  • Scanning arrangement and method
    Patent number: 6128086
    Abstract: A scanning arrangement comprising means (40) for projecting a two-dimensional optical pattern on a surface (35) of a scanned object and a two-dimensional photodetector (34') is mounted within a hand-held scanning device and outputs scan files of 3D coordinate data of overlapping surface portions of the object. The surface portions defined by these scan files are registered by appropriate rotations and translations in a computer, which are determined either from the outputs of a gyroscope (51) and an accelerometer (50) or by mathematical processing of the surface portions e.g. involving detection and location of common features.
    Type: Grant
    Filed: May 10, 1999
    Date of Patent: October 3, 2000
    Assignee: Tricorder Technology plc
