  • Publication number: 20250104340
    Abstract: Systems and methods for performing multispectral quality control inspection scans of a physical object are disclosed. A handheld scanning device separately illuminates a physical object with a plurality of light sources and captures corresponding images of the physical object. The physical object may comprise an article of manufacture. The light sources, such as laser diodes and light-emitting diodes, use wavelengths selected for investigative and three-dimensional modeling efficacy, which may be based on translucence and fluorescence characteristics in objects being observed. The images, and a three-dimensional model derived therefrom potentially substantially immediately thereafter, form an investigative rendering that may be stored, presented, and analyzed to identify discrepancies to be further examined. Additional images, such as x-ray images obtained from other instruments, may be added to the rendering, to help more completely determine if the physical object meets particular specifications.

  • Publication number: 20250099211
    Abstract: Systems and methods for performing multispectral intra-oral and other diagnostic scans of a physical object are disclosed. A handheld scanning device separately illuminates the physical object with a plurality of light sources and captures corresponding images of the physical object, which may comprise a patient's tooth, intra-oral tissue, or skin. The light sources, such as laser diodes and light-emitting diodes, use wavelengths selected for diagnostic and three-dimensional modeling efficacy, which may be based on translucence and fluorescence characteristics in objects being observed. The images, and a three-dimensional model derived therefrom potentially substantially immediately thereafter, form a diagnostic rendering that may be stored, presented, and analyzed to design and evaluate medical treatment plans.

  • Patent number: 11925435
    Abstract: An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device provides for more efficient transmission and capture of images. It integrates OCT scanning with RGB-based scanning. In operation, the device is used for recording topological characteristics of teeth, dental impressions, or stone models by digital methods and for use in CAD/CAM of dental restorative prosthetic devices. To that end, the RGB-based scan obtains surface data (e.g., a margin), while the OCT scan penetrates the surface. The two scanners operate from within the same physical housing and preferably at the same time such that only one scanning pass (to obtain all necessary data) is required. The 3D data obtained from the OCT scan is registered with the 3D data obtained from the RGB-based scan by virtue of being captured using a common return path.

  • Patent number: 8532355
    Abstract: Methods, systems, and devices for generating textured 3D models are provided. The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. In some instances, the textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time on a display. The present disclosure also describes methods, systems, and devices for selecting the images and, in particular, the portions of the selected images to map to defined portions of the 3D model. In addition, the present disclosure describes how to adjust the images themselves to remove the effects of directional lighting. Some aspects of the present disclosure are particularly useful in the context of a 3D modeling of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations.
