Bearing-only SLAM : a vision-based navigation system for autonomous robots [PDF]
, 2008 To navigate successfully in a previously unexplored environment, a mobile robot must be able to estimate the spatial relationships of the objects of interest accurately. A Simultaneous Localization and Mapping (SLAM) sys- tem employs its sensors to build

A model of head direction and landmark coding in complex environments.
PLoS Computational Biology, 2021 Environmental information is required to stabilize estimates of head direction (HD) based on angular path integration. However, it is unclear how this happens in real-world (visually complex) environments.
