Abstract
A three-dimensional imaging system uses a single primary optical lens along with three non-collinear apertures to obtain three offset optical channels each of which can be separately captured with an optical sensor.
Claims24
A device comprising:
- an aperture element positioned within a primary optical facility having a center axis, the aperture element including three apertures positioned non-collinearly, each one of the apertures selectively transmitting a portion of an optical wave front of the primary optical facility, thereby providing three optical channels;
- one or more sensors positioned to capture each of the three optical channels, thereby providing three images;
- and a processor adapted to determine displacement of object features between the three images using image registration.
A device comprising an aperture element positioned within a primary optical facility of a triplet imaging system having a center axis, the aperture element including three apertures positioned non-collinearly, each one of the apertures selectively transmitting a portion of an optical wave front of the primary optical facility, thereby providing three optical channels, each carrying a separate image to a sensor, the separate image encoding disparity of object features for use in image triplet processing by the triplet imaging system, wherein one of the three apertures is a center aperture positioned on the center axis.
A device comprising an aperture element positioned within a primary optical facility of a triplet imaging system having a center axis, the aperture element including three apertures positioned non-collinearly, each one of the apertures selectively transmitting a portion of an optical wave front of the primary optical facility, thereby providing three optical channels, each carrying a separate image to a sensor, the separate image encoding disparity of object features for use in image triplet processing by the triplet imaging system, further comprising a fourth aperture, the fourth aperture positioned on the center axis.
A device comprising an aperture element positioned within a primary optical facility having a center axis, the aperture element including three apertures positioned non-collinearly, each one of the apertures selectively transmitting a portion of an optical wave front of the primary optical facility wherein one of the three apertures is a center aperture positioned on the center axis, thereby providing three optical channels carrying three images to one or more sensors adapted for instantaneous capture of each of the three images, further comprising a processor adapted to determine displacement of object features between the three images using image registration.
A device comprising an aperture element positioned within a primary optical facility having a center axis, the aperture element including three apertures positioned non-collinearly, each one of the apertures selectively transmitting a portion of an optical wave front of the primary optical facility wherein one of the three apertures is a center aperture positioned on the center axis, thereby providing three optical channels carrying three images to one or more sensors adapted for instantaneous capture of each of the three images, wherein one of the one or more sensors is positioned to capture a reference image independent of object depth.
