Abstract: An augmented reality system in which video imagery of a physical environment is combined with video images output by a game engine by the use of a traveling matte which identifies portions of the visible physical environment by techniques such as Computer vision or chroma keying and replaces them with the video images output by the video game engine. The composited imagery of the physical environment and the video game imagery is supplied to a trainee through a headmounted display screen. Additionally, peripheral vision is preserved either by providing complete binocular display to the limits of peripheral vision, or by providing a visual path to the peripheral vision which is matched in luminance to higher resolution augmented reality images provided by the binocular displays. A software/hardware element comprised of a server control station and a controller onboard the trainee performs the modeling, scenario generation, communications, tracking, and metric generation.

Abstract: A lens aperture of an autostereoscopic camera is moved in a parallax scanning pattern through a plurality of disparity positions offset from the optical axis of the camera lens. Images of a scene being photographed, as viewed through the lens aperture in its various disparity positions, are recorded for subsequent display, which produces a three dimensional illusion when viewed on a conventional display with the unaided eye. The size of the lens aperture and the parallax scanning pattern are adjustable to suit conditions. The lens aperture may be defined by a through-hole in an opaque card, a plurality of interleaved leaf elements, or a planar array of cells switched between transparent and opaque states. In addition to stereoscopic imaging, the moving lens aperture principle of the present invention may be utilized in range-finding and camera image stabilization applications.

Abstract: A support frame is coupled to a counterweight frame to form a mechanical oscillator in which oscillations of adjustable amplitudes are induced to produce parallax, oscillatory scanning motion of a camera rotatable mounted by the support frame. A spring assembly, acting on the support and counterweight frames, establishes an effective spring constant to tune the resonator to a particular resonate frequency. Rotatable motion of the camera relative to the support frame consistently directs the optical axis of the camera to a signal convergence point in the scene being photographed. Separate motors are selectively energized by a control system to regulate the amplitudes of resonator oscillation to a desired disparity setting, to tune the resonator to a desired resonant frequency setting, and to direct the camera to a desired convergence point setting.
