摘要： A system and method executable by a computing device of an augmented reality system for registering a camera in a physical space is provided. The method may include identifying an origin marker in a series of images of a physical space captured by a camera of an augmented reality system, and defining a marker graph having an origin marker node. The method may further include analyzing in real-time the series of images to identify a plurality of expansion markers with locations defined relative to previously imaged markers, and defining corresponding expansion marker nodes in the marker graph. The method may further include calculating a current position of the camera of the augmented reality system in the physical space based on a location of a node in the marker graph corresponding to a most recently imaged marker, relative to the origin marker and any intermediate markers.

摘要： Systems and methods for mesh generation from depth images are provided. According to one aspect, a method executable by a compression device for sending compressed depth information is provided. The method may comprise, at a compression module executed on the compression device, receiving a depth image of a scene from a depth camera. The depth image may include a matrix of pixels, each pixel in the matrix including a depth value indicating a depth of an object in the scene observed at that pixel. The method may further comprise compressing the depth image into a tree data structure, and sending the tree data structure via a communication path to a rendering device for generating a mesh of the scene at the rendering device.
