Abstract

The present disclosure relates to a method (200) for estimating information related to a vehicle pitch and/or roll angle. The method comprises a step of obtaining (220) a first estimate of the information related to the pitch and/or roll angle. The method is characterized by the steps of capturing (210) an image of an area covering at least a part of the horizon using a camera mounted on the airborne vehicle, and determining (240) an improved estimate of the information related to the pitch and/or roll angle based on the first estimate of the information related to the pitch and/or roll angle, and a digital elevation model.
