Star Field Identification Algorithm Research Articles

Experimental verification of the star field identification algorithm in the observatory environment

A six-feature all-sky star field identification algorithm is developed to match approximately detected star fields with reference star fields. It is also integrated with a CCD-based imaging camera. The experimental performance of the star pattern identification algorithm was tested and verified at the Table Mountain Observatory. A set of observatory tests on star fields with this intelligent camera are presented.

Star-Field Identification for Autonomous Attitude Determination

A six-feature all-sky star-field identification algorithm has been developed for autonomous attitude determination. The minimum identifiable star pattern element consists of an oriented star triplet defined by three stars, their celestial coordinates, and their visual magnitudes. This algorithm has been integrated with a charge-coupleddevice- (CCD-) based imaging camera and tested in an observatory environment. The autonomous intelligent camera identifies in real time any star field without a priori knowledge. Observatory tests on star fields with this intelligent camera are described.

Six-feature star-pattern identification algorithm

A six-feature all-sky star-field identification algorithm is developed. The minimum identifiable starpattern element consists of an oriented star triplet defined by three stars, their celestial coordinates, and their visual magnitudes. The performance of the star-pattern identification algorithm is verified through the use of software simulation.

Experimental verification of a star field identification algorithm

A six-feature all-sky star field identification algorithm has been developed, integrated with a CCD-based imaging camera, and tested at the Table Mountain Observatory, California. Calibration of the CCD-based camera to minimize the error in the measured star parameters due to instrument error and experimental conditions is discussed. A set of observatory tests on star fields with this intelligent camera is described.

Autonomous star field identification using intelligent CCD-based cameras

A six-feature all-sky star field identification algorithm has been developed. The minimum identifiable star pattern element consists of an oriented star triplet defined by three stars and their celestial coordinates and visual magnitudes. This algorithm has been integrated with a CCD-based imaging camera. The autonomous intelligent camera identifies in real time any star field without <i>a priori</i> knowledge. Observatory tests on star fields with this intelligent camera are described.

Experimental demonstration of a star-field identification algorithm

A fault-tolerant, six-feature, all-sky star-field identification algorithm has been integrated with a CCD-based imaging camera. This autonomous intelligent camera identifies in real time any star field without a priori knowledge and requires a reference catalog incorporating fewer than 1000 stars. Observatory tests on star fields with this intelligent camera are described.
