METHOD FOR THE SIGNAL EVALUATION OF SIGNALS OF A RANGEFINDER

A method for the evaluation of signals of a rangefinder having at least one sensor point involves carrying out measurements cyclically, wherein the rangefinder emits a plurality of measurement points that indicate a distance from the sensor point. The rangefinder measures distances in a plurality of...

Zusammenfassung:	A method for the evaluation of signals of a rangefinder having at least one sensor point involves carrying out measurements cyclically, wherein the rangefinder emits a plurality of measurement points that indicate a distance from the sensor point. The rangefinder measures distances in a plurality of directions, and a horizontal angle is associated with each measurement point. The measurement points are differentiated into useful signals and interfering signals based on the distance. Measurement points with a distance below a first limiting value are identified as interfering signals, and measurement points above the first limiting value are identified as useful signals. Useful signals are associated with a first measurement area when they satisfy a predetermined condition for distance and horizontal angle. The quantity of useful signals in the first measurement area is determined, and a warning signal is emitted when the quantity of useful signals lies below a first threshold value.
