Star trackers are primarily optical devices that are used to estimate the
attitude of a spacecraft by recognising and tracking star patterns. Currently,
most star trackers use conventional optical sensors. In this application paper,
we propose the usage of event sensors for star tracking. There are potentially
two benefits of using event sensors for star tracking: lower power consumption
and higher operating speeds. Our main contribution is to formulate an
algorithmic pipeline for star tracking from event data that includes novel
formulations of rotation averaging and bundle adjustment. In addition, we also
release with this paper a dataset for star tracking using event cameras. With
this work, we introduce the problem of star tracking using event cameras to the
computer vision community, whose expertise in SLAM and geometric optimisation
can be brought to bear on this commercially important application.
