    摘要: Detecting material properties such reflectivity, true color and other properties of surfaces in a real world environment is described in various examples using a single hand-held device. For example, the detected material properties are calculated using a photometric stereo system which exploits known relationships between lighting conditions, surface normals, true color and image intensity. In examples, a user moves around in an environment capturing color images of surfaces in the scene from different orientations under known lighting conditions. In various examples, surfaces normals of patches of surfaces are calculated using the captured data to enable fine detail such as human hair, netting, textured surfaces to be modeled. In examples, the modeled data is used to render images depicting the scene with realism or to superimpose virtual graphics on the real world in a realistic manner.

    摘要: Provided is a method of spatially referencing a plurality of images captured from a plurality of different locations within an indoor space by determining the location from which the plurality of images was captured. The method may include obtaining a plurality of distance-referenced panoramas of an indoor space. The distance-referenced panoramas may each include a plurality of distance-referenced images each captured from one position in the indoor space and at a different azimuth from the other distance-referenced images, a plurality of distance measurements, and orientation indicators each indicative of the azimuth of the corresponding one of the distance-referenced images. The method may further include determining the location of each of the distance-referenced panoramas based on the plurality of distance measurements and the orientation indicators and associating in memory the determined locations with the plurality of distance-referenced images captured from the determined location.

    摘要: Provided is an image that is comfortably viewed and operated by a user. An electronic device acquires user information related to a relative position between a user and a display unit. Then, the electronic device transmits the user information to an information processing device. The information processing device includes a communication unit and a control unit. The communication unit receives the user information related to the relative position of the user and a display unit which is acquired by the electronic device from the electronic device. Further, the control unit performs control to decide a display mode of an image transmitted from a source device on the display unit on the basis of the user information received from the electronic device.

    摘要: A plate for a 3D scanning system can include a plate body configured to mount to a 3D scanning system, and a plurality of artifact alignment apertures defined in the plate body arranged in a predetermined pattern to allow a predetermined mounting arrangement of one or more artifacts. The artifact alignment apertures are configured to allow an artifact to be mounted to the plate body.
