Problems solved by technology

This is always very laborious and can be inaccurate and inappropriate for certain conditions, especially for measuring objects with very small horizontal extensions
As already mentioned, the limited availability of the GPS system is also a disadvantage

Embodiment Construction

[0039] figure 1 The laser beam detector 1 is shown for determining the incident point 9 which is used for the azimuth determination method. In the method of the present invention, the laser source 6 emits the first laser beam 7 to the detector 1, where the exit direction is defined. The detector 1 detects the first laser beam 7 at about the same time.

[0040] The detector 1 has a plurality of detection areas, for example 72 detection areas, which are arranged adjacent to each other on a cylindrical surface around a vertical axis. The detection area 2 of the detector 1 is the area of ​​all the detection areas 3. Each detection area 3 covers, for example, a 5° angle range, thereby obtaining a detection area of ​​the detector 1 segmented within a 360° planar angle range, and the detection area has a corresponding number of discrete partial detection areas 17. Each partial detection area 17 is fixedly assigned a predetermined partial detection direction, for example, as a directio...

Abstract

The invention relates to a system for determining a position by emitting a first laser beam (7) by a laser source (6) positioned in a reference system onto a detector (1) and simultaneously detecting the first laser beam (7) by the detector (1), thus defining an emission direction of the laser source (7). The detector (1) has a segmented detection area comprising a plurality of discrete partial detection areas (17), each having a defined partial detection direction and at least two partial detection directions thereof being different. When detecting the first laser beam (7), an impingement point (9) of the first laser beam (7) on the detector (1) is detected by means of at least one partial detection area (17), and when determining the incidence direction (10), said direction is derived from the at least one partial detection direction. The location of the detector (1) relative to the laser source (6) and the reference system is then determined using the emission direction and the incidence direction (10).

Description

Technical field [0001] The present invention relates to an orientation determination method according to the preamble of claim 1, the application of the orientation determination method, a laser beam detector and a detector reflector device according to the preamble of claim 7. Background technique [0002] The determination of the position of an object such as a mobile machine by means of a total station, that is, the determination of the position and / or direction, has been known for a long time. Here, for example, a reflecting prism is mounted on the object at a known position relative to the object, and the reflecting prism is measured with a laser beam by means of a total station. The total station receives the reflected beam. The distance between the reflector and the total station is derived by means of the phase difference or time difference between the emitted and received beams, and the solid angle (Raumwinkel) of the object relative to the total station is detected acc...
