Abstract
The invention relates to a method for updating and/or for initializing, in a system comprising an image sensor oriented towards the horizon such as a pair of binoculars coupled to a geographical north seeker incorporating a gyrometer, a value representative of the orientation of the image sensor with respect to north, in which the shift of two images arising from the digital image sensor is determined at a first instant and at a second instant that are distinct so as to construct an item of information representative of an angular movement, and in which this angular movement information is utilized to: update the value of orientation of the image sensor;—and/or to discriminate the movements of the image sensor with respect to the ground from the movements of the image sensor that are due to the rotation of the earth, in a process for initializing the value of orientation of the image sensor using a north seeker of gyroscopic or gyrometric type rigidly tied to the image sensor.
