Title (EN) SYSTEMS AND METHODS FOR ESTIMATING AN OBJECT'S ATTITUDE
(FR) SYSTÈMES ET PROCÉDÉS D'ESTIMATION DE L'ORIENTATION D'UN OBJET
Abstract: front page image
(EN)In general, in one embodiment, a starfield image as seen by an object is analyzed. Compressive samples are taken of the starfield image and, in the compressed domain, processed to remove noise. Stars in the starfield image are identified and used to determine an attitude of the object.
(FR)En général, selon un mode de réalisation de l'invention, l'image d'un champ d'étoiles tel qu'il est vu par un objet est analysée. Des échantillons compressés de l'image du champ d'étoiles sont pris et sont traités dans le domaine compressé afin d'éliminer le bruit. Les étoiles dans le champ d'étoiles sont identifiées et utilisées pour déterminer une orientation de l'objet.
