Abstract
Apparatuses and methods are disclosed for capturing three-dimensional images, particularly of all or parts of human subjects and employing polarization. In disclosed implementations, cross-polarized, whole-body images of human subjects can be captured.
Claims20
A three-dimensional imaging apparatus comprising:
- a plurality of image capture devices, each image capture device including polarized filtering of a first orientation and belonging to one of a number of groups of image capture devices;
- a plurality of illumination sources, each illumination source including polarized filtering of a second orientation orthogonal to the first orientation and belonging to one of a number of groups of illumination sources, each of the groups of image capture devices corresponding to one of the groups of illumination sources;
- a support structure, wherein the plurality of image capture devices and the plurality of illumination sources are mounted on the support structure;
- and
- a controller, wherein the controller is configured to control the plurality of image capture devices and the plurality of illumination sources to sequentially activate each of the groups of image capture devices and each of the groups of illumination sources, wherein each group of illumination sources is activated while the corresponding group of image capture devices is activated.
A method of operation of a three-dimensional imaging apparatus comprising a plurality of image capture devices, each image capture device including polarized filtering of a first orientation and belonging to one of a number of groups of image capture devices, and a plurality of illumination sources, each illumination source including polarized filtering of a second orientation orthogonal to the first orientation and belonging to one of a number of groups of illumination sources, each of the groups of image capture devices corresponding to one of the groups of illumination sources, the method comprising:
- sequentially activating each of the groups of image capture devices;
- and
- sequentially activating each of the groups of illumination sources, wherein each group of illumination sources is activated while the corresponding group of image capture devices is activated.
A cross-polarization imaging apparatus comprising:
- an image capture device, the image capture device including polarized filtering of a first orientation;
- an illumination source, the illumination source including polarized filtering of a second orientation orthogonal to the first orientation;
- a housing configured to house the image capture device and the illumination source;
- and
- circuitry configured to interoperate with the image capture device, the illumination source and a controller, so that the controller can control the image capture device and the illumination source.
