Abstract: A head-mounted device (HMD) is configured to perform depth detection with a stereo camera pair comprising a first camera and a second camera, both of which are configured to detect/capture visible light and IR light. The fields of view for both of the cameras overlap to form an overlapping field of view. The HMD also includes an IR dot-pattern illuminator that is mounted on the HMD with the cameras and that is configured to emit an IR dot-pattern illumination. The IR dot-pattern illuminator emits a dot-pattern illumination that spans at least a part of the overlapping field of view. The IR dot-pattern illumination adds texture to objects in the environment and enables the HMD to determine depth for those objects, even if they have textureless/smooth surfaces.

Abstract: An imaging system includes an imaging device configured to image an imaging subject on an imaging optical axis, and a calculation unit configured to acquire data relating to a position and/or a size of the imaging subject based on image information acquired by the imaging device through the imaging. The calculation unit acquires change information relating to condition change in the imaging and/or change in the imaging subject on the image. The change is caused by interposition of a light transmitting member when the light transmitting member is interposed on the imaging optical axis during the imaging, and the calculation unit corrects the data based on the change information.

Abstract: The bionic computing system includes a perception subsystem, an attention subsystem, and a temporal-spatial awareness subsystem. The perception subsystem has several perceptual devices for detecting objects from sequences of sensory data and generating an object record for each object. The attention subsystem adjusts the object records by re-identifying the tracking identities across sensory devices, generates several object associations, generate several location associations, and generates several motion implications. The temporal-spatial awareness subsystem organizes and retains the object records in a working memory space.
