Abstract:
The invention provides a surveying instrument capable of performing a non-prism measurement comprising a laser pointer for projecting a laser pointer beam, a measuring unit for emitting a distance measuring light via a telescope unit, for performing distance measurement on a measuring point by receiving a reflected light and for measuring an angle of the measuring point, an image pickup unit for acquiring an image including a target via the telescope unit, a tracking unit for emitting a tracking light via the telescope unit and for tracking the target by receiving a reflection light from the target, a driving unit for rotating the telescope unit in horizontal direction and in vertical direction and a control device for controlling the driving unit so that the reflection light of the tracking light from the target will be positioned at a predetermined position on an image pickup element of the image pickup unit, wherein an optical axis of the distance measuring light and an optical axis of the tracking light are in a known relationship and an optical axis of the laser pointer beam is offset from an optical axis of the tracking light by a predetermined angle.
