Earth observation instrument`s line of sight rolling, pitch/yaw movement restituting method for e.g. satellite, involves calculating variations in line of sight by updating mapping model of images, and restituting movements of line of sight

摘要

The method involves selecting and mapping similar characteristics zones of images of a portion of a scene so as to obtain a position measurement of the zones at respective instants. Angular variations in a line of sight of an observation instrument are calculated between the instants by updating a mapping model of the images. Movements of the line of sight are restituted on time fences by integrating, filtering and re-sampling the variations.
