  • Patent number: 6438263
    Abstract: A system for reconstructing the surface geometry of an object includes a three-view optic head, a mechanical manipulator, a local 3D surface geometry reconstruction unit and a surface geometry stitching unit. The three-view optic head is operative to generate at least three views of at least a portion of the object. The mechanical manipulator is operative to vary the relative orientation of the object and the optic head, at a precision less than the a predetermined degree of precision, from a first relative orientation in which a first portion of the object is visible to at least one second relative orientation in which a second portion of the object, which overlaps the first portion, is visible. The local 3D surface geometry reconstruction unit is operative to generate local reconstructions of the surface geometries of the first and second portions of the object, based on at least two of three views of the first and second portions generated by the optic head.

  • Patent number: 6201541
    Abstract: A system is disclosed for stitching a plurality of reconstructions of three-dimensional surface features of at least one object in a scene to relate the reconstructions to a common coordinate system. Each reconstruction is generated from a plurality of two-dimensional images of the scene, and each reconstruction is defined relative to a respective one of a plurality of reconstruction coordinate systems defined relative to one of the images in the scene. The system generates, from at least some of the images, values for translational and rotational components relating a respective reconstruction coordinate system to the common coordinate system. Thereafter, the system uses the values of the translational and rotational components to convert coordinates of the surface features in the respective reconstruction coordinate systems to the common coordinate system.
