  • Patent number: 9269152
    Abstract: Objects within a scene are modeled in two- or three-dimensions by acquiring slices of data from a distributed sensor array and generating the model of the object at least in part from those slices. The distributed sensor array may comprise optical transmitters and optical receivers configured such that they may be individually addressed and activated. The system described herein may be used to support an augmented reality environment.
    Type: Grant

  • Patent number: 9241141
    Abstract: Sensing systems using projection blocks of structured light provide useful information about the surfaces they are projected onto. A camera captures an image which contains a captured block, that is, an image of the projection block interacting with the surface. Corrections may be applied to the captured image to compensate for distortions produced by projector and/or camera systems and produce a corrected image. Noise may be removed from the corrected image using a bilateral filter, producing a filtered image. The filtered image may be processed to determine a boundary of the captured block.

  • Patent number: 9118782
    Abstract: Structured light generated by a projector may be recovered by a camera to determine three-dimensional data about a scene. The structured light signal acquired by the camera may be impaired due to interference from flickering sources of illumination such as lights, electronic displays, and so forth. This optical interference to an image acquisition system, such as a structured light system, is mitigated by modifying operation of a camera by applying a sampling coefficient to the camera's frame rate or by presenting structured light frames during times non-coincident with the interference.
