Abstract
A surveying device including a base defining a base axis (A), a support structure defining a rotation axis (B), a light emitting unit, a light receiving unit detecting reflected measuring light, and a rotation unit including a rotation body including at least one scanning mirror arranged tilted relative to the rotation axis (B) and a curved deflecting element different from the scanning surface. The surveying device also includes an imaging unit including a camera sensor which is fixedly arranged so that an optical axis of the camera sensor is directed towards the rotation body, such that only in a predetermined imaging-alignment of the rotation body around the rotation axis (B) the optical axis of the at least one camera sensor is deflected by the curved deflecting element by a desired angle and direction so that the field of view comprises a defined field angle around the rotation axis (B).
