US Patent:

20110068173, Mar 24, 2011

Filed:

Sep 17, 2010

Appl. No.:

12/885155

Inventors:

Jeffrey Roger Powers - Boulder CO, US
Vikas Muppiddi Reddy - Boulder CA, US

Assignee:

eBay Inc. - San Jose CA

International Classification:

G06K 7/14

US Classification:

23546206, 23546208, 23546225

Abstract:

In a system and method of recognizing a barcode from a stream of video frames, a processor-implemented camera module receives a stream of video frames, with at least one video frame including a barcode. A processor-implemented barcode blur estimate module estimates an amount of defocus blur in a video frame. The processor-implemented barcode blur estimate module further estimates an identity of the barcode. A processor-implemented barcode localization module identifies a region of the video frame containing the barcode. A processor-implemented barcode geometric modeler module generates a geometric model of the barcode that includes an identified barcode deformity. A processor-implemented barcode decoder module decodes the barcode from the video frame using the estimated amount of defocus blur, the estimated identity of the barcode, and the geometric model of the barcode.

International Classification:

G06K 7/14

US Classification:

23546225

Abstract:

In a system and method of estimating and classifying a barcode using heuristic and statistical measures, a classification determination is generated for each of a plurality of estimated barcode digits that correspond to a decoded barcode estimation. The classification determination is selected from one of a first classification determination and a second classification determination. The first classification determinations among a plurality of estimation determinations are aggregated. The aggregated first classification determinations are compared to a first predetermined threshold to determine a validity of the decoded barcode estimation.

International Classification:

G06T 19/00
G06F 30/13
G06T 17/20

Abstract:

A system for generating three-dimensional models of a physical environment such as a room. In some cases, the system may utilize a two-dimensional floor, room, or house plan to generate, close and/or orthogonalize wall segments. The system may then generate a three-dimensional model by projecting the wall segments into a three-dimensional space and inserting objects.

International Classification:

G06F 3/04815
G06F 3/04845
G06F 3/0482

Abstract:

A system configured to generate a three-dimensional scene of a physical environment. In some cases, the system may present the three-dimensional scene such that the user is able to view the model in various different types. The system may also allow the user to capture various measurements associated with the scanned physical environment by selecting different portions of the scene.
