A system and method for imaging a foot and/or producing a shoe for a foot. The system includes a display; a graphical user interface for the display allowing a user to select a footwear style; a digital imaging device for acquiring a plurality of images of the foot; and a processor operating an image reconstruction algorithm to construct a 3D surface image of the foot using the plurality of acquired foot images.

    The system and method relate to the field of acquiring and digitizing objects, for example, for acquiring and digitizing feet for footwear and/or an orthotic.

    In Figure 1, a footwear system 5 includes an imaging device 10, an operating/computing device 20, an optional fiducial marker system 30, and an optional output/printer/milling device
40. Imaging device 10 includes elements for acquiring a plurality of images of a foot, and in a system, the ankles also. In an arrangement, the imaging device allows for the imaging in both a load and a non-load bearing arrangement. Operating/computing device 20 includes a display; a processor/computer; a graphical user interface; and software. The graphical user interface allows an individual/customer to specify desired footwear style and comfort parameters. The interface also controls the imaging device for acquisition of a plurality of images of the foot. The software allows for the construction of a 3D surface rendering of the foot using the plurality of acquired images that are geometrically accurate and have the precision necessary to achieve the tolerances for the application.

    Fiducial marker system 30 can be used to enable foot surface reconstruction with geometric accuracy. For example, imaging device 10 can project a pattern on the foot. Or alternately, the customer can put on a tight nylon sock with a known pattern (for example, a toe- less, disposable sock). Putting on socks having fiducials before scanning will promote accuracy/stitching/construction of the 3D image. Use of the fiducials can promote 3D surface reconstructions that is geometrically accurate and has the precision necessary to achieve the tolerances for the application.

    Output/printer/milling device generates a shoe last using the 3D surface rendering generated by operating/computing system 20. Using the 3D surface rendering, footwear system 5 can generate/print component parts of a shoe, including mapping the 3D surface rendering to device drive-parameters to custom cut materials for different styles of footwear; and performing the sewing and cementing steps for shoe construction.

    Operating/computing system 20 is utilized for storing the footwear style parameters, the unprocessed (raw) captured images, the parameters used for surface reconstruction, and the reconstructed 3D surface images in a database (e.g., in the cloud) for each customer.

    The processor of system 20 can be remote, in the cloud, or in a cloud-computing arrangement. As such, the reconstruction of the surface renderings can be performed on the processor (CPU) of system 20, on a remote computer, on the "server side" in the cloud, or in a cloud-computing arrangement.

    Imaging device 10 provides a 3D digital image. The imaging device can be a 3D imaging device or a 2D imaging device which allows for the creation/generation of a 3D image from a plurality of 2D images. In particular, the creation/generation of a 3D surface imag...
