    Abstract: Systems and methods that provide a framework for location tracking of a movable target component or device (e.g., an automated device or a hand-operated device) to accurately cover an area of interest along a specified path or in a specified region. Grid patterns are projected onto a surface of a workpiece or a part. The projected grid lines may be straight or curved. Straight grid lines can be parallel or intersecting. The grid pattern may include a path to be followed. The lines of the projected grid pattern are detected by a grid detection sensor which is mounted onboard the movable target component or device. Information from the grid detection sensor is fed to a location mapping program. The systems and methods also enable navigation for use in automated and autonomous manufacturing and maintenance operations, as well as other tracking-based applications.

    Abstract: Systems and methods for inspecting a surface are disclosed. A source, detector, a base, a controller, and a processing device are used to collect image data related to the surface and information relating to the location of the image data on the surface. The image data and information relating to location are correlated and stored in a processing device to create a map of surface condition.

    Abstract: Systems and methods for mapping a damaged region on an object. An exemplary system captures an image of the damaged region with a camera, selects target points around a boundary of the damaged region on the image, and determines 2D image coordinates for the target points on the image. The system further determines angles for aiming a laser ranging device at each of the target points based on the image coordinates, and measures a distance to each of the target points with the laser ranging device based on the aiming angles. The system then calculates 3D coordinates for each of the target points in the coordinate system of the object based on the distance measurement and the 2D image coordinates for each of the target points.

    Abstract: A system for stand-off inspection comprising local positioning system hardware and a nondestructive evaluation instrument supported by a pan-tilt mechanism. The system further comprises a computer system that is programmed to perform the following operations: (a) directing the local positioning system hardware toward an area of a surface on a target object by control of the pan-tilt mechanism; (b) activating the local positioning system hardware to acquire an image; (c) processing the image to determine whether an anomaly is present in the area; (d) if an anomaly is present, determining coordinates of a position of the anomaly in a coordinate system of the target object; and (e) directing the nondestructive evaluation instrument toward a position corresponding to the coordinates. Optionally, the computer system is further programmed to measure one or more characteristics of the anomaly.

    Abstract: Systems and methods for automated non-destructive inspection scanning of the top and bottom aerodynamic surfaces or skins of an integrally stiffened wing box (e.g., a horizontal stabilizer) using surface crawling vehicles. Each system uses dynamically controlled magnetic coupling to couple an external drive tractor to a pair of passive trailers disposed in the interior of the wing box on opposite sides of a spar. The external drive tractor is also coupled to an external NDI scanner, which the tractor pushes or pulls across the surface skin being inspected. The systems allow scanning of both surface skins without turning the wing box over. Each system is modular and can be transported to and easily set up in a building or factory.
