US Patent:

20170234775, Aug 17, 2017
Filed:

Feb 11, 2016
Appl. No.:

15/041523
Inventors:

- Peoria IL, US
Yue WANG - Anhui, CN
Kook In HAN - Savoy IL, US
Timothy J. BENNETT - Bloomington IL, US
Daniel A. SMYTH - Metamora IL, US
Assignee:

Caterpillar Inc. - Peoria IL
International Classification:

G01M 17/03
G01N 21/88
G06F 17/50
Abstract:

A wear measurement system for a component is disclosed. The wear measurement system may include an imaging device configured to obtain a plurality of two-dimensional images of the component. The wear measurement system may also include a controller. The controller may be configured to generate a three-dimensional point cloud representing the component based on the two-dimensional images. The controller may also be configured to overlay a computer model of the component on the three-dimensional point cloud. Further, the controller may be configured to project the computer model on the two-dimensional images. The controller may also be configured to select at least two reference points appearing in each of a subset of images selected from the two-dimensional images. The controller may be configured to determine locations of the two reference points in the three-dimensional point cloud, determine an image distance between the locations, and determine an amount of wear based on the image distance.
