摘要
The invention relates to a geodesic measurement system (1) having a geodesic measurement device (2), in particular theodolite or total station and a plurality of target objects (11) that form a target object volume. A unique identification code (ID) is allocated to each of the target objects (11), such that the target objects (11) can be differentiated from one another based on the identification code (ID). The measurement device (2) has a distance and angle measurement functionality for determining the position of the target objects (11) and at least one radiation source (21) for emitting an optical beam (22) in a defined spatial direction, in particular a pivotable, vertically expanded laser beam. A target unit (3) that represents one of the target objects (11) has a reflector (31), in particular an optical retro reflector, and a detector (32) for receiving the optical beam (22). According to the invention, the measurement device (2) is designed for emission of the beam (22) such that the identification code (ID) of a target object (11) that is searched for from the target object volume can be modulated to the beam (22) as a code (sID) to be searched for. The target unit (3) has an evaluation component (33) connected to the detector (32) for inspecting correspondence between the code (sID) modulated to the beam (22) and the own identification code (ID) of the target unit (3) and a transmission component (34) for transmission of a reactive confirmation signal (35) to the geodesic measurement device (2) that takes place upon correspondence being determined. Furthermore, according to the invention, a processing component (23) of the measurement device (2) is designed to identify the target unit (3) from the target object volume based on the reactive confirmation signal (35), in particular dependent on a receiving time of the reactive confirmation signal (35).
