Patents by Inventor David M. McClatchy, III

David M. McClatchy, III has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230363647
    Abstract: A method for determining sub-diffuse scattering parameters of a material includes illuminating the material with structured light and imaging remission by the material of the structured light. The method further includes determining, from captured remission images, sub-diffuse scattering parameters of the material. A structured-light imaging system for determining sub-diffuse scattering parameters of a material includes a structured-light illuminator, for illuminating the material with structured light of periodic spatial structure, and a camera for capturing images of the remission of the structured light by the material. The structured-light imaging system further includes an analysis module for processing the images to quantitatively determine the sub-diffuse scattering parameters. A software product includes machine-readable instructions for analyzing images of remission of structured light by a material to determine sub-diffuse scattering parameters of the material.

  • Patent number: 10485425
    Abstract: A structured-light imaging system includes a structured light projector for illuminating a surface and an electronic camera configured to image the surface. An image processor receives the images and has structured light scatteroscopy (SLS) firmware with machine readable instructions that illuminate the surface with structured light having a spatial frequency of at least 0.5 mm?1, and process the images to determine a map of scattering parameters at the surface independent of absorption properties. In an embodiment, the system also has cameras configured to obtain a stereo pair of images of the surface, the image processor having 3D firmware for extracting a three dimensional model of the surface from the stereo pair of images and compensating the map for non-flat surfaces.
