A six-feature all-sky star field identification algorithm has been dev
eloped. The minimum identifiable star pattern element consists of an o
riented star triplet defined by three stars and their celestial coordi
nates and visual magnitudes. This algorithm has been integrated with a
CCD-based imaging camera. The autonomous intelligent camera identifie
s in real time any star field without a priori knowledge. Observatory
tests on star fields with this intelligent camera are described.
