摘要： Techniques are disclosed for performing image space reprojection iteratively. An insignificant parallax threshold depth is computed for a source image. Portions of the image having depth values greater than the insignificant parallax threshold depth may be shifted uniformly to produce corresponding portions of the reprojection (target) image. An iterative fixed-point reprojection algorithm is used to reproject the portions of the source image having depth values less than or equal to the insignificant parallax threshold depth. The fixed point reprojection algorithm quickly converges on the best pixel in the source image for each pixel in a target image representing an offset view of the source image. An additional rendering pass is employed to fill disoccluded regions of the target image, where the reprojection algorithm fails to converge.

摘要： A method is provided for an optimized stereoscopic camera with low processing overhead, especially suitable for real-time applications. By constructing a viewer-centric and scene-centric model, the mapping of scene depth to perceived depth may be defined as an optimization problem, for which a solution is analytically derived based on constraints to stereoscopic camera parameters including interaxial separation and convergence distance. The camera parameters may thus be constrained prior to rendering to maintain a desired perceived depth volume around a stereoscopic display, for example to ensure user comfort or provide artistic effects. To compensate for sudden scene depth changes due to unpredictable camera or object movements, as may occur with real-time applications such as video games, the constraints may also be temporally interpolated to maintain a linearly corrected and approximately constant perceived depth range over time.

摘要： An augmented reality (AR) audio system for augmenting environment or ambient sound with sounds from a virtual speaker or sound source positioned at a location in the space surrounding an AR participant. The sound from the virtual speaker may be triggered by an action of the listener and/or by the location or relative orientation of the listener. The AR audio system includes stereo earphones receiving an augmented audio track from a control unit, and binaural microphones are provided to capture ambient sounds. The control unit operates to process trigger signals and retrieve one or more augmentation sounds. The control unit uses an AR audio mixer to combine the ambient sound from the microphones with the augmentation sounds to generate left and right ear augmented audio or binaural audio, which may be modified for acoustic effects of the environment including virtual objects in the environment or virtual characteristics of real objects.
