The direct measurement generates a first point cloud and a plurality of second point clouds. The first point cloud corresponds to the exterior surface and includes a plurality of first data points, each data point having an X-axis coordinate, a Y-axis coordinate, and a Z-axis coordinate. Each second point cloud corresponds to one of the plurality of passive strain indicators and includes a plurality of second data points, each data point having an X-axis coordinate, a Y-axis coordinate, and a Z-axis coordinate. A second data point density of each second point cloud is greater than a first data point density of each first point cloud.

  • Publication number: 20180156694
    Abstract: This disclosure provides systems, components, and methods for visual creep inspection of rotating components, such as those in a gas turbine. A component is provided with an external surface and an axis of rotation. The external surface has a circumference and a plurality of three dimensional reference marks forming a reference pattern along the circumference. An optical data capture device generates a data signal based on the plurality of three dimensional reference marks. A data analysis system processes the data signal to calculate a deviation in spacing of the reference pattern along the circumference and determines a strain or creep measurement.
