Toward astrometric calibration of ultrawide-field images
Popis výsledku v původním jazyce
In this paper, we introduce a new method of astrometric calibration tailored especially for ultrawide-field systems like WILLIAM. The standard astrometric solution often fails to provide any result if the processed image contains a large amount of distortion, such as from a fisheye lens. Some algorithms yield the result, but the accuracy is satisfactory only at the center of the field of view. This work analyzes such images and proposes a new method that leads to much higher accuracy and success ratio of the calibration.
