Abstract
For determining the load of an excavator bucket, or optionally of another holding region, a measurement step and an evaluation step are carried out. In the measurement step, the position of a load surface is determined by a noncontact distance-measuring device and, in the evaluation step, a load volume is determined from the position of the load surface and the position and shape of the excavator bucket or of the holding region. For determining the position of the load surface, at least one two-dimensional matrix with distance values is created by means of a distance-measuring camera. For determining the position of the excavator bucket, the distances to at least three points of the excavator bucket, in particular to points on the upper bucket edge, optionally to marked points are determined using the distance-measuring apparatus for determining the surface.
