  • Patent number: 10706570
    Abstract: A system and method for acquiring the three-dimensional shape of an object. At least one camera captures a scene in which a projected pattern is moved across an object and reference surface. The movement of said pattern need not be perfectly uniform, because differences in the movement at each step are detected and compensated. This compensation reduces the required hardware complexity and cost.

    Abstract: In the measuring device and measuring method, confocal measuring principle is utilized. A certain component of an optical measurement signal is, from the point of view of both illumination and imaging, in focus only at one point on the virtual measuring surface. In the measuring device, the surface to be measured always hits a common focus point of the illumination and imaging, whereby a reflection is generated. The reflected optical signal is directed to a detector belonging to the imaging unit, where one picture element of the detector corresponds to a certain focus point, respectively. The optical efficiency received by each picture element is indicated. The light reflecting from the intersection of the virtual measuring surface and the surface of the object produces an intensity maximum for the detector. This maximum point is indicated and converted in the imaging unit (13) into the height of the surface of the object.

  • Patent number: 9405365
    Abstract: A system is provided for identifying reference locations within the environment of a device wearer. The system includes a scene camera mounted on eyewear or headwear coupled to a processing unit. The system may recognize objects with known geometries that occur naturally within the wearer's environment or objects that have been intentionally placed at known locations within the wearer's environment. One or more light sources may be mounted on the headwear that illuminate reflective surfaces at selected times and wavelengths to help identify scene reference locations and glints projected from known locations onto the surface of the eye. The processing unit may control light sources to adjust illumination levels in order to help identify reference locations within the environment and corresponding glints on the surface of the eye. Objects may be identified substantially continuously within video images from scene cameras to provide a continuous data stream of reference locations.

  • Patent number: 8993914
    Abstract: A high-speed, high-resolution, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspected parts are provided. The method includes consecutively transferring the parts so that the parts move along a path which extends from a supply of parts and through an imaging station. A triangulation-based sensor head is supported at the imaging station. The sensor head is configured to generate focused lines of radiation and to sense corresponding reflected lines of radiation. The focused lines are delivered onto an end surface of each part to obtain a corresponding array of reflected lines of radiation. The sensor head senses the array of reflected lines to obtain a corresponding set of 2-D profile signals. The set of profile signals represent a 3-D view of the end surface. The set of 2-D profile signals of each part is processed to identify parts having an unacceptable defect.
