Problems solved by technology

Another problem can be related, for example, to the situation where line-of-sight contact between the total station or theodolite and the cooperating target is lost due to an obstacle, and the "refound" cooperating target, which is then tracked and continuously measured, must be assigned to the machine's specific reference point

Embodiment Construction

[0021] figure 1 A total station or theodolite 51 according to the prior art is shown, in this case the total station 51 comprising a tracking unit 55 with an image acquisition unit (here exemplary a panoramic camera), wherein , the acquisition direction of the image acquisition unit is largely parallel to the measurement direction of the measuring device also arranged in the total station or theodolite. The light acquisition axis of the integrated image acquisition unit therefore extends at least parallel to, in particular coaxial with, the measurement axis defined by the measurement radiation that can be emitted. The field of view of the image acquisition unit is limited by the optical unit installed in the tracking unit 55 and by the configuration of the tracking unit 55 , wherein the measurement radiation is likewise emitted through the optical unit and thus the direction of the measurement radiation is limited.

[0022] Furthermore, the total station or theodolite 51 is p...

Abstract

The invention relates to a system being configured for confirming a mobile cooperative target being automatically tracked and measured by a total station or theodolite in order to automatically control a machine operation of a construction site machine, comprising at least one total station or theodolite with a UWBST anchor-module having an anchor-ID, and a cooperative target associated with a UWBST tag-module having a tag-identifier (tag-ID) and being used for automatically controlling a machine operation of the construction site machine. The system further comprises a machine control unit associated with the construction site machine configured for controlling machine operations based on tracking and continuously measuring cooperative targets wherein tracking and continuously measuring is carried out by the total station or theodolite, and an ultra-wide band (UWB) distance meter associated with the UWBST anchor-module configured for measuring a distance (UWB-distance) between the UWBST anchor-module and the UWBST tag-module. The measured UWB-distance with the assigned tag- and anchor-IDs is then provided to the machine control unit, wherein the machine control unit is configuredfor matching measured optical distances to measured UWB-distances and using the matching as confirmation that the cooperative target being tracked and continuously measured by the total station or theodolite is the cooperative target being used for automatically controlling the machine operation.

Description

technical field [0001] The present invention relates to a system for improving the automatic control of machine operations of construction site machinery. Background technique [0002] Since ancient times, various geodetic methods and geodetic equipment have been known for the purpose of measuring cooperative objects. A tachymeter, total station or theodolite provide generally known examples of such measuring and / or geodetic devices. Such a device has an angle measuring function and a distance measuring function allowing determination of direction and distance to and from a selected cooperation target. In this case, the angle and distance variables are determined in the device's internal reference frame and, if appropriate, must also be linked to an external reference frame (e.g. a coordinate system for absolute position determination). [0003] Modern total stations or theodolites have microprocessors for further digital processing and storage of the acquired measurement ...
