摘要： Embodiments are disclosed for adjusting alignment of a near-eye optic of a see-through head-mounted display system. In one embodiment, a method of detecting eye location for a head-mounted display system includes directing positioning light to an eye of a user and detecting the positioning light reflected from the eye of the user. The method further includes determining a distance between the eye and a near-eye optic of the head-mounted display system based on attributes of the detected positioning light, and providing feedback for adjusting the distance between the eye and the near-eye optic.

摘要： A system and related methods for near-eye display of an image are provided. In one example, a near-eye display system includes a light source comprising a surface and a plurality of pixels having a pixel pitch of 5 microns or less. An aperture array is located between 2 mm and 5 mm from the surface of the light source. The aperture array comprises non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a grid of equilateral triangles. The center of each aperture is spaced from the center of each adjacent aperture by an aperture spacing of between 1 mm and 9 mm. The aperture array selectively passes the light emitted from the pixels to display the image without a double image condition.

摘要： A method and apparatus for determining camera pose characterized by six degrees of freedom (e.g., for use in computer vision systems) is disclosed. In one embodiment an image captured by the camera is received, and at least two constraints on the potential pose are enforced in accordance with known relations of the image to the camera, such that the potential pose is constrained to two remaining degrees of freedom. At least one potential pose is then determined in accordance with the remaining two degrees of freedom.

摘要： The present invention is directed toward providing a system for constructing a graphical representation of an image, as perceived from a desired view, from a plurality of calibrated views. An optimum, median fused depth map of a new, desired view of an object or a scene is constructed from a plurality of depth maps of the object or scene, utilizing median values for each of the image pixels within the image domain of the new view. Each of the known depth maps are rendered into the new view, and the pixels of the rendered image are processed one at a time until a median value for each pixel in the new view of the image of the object or scene is calculated. The calculated median values are then assembled into a median fused depth map of the new view of the object or scene, with the median fused depth map available to construct a new two or three dimension images and models of the object or scene as perceived from the new view.

摘要： One or more techniques and/or systems are provided for gaze tracking of one or more users. A user tracking component (e.g., a depth camera or a relatively lower resolution camera) may be utilized to obtain user tracking data for a user. The user tracking data is evaluated to identify a spatial location of the user. An eye capture camera (e.g., a relatively higher resolution camera) may be selected from an eye capture camera configuration based upon the eye capture camera having a view frustum corresponding to the spatial location of the user. The eye capture camera may be invoked to obtain eye region imagery of the user. Other eye capture cameras within the eye capture camera configuration are maintained in a powered down state to reduce power and/or bandwidth consumption. Gaze tracking information may be generated based upon the eye region imagery, and may be used to perform a task.
