摘要： A real-time stereo video signal of a captured scene with a physical foreground object and a physical background is received. In real-time, a foreground/background separation algorithm is used on the real-time stereo video signal to identify pixels from the stereo video signal that represent the physical foreground object. A video sequence is produced by rendering a 3d virtual reality based on the identified pixels of the physical foreground object.

摘要： X-ray examination of objects, which may be very large objects such as aircraft, boat hulls or lengthy pipelines, is accomplished with an x-ray source (22) having a moving x-ray origin point (29) that is scanned in a raster pattern (33). At least one x-ray detector (23) having a very small x-ray sensitive area (38) is disposed behind or within the object (41) and provides an output signal indicative of internal characteristics of an adjacent region of the object (41). The source (22) and detector (23) undergo relative travel at least in a lateral direction during the examination to provide a sequence of different x-ray views that may include views of successive regions of the object (41), views from different angles and stereo views. X-ray images are produced at one or more monitor screens (43) by sweeping a point of light in a raster pattern corresponding to that (33) of the x-ray source (22) while modulating the intensity of the point of light in accordance with the output signal of the detector (23). An array (39) of spaced apart detectors (23) may be used to simplify examination of large objects or to speed examination of small objects.

摘要： A flat screen autostereoscopic display for bright wide angle stereoscopic images employs a flat screen on which are displayed a plurality of regularly spaced discrete, finite light emitting sites such as thin, vertical light emitting lines. A light valve located in front of the screen forms images by means of varying the transparency of individual pixels arranged in a raster pattern across its surface. The screen and light valve are arranged in such a way that an observer sees the light emitting lines through one set of pixels with the left eye and the same lines through a different set of pixels with the right eye. A mask may be used with the display unit to enhance the parallax effect obtained by the viewer. The autostereoscopic effect is obtained when the viewer sees with the right eye and the left eye either alternating rows or alternating columns of pixels.

摘要： Embodiments of the invention provide systems and methods for three-dimensional imaging with wide field of view and precision timing. In accordance with one aspect, a three-dimensional imaging system includes an illumination subsystem configured to emit a light pulse with a divergence sufficient to irradiate a scene having a wide field of view. A sensor subsystem is configured to receive over a wide field of view portions of the light pulse reflected or scattered by the scene and including: a modulator configured to modulate as a function of time an intensity of the received light pulse portion to form modulated received light pulse portions; and means for generating a first image corresponding to the received light pulse portions and a second image corresponding to the modulated received light pulse portions. A processor subsystem is configured to obtain a three-dimensional image based on the first and second images.
