Abstract
A reflector arrangement for position determination and/or marking of target points, comprising a retroreflector and a first sensor arrangement, by means of which the orientation measurement radiation passing through the retroreflector is acquirable. The first sensor arrangement comprises a first optical assembly providing a fisheye lens, and a first sensor, wherein the retroreflector and the first sensor arrangement are arranged in such a way that orientation measurement radiation passing through the retroreflector is projectable onto the detection surface of the first sensor by means of the first optical assembly.
Claims15
A reflector arrangement for position determination or marking of target points, the reflector arrangement comprising:
- a retroreflector, which:
- provides a position determination for the reflector arrangement by means of parallel measurement beam reflection, and
- provides a passage surface for at least one part of measurement radiation entering the retroreflector as an orientation measurement radiation;
- and
- a first sensor arrangement, by means of which the orientation measurement radiation passing through the retroreflector is acquirable, wherein the first sensor arrangement includes:
- a first optical assembly, and
- a first sensor,
- wherein the retroreflector and the first sensor arrangement are arranged in such a way that the orientation measurement radiation passing through the retroreflector is deflectable onto a detection surface of the first sensor by means of the first optical assembly.
