摘要： Real-time camera tracking using depth maps is described. In an embodiment depth map frames are captured by a mobile depth camera at over 20 frames per second and used to dynamically update in real-time a set of registration parameters which specify how the mobile depth camera has moved. In examples the real-time camera tracking output is used for computer game applications and robotics. In an example, an iterative closest point process is used with projective data association and a point-to-plane error metric in order to compute the updated registration parameters. In an example, a graphics processing unit (GPU) implementation is used to optimize the error metric in real-time. In some embodiments, a dense 3D model of the mobile camera environment is used.

摘要： Systems and methods for reducing interference between multiple infra-red depth cameras are described. In an embodiment, the system comprises multiple infra-red sources, each of which projects a structured light pattern into the environment. A controller is used to control the sources in order to reduce the interference caused by overlapping light patterns. Various methods are described including: cycling between the different sources, where the cycle used may be fixed or may change dynamically based on the scene detected using the cameras; setting the wavelength of each source so that overlapping patterns are at different wavelengths; moving source-camera pairs in independent motion patterns; and adjusting the shape of the projected light patterns to minimize overlap. These methods may also be combined in any way. In another embodiment, the system comprises a single source and a mirror system is used to cast the projected structured light pattern around the environment.

摘要： A method and an apparatus for machining an exterior surface of a metal alloy casing of a portable electronic device to form a combination of a flat edge surface, a curved edge surface and a flat bottom surface is disclosed. The flat edge surface is abraded by contacting a first flat section of a rotating cutting tool along a first circuit of a pre-determined continuous spiral path. The curved edge surface is abraded by contacting a convex section of the rotating cutting tool along additional circuits of the first pre-determined continuous spiral path. The pitch of vertical movement of the cutting tool is adjusted for each circuit of the continuous spiral path based on a resulting curvature of the metal alloy casing. The bottom surface is abraded by contacting a flat section of the cutting tool along a second pre-determined alternating direction linear path.

摘要： Techniques for human body pose estimation are disclosed herein. Images such as depth images, silhouette images, or volumetric images may be generated and pixels or voxels of the images may be identified. The techniques may process the pixels or voxels to determine a probability that each pixel or voxel is associated with a segment of a body captured in the image or to determine a three-dimensional representation for each pixel or voxel that is associated with a location on a canonical body. These probabilities or three-dimensional representations may then be utilized along with the images to construct a posed model of the body captured in the image.

摘要： Three-dimensional environment reconstruction is described. In an example, a 3D model of a real-world environment is generated in a 3D volume made up of voxels stored on a memory device. The model is built from data describing a camera location and orientation, and a depth image with pixels indicating a distance from the camera to a point in the environment. A separate execution thread is assigned to each voxel in a plane of the volume. Each thread uses the camera location and orientation to determine a corresponding depth image location for its associated voxel, determines a factor relating to the distance between the associated voxel and the point in the environment at the corresponding location, and updates a stored value at the associated voxel using the factor. Each thread iterates through an equivalent voxel in the remaining planes of the volume, repeating the process to update the stored value.

摘要： The multistage dry vacuum pump is disclosed, in which it is possible to prevent a pump from being adhesively stuck, which problem occurs due to a difference in thermal expansions between a cylinder body and a rotor, by making thermal expansion conditions between a cylinder body and a rotor of a pump similar by concurrently cooling the cylinder body and the rotor of the pump. The gas passage for transferring gas compressed by each cylinder is provided at each cylinder body in a shape of surrounding an outer side of each cylinder, and a cooling water jacket for circulating cooling water is provided close to an outer side of the gas passage, and a communication passage is formed at a gas passage contacting with the cooling water jacket and is connected with an exhaust space of the cylinder.

摘要： A system and method for providing an augmented reality environment in which the environmental mapping process is decoupled from the localization processes performed by one or more mobile devices is described. In some embodiments, an augmented reality system includes a mapping system with independent sensing devices for mapping a particular real-world environment and one or more mobile devices. Each of the one or more mobile devices utilizes a separate asynchronous computing pipeline for localizing the mobile device and rendering virtual objects from a point of view of the mobile device. This distributed approach provides an efficient way for supporting mapping and localization processes for a large number of mobile devices, which are typically constrained by form factor and battery life limitations.
