Patent number: 7728848Abstract: Improvement of the performance, usability, and functionality of software for editing three dimensional computer models and textures is described. Editing operations are performed on the model in an ordered list to reduce the amount of memory required to maintain previous versions, and certain editing operations are precalculated to reduce the amount of real time calculation required. Improvements to usability and functionality are provided by more precisely selecting portions of a model for editing, allowing textures to be moved more easily on the model, and allowing better blending of the appearance of adjacent textures.Type: GrantFiled: March 28, 2001Date of Patent: June 1, 2010Assignee: DG FastChannel, Inc.Inventors: Michael Petrov, Alexander Migdal, Alexei Lebedev, Veronika Shelyekhova, Leonid Polonskiy, Vadim Abadjev

Patent number: 7474803Abstract: System and method for constructing a 3D model of an object based on a series of silhouette and texture map images. In the exemplary embodiment an object is placed on a rotating turntable and a camera, which is stationary, captures images of the object as it rotates on the turntable. In one pass, the system captures a number of photographic images that will be processed into image silhouettes. In a second pass, the system gathers texture data. After a calibration procedure (used to determine the camera's focal length and the turntable's axis of rotation), a silhouette processing module determines a set of two-dimensional polygon shapes (silhouette contour polygons) that describe the contours of the object. The system uses the silhouette contour polygons to create a 3D polygonal mesh model of the object. The system determines the shape of the 3D model analytically by finding the areas of intersection between the edges of the model faces and the edges of the silhouette contour polygons.Type: GrantFiled: May 30, 2006Date of Patent: January 6, 2009Assignee: Enliven Marketing Technologies CorporationInventors: Michael Petrov, Alexander Migdal, Alexei Lebedev, Veronika Shelyekhova, Leonid Polonskiy, Vadim Abadjev

Patent number: 7453456Abstract: Systems and methods for identifying the contour of an object that is depicted in an image. An object is placed on a rotating turntable and a camera, which is stationary, captures images of the object as it rotates on the turntable. In one pass, the system captures a number of photographic images that will be processed into image silhouettes. After a calibration procedure (used to determine the camera's focal length and the turntable's axis of rotation), a silhouette processing module determines a set of two-dimensional polygon shapes (silhouette contour polygons) that describe the contours of the object by comparing light intensity values in the images of the object with light intensity values from an image of the background without the object.Type: GrantFiled: May 30, 2006Date of Patent: November 18, 2008Assignee: Enliven Marketing Technologies CorporationInventors: Michael Petrov, Alexander Migdal, Alexei Lebedev, Veronika Shelyekhova, Leonid Polonskiy, Vadim Abadjev

Patent number: 6549288Abstract: The present invention provides a system for illuminating an object with a special kind of structured light pattern, recording the shape of the reflected points of light by means of a camera, and, by a triangulation technique that does not depend on the fixed direction of the light source relative to the camera, reconstructing the 3D shape of the object through a computer using the data points collected from the reflection of the structured light pattern. The scanning system is portable and does not require data processing contemporaneous with the data collection. The portable system stores in the storage media several images of the objects with different illumination patterns. The data is subsequently processed, by a computer system which applies data processing routines, i.e., the model building algorithms which provide 3D surface generation.Type: GrantFiled: May 14, 1999Date of Patent: April 15, 2003Assignee: Viewpoint Corp.Inventors: Alexander Migdal, Michael Petrov, Alexei Lebedev, Veronika Shelyekhova, Vadim Abadjev, Vladimir Bernstein, Andrei Afanassenkov
