Method for determining an angular orientation of a log (2) about one of its longitudinal development axes, comprising a first generation step, during which one or more first digital images are generated of the lateral surface of the log placed in a reference position, using one or more first digital photographs, a second generation step, during which one or more second digital images are generated of the lateral surface (1) of the log (2) placed in a second position using the one or more second digital photographs, a step of comparing the one or more second digital images with the one or more first digital images, and a step of determining the angular orientation of the log (2) in the second position with reference to a reference angular orientation of the log (2) in the reference position, based on information related to the first digital images and the second digital images for which a match was identified. Also claimed is a device which can implement is programmed to perform the following of the steps described above: the second generation step, the comparison step and the determination step.

A log processing head with a top knife and moveable feed means and delimbing and/or debarking means pushing a log against the top knife by means of actuators. In order to allow the top knife to follow the contour of the log without damaging a pin holding the knife, a pivot joint is used between the knife and the connection of the pin on the structure.
