    摘要： Objects and their placement within a particular scene may be characterized using structured light with no or minimal manual intervention or calibration to the scene. The structured light pattern may be rendered with visible light, yet imperceptible to users, by generating a set of opposing excursions in one or more image properties for durations which are shorter than the integration time of the human eye. A set of assumptions and ongoing testing of those assumptions against physical objects identified within the environment allows characterization of the scene and the objects therein.

    摘要： An architecture includes a system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The augmented reality environment is hosted within a surrounding area in which various ambient conditions, external to the augmented reality environment, persist. The architecture monitors the external conditions and controls secondary devices that selectively modify the conditions as desired in cooperation with operation of the augmented reality environment to effectively enhance user experience. Alternatively or additionally, the architecture may inform the user of what changes to make, and the user manually makes the adjustments.

    摘要： Devices and techniques are described for generating three-dimensional (3D) models of objects. Depth data acquired from a depth camera system is used with data about surface normals to generate a 3D model of the object. The depth camera system may use cameras or projectors with different baseline distances to generate depth data. The use of different baseline distances may improve accuracy of the depth data. The data about surface normals may be calculated from images acquired when the object is illuminated from different angles. By using the depth data and relative depth changes from the surface normal data, high resolution spatial data may be generated at high frame rates. Data from multiple baseline distances may also be combined to improve performance.

    摘要： Structured light patterns are projected onto an object and images of the structured light interacting with the surface of the object are acquired, as well as grayscale information. Edges within the structured light patterns are detected and depth sample points on the edges are used to determine distance to those sample points. The grayscale information is used to construct surface normals. From these normals relative surface contours such as curves or slopes may be determined. A model of a surface of the object is generated using the distances and the contours.
