Abstract
The invention relates to a process and device for the rapid detection of the position of a target marking. The target marking is picked-up by imaging optics and a local opto-electronic detector of a theodolite or tachymeter. Electric signals from the detector are rapidly evaluated in a pre-processing unit by formation of sum functions for determining coordinates of the target marking in such a way that the target marking is immediately automatically detected in coarse targeting and its further movement can be followed automatically. Its track data can simultaneously be recorded.
