    Abstract: A 3D image apparatus using a single optical channel for capturing multiple view-angle images of an object for use in generating a 3D image or model of the object. The apparatus includes within the optical train an active optical component, an aperture plate having an aperture, a lens for focusing light from the aperture, and an image sensor. The active optical component has a changeable shape or position for providing first and second optical wavefronts through the aperture and focused by the lens onto the image sensor from first and second view angles of the object. The second optical wavefront is shifted by the active optical component on the image sensor with respect to the first optical wavefront in order to provide multiple view-angle images along the single optical channel, which can be used to generate a 3D model or image of the object.

    Abstract: Apparatus for powder-free intra-oral 3D imaging by using a projected texture pattern. A projector projects a random texture pattern of light to teeth to be imaged, and a digital image sensor receives the projected texture pattern from the teeth. The reflected pattern of light reflects and scatters from the teeth. The texture pattern can be a grid having clusters of bright and dark blocks in a pseudo-random arrangement and can provide for powder-free intra-oral 3D imaging by using the pattern to optically simulate powder applied to the teeth. Polarizers can be used in the optical path to transmit the directly reflected light to the image sensor and suppress or discard some of the unwanted scattered light.

    Abstract: Three-dimensional test objects provide for assessment of a 3D scanner over a range of scales, frequencies, and/or depths. The test objects may include a substrate having a substantially planar top surface and a plurality of surface features. In some examples, the surface features include a plurality of wedges projecting above the plane of the top surface and extending radially outward from an origin to form a three dimensional star pattern. The shape of the surface features may be periodic or non-periodic. In other examples, the depth of the surface features is decoupled from their lateral frequency.

    Abstract: A non-parametric computer implemented system and method for creating a two dimensional interpretation of a three dimensional biometric representation. The method comprises: obtaining with a camera a three dimensional (3D) representation of a biological feature; determining a region of interest in the 3D representation; selecting an invariant property for the 3D region of interest; identifying a plurality of minutiae in the 3D representation; mapping a nodal mesh to the plurality of minutiae; projecting the nodal mesh of the 3D representation onto a 2D plane; and mapping the plurality of minutiae onto the 2D representation of the nodal mesh. The 2D representation of the plurality of minutiae has a property corresponding to the invariant property in the 3D representation; and the value of the corresponding property in the 2D projection matches the invariant property in the 3D representation.
