A surveying device including a base defining a base axis, a support structure rotatable around the base axis and defining a rotation axis, a light emitting unit emitting light and a light receiving unit for detecting reflected light. A rotation unit is mounted on the support structure for emitting and receiving light in defined directions, wherein the rotation unit comprises a rotation body rotatable around the rotation axis including a scanning mirror arranged tilted relative to the rotation axis. An imaging unit for capturing an image of a scanning region is provided. The imaging unit comprises a camera fixedly arranged on the support structure, the rotation body comprises at least one reflecting deflecting surface assigned to the camera. The imaging unit and the rotation body are arranged so that the field of view comprises a defined field angle around the rotation axis.
