  • Patent number: 7768656
    Abstract: A system and method are provided for the 3D measurement of the shape of material objects using non-contact structured light triangulation. The system includes a light projector for projecting a structured light pattern onto the surface of any object and a camera for capturing an image of the structured light pattern acting on the surface of the object. The system further includes computing device for determining the 3D measurement of the surface shape of the illuminated object through a triangulation algorithm employed based on a calculated correspondence between the projected structured light and the captured image. The structured light includes coded elements that lie within planes passing through vertices of the central projection areas of both the projector and the camera also that pass through the space of the object being measured.

  • Publication number: 20090067706
    Abstract: A system and method are provided for the multiframe surface measurement of the shape of material objects. The system and method include capturing a plurality of images of portions of the surface of the object being measured and merging the captured images together in a common reference system. The shape and/or texture of a complex-shaped object can be measured using a 3D scanner by capturing multiple images from different perspectives and subsequently merging the images in a common coordinate system to align the merged images together. Alignment is achieved by capturing images of both a portion of the surface of the object and also of a reference object having known characteristics (e.g., shape and/or texture). This allows the position and orientation of the object scanner to be determined in the coordinate system of the reference object.
