  • Wear measurement system using a computer model
    Patent number: 9880075
    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.
    Type: Grant
    Filed: February 11, 2016
    Date of Patent: January 30, 2018
    Assignee: Caterpillar Inc.
    Inventors: Nolan S. Finch, Yue Wang, Kook In Han, Timothy J. Bennett, Daniel A. Smyth
