Embodiment Construction

[0036] As an example for position determination of a geodetic instrument, figure 1 Schematic representation of typical measurement situations in the construction area. In this case, the total station 1 is positioned as a geodetic instrument with distance and angle measurement functions at a fixed point S which at the same time defines an internal frame of reference relative to the surveying instrument. If an unknown fixed point S is chosen, the total station can also determine its own position absolutely by making a reference measurement relative to the reflector 2 which is placed on a known measured reference point. For this purpose, its point number and measured values ​​are recorded for each reflector 2 in the reference system. After measuring enough reflectors 2 or reference points, according to the relative position of the total station 1 and the reflector 2 and the absolute position of the reflector 2 with respect to the point number assignment in the reference point ta...

Abstract

The invention relates to a position determination method for a geodetic device having a distance and angle measuring functionality, such as a total station (1), a determination being made of the relative location of the geodetic device and reference points (2) marked with reflectors (P1-Pn) of a quantity of reference points, by measuring the distance (D1- Dn) and at least one angle (Phii-Phin, Theta1- Thetan) from the geodetic device to the reference points as reference variables, the reference variables being determined in a device-based reference system. For the reference point quantity formed by the reference points (P1-Pn) and a reference point quantity of measurable reference points (A-G), the positions of which are known in an external reference system, common elements are identified, the relative location of the reference points (P1-Pn) being derived from the reference variables and the common elements being identified and associated based on the relative location of the reference points (P1-Pn). The position (S) of the geodetic device in the external reference system is determined from the common elements and the positions thereof in an external reference system.

Description

technical field [0001] The invention relates to a position determination method for a geodetic instrument according to the preamble of claim 1 . Background technique [0002] In order to record the properties of a specific point in the survey environment, especially for recording data with spatial reference, many surveying methods are known from ancient times. At this time, as the spatial reference data, in addition to possible reference points, the position of the measuring instrument and the direction, distance and angle relative to the measuring point are also recorded. While there are many applications where the geodetic position is known and unknown positions are measured, there are also applications where although several measuring points are known or measured, the position of the measuring device is unknown. [0003] A well-known example of such a surveying instrument, or geodetic instrument, is the theodolite or total station. "Electronic Distance and Direction Mea...
