摘要:
Methods, systems, and computer readable media for low latency stabilization for head-worn displays are disclosed. According to one aspect, the subject matter described herein includes a system for low latency stabilization of a head-worn display. The system includes a low latency pose tracker having one or more rolling-shutter cameras that capture a 2D image by exposing each row of a frame at a later point in time than the previous row and that output image data row by row, and a tracking module for receiving image data row by row and using that data to generate a local appearance manifold. The generated manifold is used to track camera movements, which are used to produce a pose estimate.
