    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： Devices and techniques are described for automatically calibrating a camera system. The camera system undergoing calibration is coupled to a computing device and an automated positioning platform coupled to a target structure. The computing device acquires images from the camera of the target structure in a plurality of repeatable poses. From these acquired images, intrinsic camera parameters may be determined. Once determined, the parameters may be used to correct images acquired by the camera system.

    摘要： An augmented reality environment allows interaction between virtual and real objects. Various surfaces within the environment such as walls, tables, countertop, chairs, floor, ceiling, and so forth may be used as projection surfaces. Qualified projection surfaces are determined, and an initial projection surface is selected for use from these. This selection may take into account user preferences, user orientation, types of image to be projected, and so forth. Other qualified projection surfaces may have visual indicators projected thereon, indicating relative suitability for use as a projection surface.
