelb - Los Altos CA, US

Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H04N007/14
US Classification:
348 1409, 348 1408, 348 1416
Abstract:
A method for real-time video communication. Specifically, one embodiment of the present invention discloses a method of video conferencing that captures a plurality of real-time video streams of a local participant from a plurality of sample viewpoints. From the plurality of video streams, a new view synthesis technique can be applied to generate a video image stream in real-time of the local participant rendered from a second location of a second participant with respect to a first location of the local participant in a coordinate space of a virtual environment. A change in either of the locations leads to the modifying of the video image stream, thereby enabling real-time video communication from the local participant to the second participant.

US Patent:
6914600, Jul 5, 2005
Filed:
Jun 26, 2001
Appl. No.:
09/893146
Inventors:
Thomas Malzbender - Palo Alto CA, US
Gregory Gilbran Slabaugh - Atlanta GA, US
William Bruce Culbertson - Palo Alto CA, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G06T017/00
US Classification:
345424
Abstract:
A method of generating a three-dimensional model of a scene from a plurality of photographs of the scene. The method includes voxels in an interior region and an exterior region of the scene in question and then examines the voxels to determine if they are empty or part of the objects in the scene. The interior region is divided into a plurality of interior voxels, that are preferably of the same size. The exterior region surrounds the interior space and is divided into exterior voxels having different sizes. The size of the exterior voxels increases as a function of the distance between the voxel and the interior region. The voxels that are furthest from the interior region are preferably infinite in size.

10/690882
Inventors:
Charles B Chapman - San Diego CA, US
Ryan Wilshusen - San Diego CA, US
Daniel George Gelb - Los Altos CA, US
Thomas Malzbender - Palo Alto CA, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

F16M011/00
US Classification:
396 4, 396182, 396428, 362 11, 2481631
Abstract:
A support apparatus for a camera and strobe lights includes a mounting plate for holding the camera substantially normal to and at a fixed distance from the photograph area, a set of legs attached to one or more portions of the apparatus providing support and positions for mounting and a set of strobe lights affixed to the legs at known positions relative to the focal plane of the camera and directed towards the photograph area to facilitate acquisition of multiple photographic images for use in one or image processing operations. The support apparatus can be automated through the use of one or more mobile strobe lights slidably coupled to each leg, capable of self-propelled linear motion along the axis of the leg and providing indication of its position along the leg to facilitate acquisition of multiple photographic images and position data for the image processing operations.
