A survey system includes a survey device and a target. The survey device includes a main body rotatable around a vertical axis, a telescope supported by the main body and rotatable around a horizontal axis, a wide angle imaging unit having a second angle of view wider than a first angle of view of the telescope, and a target identification unit configured to identify a target image. The target image is identified based on a differential image between a first image captured by the wide angle imaging unit during an on-period with laser light emitted from an emission unit and a second image captured during an off-period in which laser light is not emitted from the emission unit. The target image is quickly identified even when the target is significantly separated in the horizontal direction from a position directly in front of the survey device.

A selective laser scanner, comprising a target component which can be rotated about two rotation axes and is configured to transmit a distance measuring beam defining a target axis. The selective laser scanner further comprises a distance measuring unit configured to carry out distance measurements by means of the distance measuring beam on cooperative targets or on diffusely scattering targets. The selective laser scanner is equipped with a plurality of overview cameras arranged on the target component offset from the target axis in a fixed positional arrangement with respect to each other having field of views which at least partly overlap each other. The selective laser scanner further comprises a display for displaying an environment image provided by imaging data of at least one of the cameras as well as automatic feature and area detections.
