Abstract:
1. A method for determining a spatial position of a hand-held measuring appliance, wherein a quantity of reference points have been made detectable, the quantity of reference points comprising at least two reference points, and wherein the hand-held measuring appliance is configured to detect and measure the reference points by means of laser radiation, the method comprising the following acts: deriving positions of the reference points by surveying the reference points from at least one known initial position; automatically detecting and deriving location information relative to at least one first and one second reference point from the quantity of reference points using the measuring appliance, wherein at least one spatial segment is automatically scanned in a scanning movement by the laser radiation to detect the first and second reference points; and wherein the location information for at least the detected first and second reference points is derived by measuring at least: deriving an actual position of the measuring appliance from the location information and the positions of at least the first and second reference point.
