Abstract

With the invention, tree trunks are measured using reflector distance sensors (A1-A49, 1-8), in particular ultrasonic BEROs. The distance sensors (A1-A49, 1-8) are arranged side-by-side in lines. In each case the shortest measurement from one line is accepted as the optimum. This makes possible a simple yet precise measurement.
