System for projecting 3D images and detecting gestures

摘要

A three dimensional (3D) imaging system configured to display an autostereoscopic image of a scene toward a viewing area, and detect gestures occurring in the viewing area. The system includes an imaging device configured to project a plurality of projected images in distinct directions, and each projected image is characterized as a distinct perspective view of the scene. The imaging device is also configured to detect a plurality of received images for the purpose of detecting gestures. The system also includes a holographic diffuser, and a mirror arrangement configured to reflect the plurality of projected images from the imaging device toward the holographic diffuser to display an autostereoscopic image of the scene in the holographic diffuser, and reflect a plurality of perspective images from the viewing area toward the imaging device such that each received image corresponds to a distinct perspective view of the viewing area.

1. A three dimensional (3D) imaging system configured to display an autostereoscopic image of a scene toward a viewing area, and detect gestures occurring in the viewing area, said system comprising:
an imaging device configured to project through a lens a plurality of projected images in distinct directions toward a projection field, wherein each projected image is characterized as a distinct perspective view of the scene, said imaging device also configured to detect through the same lens a plurality of received images from the distinct directions; a holographic diffuser; and a mirror arrangement fixedly positioned in the projection field, said minor arrangement configured to reflect the plurality of projected images from the imaging device toward the holographic diffuser in a manner effective to display an autostereoscopic image of the scene in the holographic diffuser, and reflect a plurality of perspective images from the viewing area toward the imaging device such that each received image corresponds to a distinct perspective view of the viewing area.
