Claim One:
1. Method for remotely determining an absolute azimuth of a target point (B) in which: a first series of images is acquired (S 1 ) by means of a first piece of equipment ( 1 ), comprising at least one image of a first visual environment from a first location (P 1 ), the location coordinates of which are known; the elements of said images are associated (S 2 ) with absolute azimuth values in a frame of reference centred on said first location (P 1 ); a first image database is constituted (S 3 ), associated with the location coordinates of the first location (P 1 ); said first image database is transferred (S 4 ) to a second piece of equipment ( 2 ), said second piece of equipment ( 2 ) storing said first image database; a second series of images is acquired (S 5 ) by means of said second piece of equipment ( 2 ), comprising at least one image of a second visual environment from a second location (P 2 ), the location coordinates of which are known and from which the target point (B) is visible; at least one point of correspondence is determined (S 6 ) between the first image database and at least one image of the second series of images, said at least one point of correspondence corresponding to a common element (A) shared by both the first and second visual environment; an absolute azimuth (Î¸ 2 ) is attributed (S 7 ) to the common element (A) in a frame of reference centred on the second location (P 2 ); a relative azimuth (Î¸ 3 ) of the target point (B) is determined (S 8 ) in relation to said common element (A), in the frame of reference centred on the second location (P 2 ); an absolute azimuth (Î¸ B ) of the target point (B) is determined (S 9 ) in the frame of reference centred on the second location (P 2 ) by exploiting the absolute azimuth (Î¸ 2 ) in the frame of reference centred on the second location (P 2 ) attributed to the common element (A) and the relative azimuth (Î¸ 3 ) of the target point (B) in relation to said element in the frame of reference centred on the second location (P 2 ).
