Abstract
Surveying device comprising a base defining a base axis (A), a support structure arranged to be rotatable around the base axis (A) and defining a rotation axis (B), a light emitting unit for emitting measuring signal and a light receiving unit comprising a detector for detecting reflected measuring signal. A rotation unit is mounted on the support structure for providing emission and reception of measuring light in defined directions, wherein the rotation unit comprises a rotation body which is mounted rotatable around the rotation axis (B) and the rotation body comprises a scanning mirror which is arranged tilted relative to the rotation axis (B). The device comprises at least one projector fixedly arranged with the support structure, defining a particular optical axis and configured to direct a light pattern at a scene, wherein position and shape of the pattern are controllable by the controlling and processing unit.
