  • Patent number: 12165387
    Abstract: A method of inspecting a composite structure formed of plies of tows is provided. The method involves receiving an image of an upper ply overlapping lower plies, the upper ply tow ends defining a boundary between plies, and applying extracted sub-images to a trained machine learning model to detect the upper or lower ply. Probability maps are produced in which pixels of the sub-images are associated with probabilities the pixels belong to an object class for the upper or lower ply. The method may also involve transforming the probability maps into reconstructed sub-images, stitching together a composite image, and applying the composite image to a feature detector to detect locations of tow ends of the upper ply. The method may also involve comparing the locations to as-designed locations of the tow ends, inspecting the composite structure, and indicating a result of the comparison.

  • Publication number: 20210232810
    Abstract: In some embodiments, a system is provided that comprises a computing system including at least one computing device and a camera communicatively coupled to the computing system via a network. The computing system is configured to generate a set of features based on three-dimensional joint location data representing postures of a subject over a plurality of time steps depicted in video data captured by the camera; provide the set of features to a first machine learning model trained to identify a start time step, an end time step, and an action identity for each action; provide the set of features to a second machine learning model trained to determine a postural assessment score for each time step; and determine an action score for each action based on the start time steps, the end time steps, the action identities, and the postural assessment scores for each time step.
