Abstract
A sensor assembly for determining one or more features of a local area is presented herein. The sensor assembly includes a plurality of stacked sensor layers. A first sensor layer of the plurality of stacked sensor layers located on top of the sensor assembly includes an array of pixels. The top sensor layer can be configured to capture one or more images of light reflected from one or more objects in the local area. The sensor assembly further includes one or more sensor layers located beneath the top sensor layer. The one or more sensor layers can be configured to process data related to the captured one or more images. A plurality of sensor assemblies can be integrated into an artificial reality system, e.g., a head-mounted display.
Claims20
A sensor assembly comprising:
- a first sensor layer, of a plurality of stacked sensor layers, including an array of pixels configured to capture one or more images of light reflected from one or more objects in a local area;
- and
- one or more sensor layers of the plurality of stacked sensor layers located in the sensor assembly beneath the first sensor layer, the one or more sensor layers configured to process data related to the captured one or more images.
A head-mounted display (HMD) comprising:
- an electronic display configured to emit image light;
- an illumination source configured to illuminate a local area with light;
- a plurality of sensor assemblies, each sensor assembly of the plurality of sensor assemblies comprising:
- a first sensor layer, of a plurality of stacked sensor layers, including an array of pixels configured to capture one or more images of at least a portion of the light reflected from one or more objects in the local area, and
- one or more sensor layers of the plurality of stacked sensor layers located beneath the sensor layer, the one or more sensor layers configured to process data related to the captured one or more images;
- and
- an optical assembly configured to direct the image light to an eye box of the HMD corresponding to a location of a user's eye,
- wherein depth information for the local area is determined by at least one of the plurality of sensor assemblies based in part on the processed data.
