Method for determining an angular orientation of a log about a longitudinal development axis of the log , the method comprising the following work steps: a first acquisition step, during which one or more first digital photographs are acquired of the lateral surface of the log placed in a reference position, and wherein each first digital photograph is acquired by observing the log from a relative first known viewpoint position; a second acquisition step, during which one or more second digital photographs are acquired of the lateral surface of the log placed in a second position, and wherein each second digital photograph is acquired by observing the log from a relative second known viewpoint position; a first generation step, during which one or more first digital images are generated of the lateral surface of the log placed in the reference position, using the one or more first digital photographs; a second generation step, during which one or more second digital images are generated of the lateral surface of the log placed in the second position, using the one or more second digital photographs; characterized in that it comprises: a comparison step, during which the one or more second digital images are compared with the one or more first digital images to identify a match between a second digital image of the log placed in the second position and a first digital image of the log placed in the reference position; and a determination step, during which the angular orientation of the log in the second position is determined, with reference to a reference angular orientation of the log in the reference position, based on information related to the first digital images and the second digital images for which a match was identified. a first acquisition step, during which one or more first digital photographs are acquired of the lateral surface of the log placed in a reference position, and wherein each first digital photograph is acquired by observing the log from a relative first known viewpoint position; a second acquisition step, during which one or more second digital photographs are acquired of the lateral surface of the log placed in a second position, and wherein each second digital photograph is acquired by observing the log from a relative second known viewpoint position; a first generation step, during which one or more first digital images are generated of the lateral surface of the log placed in the reference position, using the one or more first digital photographs; a second generation step, during which one or more second digital images are generated of the lateral surface of the log placed in the second position, using the one or more second digital photographs; a comparison step, during which the one or more second digital images are compared with the one or more first digital images to identify a match between a second digital image of the log placed in the second position and a first digital image of the log placed in the reference position; and a determination step, during which the angular orientation of the log in the second position is determined, with reference to a reference angular orientation of the log in the reference position, based on information related to the first digital images and the second digital images for which a match was identified. <EOS>
