Abstract: A method for identifying a plurality of blades of an engine. The method can include obtaining and recording a reference view captured by a vision system of an initial, or first, blade of a plurality of blades of the engine at a first blade position, such as an inspection position. The positions of other blades that are to be subsequently identified and/or cataloged can be evaluated by a controller from information captured by the vision system and the reference view to determine if the subsequent blade is at the first blade position. If a blade is determined to not be at the first blade position, the controller can generate an error signal indicative of an amount an actuator is to be operated to displace the blade to the first blade position. The controller can compare information captured from the image of a blade with stored data to identify the blade.
