    Abstract: An apparatus includes a memory configured to store multiple sets of image data. Each of the sets corresponds to a respective portion of a surface of an object and a respective portion of a structured light pattern projected onto the surface. The apparatus includes a processor configured to perform structured light reconstruction of the sets, including matching a first group of image pixels that correspond to a projected pixel of the structured light pattern in a first set of image data with a second group of image pixels that correspond to the projected pixel in a second set of image data. The processor is configured to perform stereo reconstruction of the sets, including matching one or more features detected within the first group of image pixels with one or more features detected within the second group of image pixels, to generate three-dimensional point data of the surface.

    Abstract: A method includes generating, based on first surface data that includes three-dimensional (3D) point positions corresponding to a first portion of a surface of an object, first hole data that indicates first positions of holes in the first portion of the surface. The method includes generating, based on second surface data corresponding to a second portion of the surface of the object, second hole data that indicates second positions of the holes in the second portion of the surface. The method also includes matching the first positions to the second positions to perform an alignment with respect to the first surface data and the second surface data.

    Abstract: Provided are methods and systems for inspecting surfaces of various components, such as evaluating height deviations on these surfaces. A method involves aggregating inspection data from multiple line scanners into a combined data set. This combined data set represents a portion of the surface that is larger than the field of measurement any one of the scanners. Furthermore, each pair of adjacent scanners operate at different periods of time to avoid interference. Because operating periods are offset, surface portions scanned by the pair of adjacent scanners can overlap without interference. This overlap of the scanned portions ensures that the entire surface is analyzed. The position of scanners relative to the inspection surface may be changed in between the scans and, in some embodiments, even during the scan. This approach allows precise scanning of large surfaces.

    Abstract: Methods of performing a rotational and translational calibrations of a print control system of an inkjet printer system having an inkjet printhead assembly with one or more inkjet printheads are disclosed. Rotational calibration is performed by printing a first rotational calibration pattern from a first standoff distance and a second rotational calibration pattern from a second standoff distance on a first calibration object. The print control system is calibrated until the rotational calibration patterns are within a direction difference tolerance of each other. Translational calibration is performed by printing a first translation calibration pattern on a second calibration object, rotating the inkjet printhead assembly 180°, and printing a second translational calibration pattern on the second calibration object. The print control system is calibrated until the translational calibration patterns are within a direction difference tolerance of each other.

    Abstract: A method of developing an automatic control plan for printing on a contoured surface is disclosed. The method includes scanning a contoured surface with a surface scanning device to produce a contoured data set, and creating a multi-dimensional model, with a computing device, of the contoured surface based on the contoured surface data set. Additionally, the method includes inputting a multi-dimensional model of a printing array and an image to be printed onto the contoured surface, into the computing device. The method further includes simulating, on the computing device, a plurality of movements performed by the printing array and a printing by the printing array to apply the image on the contoured surface. Additionally, the method includes, compiling, on the computing device, the automatic control plan which is programmed to execute the plurality of movements of the printing array to apply the image on the contoured surface.
