摘要:
The invention relates to a positioning method for determining the position and orientation of a mobile unit having a receiver (3′), whereby the receiver (3′) is detected by a scanner (2′), said scanner (2′) determining at least the distance and a direction in relation to the receiver (3′). The radiation emitted by the sensor is detected by the receiver (3′) and the direction of incidence of radiation and the direction of incidence of radiation in relation to an axis of reception are derived while an offset of the incident radiation in relation to the axis of reception (EA) is determined. Position and orientation of the unit are derived from at least the distance, the direction in relation to the receiver (3′), the offset and the direction of incidence as the position information and the unit is optionally controlled via the optical connection (OV).

An optoelectric angle-measuring device according to the invention has a code carrier having a position code (C1) which can be detected optically as well as a scanning device in the form of a light-sensitive row or area for detecting the position code (C1) and generating a position-dependent scanning signal. The scanning device which is in the form of a scanning film (F1), in particular, surrounds the code carrier or the code carrier essentially completely surrounds the scanning device along a circumference. This provides an extremely accurate angle-measuring device by virtue of the fact that a large part of the position code (C1), in particular even the entire position code (C1), can be detected.

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.

The aim of the invention is to determine the actual position and/or actual orientation of a measuring appliance (4b). To this end, at least two reference points (2b′) lying in a spatial segment (5′) scanned by a laser beam are detected and measured in terms of the distance thereinbetween and the inclination angle thereof. The actual position of the measuring appliance (4b) can be deduced from the known positions of said reference points (2b′) arranged in a detectable manner and the associated distances and inclination angle thereof. The detection, monitoring and measuring of the reference points is carried out by the measuring appliance (4b) in an automated manner, the measuring appliance (4b) and specifically embodied elements associated with the reference points (2b′) forming a local positioning and/or orientation measuring system. The inventive method and corresponding devices enable measurements to be carried out in a problem-free and automated manner, even in areas that cannot be accessed by other measuring systems.

The invention relates to a method for determining at least one influencing variable acting on the eccentricity in a goniometer, using a detector arrangement consisting of four optical detector elements, and a rotational body comprising a plurality of pattern elements arranged around a pattern center, the rotational body being rotatably arranged about an axis. According to said method, at least some of the pattern elements are reproduced on the detector arrangement, the positions of the pattern elements reproduced on the detector arrangement are resolved, and the eccentricity of the pattern center in relation to a detector center of the detector arrangement is determined. A plurality of such eccentricity measurements for different rotational positions enables different influencing variables acting on the current eccentricity to be separated, especially by forming units.
