Abstract
Embodiments of the present disclosure relate to a scanning device comprising a support base, a calibration pattern disposed on an upper surface of the support base, and a plurality of cameras distributed around an outer perimeter of the support base. In at least one embodiment, the calibration pattern is undetectable or substantially undetectable to the human eye.
Claims20
A scanning device comprising:
- a support base comprising a substantially flat upper surface;
- a calibration pattern disposed on the upper surface, wherein the calibration pattern is undetectable or substantially undetectable by wavelengths in the visible spectrum;
- a plurality of cameras distributed around an outer perimeter of the support base and substantially oriented toward a center of the support base to capture the calibration pattern;
- and
- a processing device operatively coupled to each of the plurality of cameras, wherein the processing device is configured to activate and receive data generated by each of the plurality of cameras.
2 more elements
A method comprising:
- capturing, by each of a plurality of cameras, one or more calibration images of a calibration pattern disposed above a support base of a scanning device, wherein the calibration pattern is undetectable or substantially undetectable by wavelengths in the visible spectrum;
- calibrating each of the plurality of cameras based on the one or more calibration images;
- and
- capturing images of an individual's foot by the plurality of cameras arranged around the support base.
1 more element
A non-transitory computer-readable storage medium having instructions encoded thereon that, when executed by a processing device, cause the processing device to perform a method comprising:
- capturing, by each of a plurality of cameras, one or more calibration images of a calibration pattern disposed above a support base of a scanning device, wherein the calibration pattern is undetectable or substantially undetectable by wavelengths in the visible spectrum;
- calibrating each of the plurality of cameras based on the one or more calibration images;
- and
- capturing images of an individual's foot by the plurality of cameras arranged around the support base.
