Abstract
A method is for determining a sharpness condition of a saw chain of a chain saw. The saw chain includes at least one cutting link having an upper cutting blade. An upper cutting blade image of the upper cutting blade of the cutting link is recorded using an imaging device. An evaluation of the upper cutting blade image is performed using an evaluation unit, which includes an artificial neural network. A sharp condition and a dull condition of the saw chain are defined in the evaluation unit. The saw chain is assigned on the basis of the upper cutting blade image using the artificial neural network to the sharp condition or the dull condition.
