Theodolite measuring system

The theodolite measuring system implements a geometric-optical measuring method with theodolites , which has found its way into industrial measuring technology .

Procedure of measuring

The measuring system is a two or more theodolite measuring system for measuring 3-D coordinates by making use of the spatial forward section is. In this case, an identical by at least two theodolites point targeted in the space (signaled point or marking z., Via laser) and each device registers horizontal and vertical angles . If the orientation of all theodolites to one another is known, the 3D coordinate of the targeted point can be calculated from the forward section.

The orientation of the theodolites to one another is determined via an orientation measurement that corresponds to a bundle block adjustment . The scale of the measurement must be brought into the measurement by measuring a known length. The accuracy of the measurement "[...] depends not only on the sensors used, but also on the recording constellation (location of the connection points and the object to be measured)."
