Abstract
In one embodiment, a method includes determining correspondence data between a sequence of images based on identified features in the sequence of images and predicted pose based on motion data, and determining current state information based on the correspondence data and the motion data. The current state information comprises at least a current pose of the wearable device relative to the environment capture by the one or more cameras. Furthermore, the method comprises receiving map points in a three-dimensional map and their associated descriptors based on the identified features in the sequence of images and identifying one or more of the map points in the sequence of images based on the associated descriptors associated with the map points. The current state information is further determined based on the identified one or more of the map points.
