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.

摘要： Systems and methods are disclosed for describing and tracking edges within the field of view of one or more imaging devices. In one example, the present system defines a row of pixels taken across a width of the edge, and then determines a binary edge descriptor for the edge by comparing at least one of grayscale values and contrast of pixels within respective pixel pairs from the row of pixels, the result of the comparisons setting bits within the binary descriptor.

摘要： A system and method are disclosed for recognizing and tracking a user's skeletal joints with a NUI system. The system includes one or more experts for proposing one or more skeletal hypotheses each representing a user pose within a given frame. Each expert is generally computationally inexpensive. The system further includes an arbiter for resolving the skeletal hypotheses from the experts into a best state estimate for a given frame. The arbiter may score the various skeletal hypotheses based on different methodologies. The one or more skeletal hypotheses resulting in the highest score may be returned as the state estimate for a given frame. It may happen that the experts and arbiter are unable to resolve a single state estimate with a high degree of confidence for a given frame. It is a further goal of the present system to capture any such uncertainty as a factor in how a state estimate is to be used.

摘要： A method of tracking a target includes receiving from a source an observed depth image of a scene including the target. Each pixel of the observed depth image is labeled as either a foreground pixel belonging to the target or a background pixel not belonging to the target. Each foreground pixel is labeled with body part information indicating a likelihood that that foreground pixel belongs to one or more body parts of the target. The target is modeled with a skeleton including a plurality of skeletal points, each skeletal point including a three dimensional position derived from body part information of one or more foreground pixels.
