Abstract: A depth camera assembly (DCA) includes a projector, a detector and a controller. The projector emits a tiled structured light (SL) pattern onto a local area. Each illumination source of the projector includes one or more light emitters and an augmented diffractive optical element (ADOE) designed with a pattern mask. The ADOE diffracts at least a portion of light beams emitted from the light emitters to form a first SL pattern projection having a field-of-view corresponding to a first tileable boundary. The pattern mask prevents projection of light that would otherwise be diffracted outside the first tileable boundary. The first SL pattern projection is combined with at least a second SL pattern projection into the tiled SL pattern illuminating objects in the local area. The detector captures images of the objects illuminated by the SL pattern. The controller determines depth information for the objects using the captured images.

Abstract: The disclosed computer-implemented method may include comprising identifying, within a real-world environment, a position of a user relative to a safety boundary. The position of the user is identified by a head-mounted display system comprising a display device. The display device is configured to at least partially obscure visibility of the real-world environment to the user. The method may further include selecting, based on the position of the user, at least a portion of a model of the real-world environment, rendering the portion of the model of the real-world environment, and displaying the rendered portion of the model of the real-world environment via the display device as a notification of the position of the user relative to the safety boundary. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A depth camera assembly (DCA) captures data describing depth information in a local area. The DCA includes an array detector, a controller, and an illumination source. The array detector includes a detector that is overlaid with a lens array. The detector includes a plurality of pixels, the plurality of pixels are divided into a plurality of different pixel groups. The lens array includes a plurality of lens stacks and each lens stack overlays a different pixel group. The array detector captures one or more composite images of the local area illuminated with the light from the illumination source. The controller determines depth information for objects in the local area using the one or more composite images.

Abstract: A depth camera assembly (DCA) that captures data describing depth information in a local area. The DCA includes an imaging device, a controller, and an illumination source. The illumination source includes a plurality of emitters on a single substrate. The imaging device captures one or more images of the local area illuminated with the light from the illumination source. The controller determines depth information for objects in the local area using the one or more images.

Abstract: A sensor apparatus may include an array of protruding members that each extend outward in a different radial direction from a central axis, each protruding member including a projector that projects structured light into a local environment, one or more cameras that capture reflections of the structured light from the local environment, and another camera that captures visible-spectrum light from the local environment. The sensor apparatus may also include one or more localization devices for determining a location of the sensor apparatus. Various other apparatuses, systems, and methods are also disclosed.
