Abstract: A method for updating camera poses includes receiving a set of captured depth maps associated with a scene and detecting a first shape and a second shape present in the scene. The method also includes, for each of the first shape and the second shape, creating a 3D mesh, creating a virtual camera associated with the 3D mesh, and rendering a depth map associated with the virtual camera. The method further includes identifying a subset of the captured depth maps such that each captured depth map in the subset contains at least a portion of either the first shape or the second shape. The method additionally includes updating the physical camera poses by jointly solving for the physical camera poses by optimizing an alignment between the first depth map, the second depth map, and the subset of the set of captured depth maps.

Abstract: An augmented reality/mixed reality system that provides a more immersive user experience. That experience is provided with increased speed of update for occlusion data by using depth sensor data augmented with lower-level reconstruction data. When operating in real-time dynamic environments, changes in the physical world can be reflected quickly in the occlusion data. Occlusion rendering using live depth data augmented with lower-level 3D reconstruction data, such as a raycast point cloud, can greatly reduce the latency for visual occlusion processing. Generating occlusion data in this way may provide faster operation of an XR system using less computing resources and enabling the system to be packaged in a battery operated wearable device.
