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.

An illumination device (100) includes an illumination unit (1, 2) which illuminates a surface (Ob). The position and the orientation of the illumination unit (1, 2) relative to the surface (Ob) can be changed. A distance sensor (4.1, 8.2) measures an indicator of the current distance between the illumination unit (1, 2) and the surface (Ob). A signal processing control unit (10) is configured to control an output unit (6.1, 6.2) of the illumination unit (1, 2). The controlled output unit (6.1, 6.2) outputs an indication of how much the measured distance deviates from a predetermined reference distance (Ref.sub.1, Ref.sub.2).

A system and method for determination of origin displacement for a laser rangefinding instrument which comprises laser transmitting and receiving sections coupled to a processor section. The processor section is configured to calculate ranges from the instrument to first and second target coordinates and to compensate for displacement between disparate first and second origin points in order to determine a distance between these target coordinates.

A method for generating an activation signal for a warning display of a user of smart glasses. First surroundings sensor signals from the rear and/or lateral surroundings of the user of the smart glasses are received using a processing unit. At least one object in the rear and/or lateral surroundings of the user of the smart glasses is detected as a function of the received first surroundings sensor signals. Second surroundings sensor signals are received as a function of the detected object. First and second motion signals of the user are received. A first movement trajectory of the detected object and a second movement trajectory of the smart glasses user are ascertained. A likelihood of a collision of the user of the smart glasses with the detected object is ascertained as a function of the ascertained first and second movement trajectories.
