Title
(EN) MEASURING DEVICE THAT CAN BE OPERATED WITHOUT CONTACT AND CONTROL METHOD FOR SUCH A MEASURING DEVICE
Abstract
(EN)
The invention relates to a geodetic measuring Instrument (1), in particular a theodolite or a total Station, fordetermining the Position of a target point, comprising a sighting apparatus (5), in particular a telescope, wherein the sightingapparatus (5) can be pivoted in a motorized manner with respect to a base ( 11) of the measuring Instrument (1) in order to change theorientation of the sighting apparatus and has at least one objective unit (21) that defines an optical target axis (6), angle measuremento functionality for detecting the orientation of the target axis (6) highly precisely, and evaluating means for storing data andControlling the orientation of the sighting apparatus (5), characterized by an eye image recording unit (4, 4"), which is designed torecord eye images of an eye (3) of a user, and characterized in that the evaluating means are designed to perform automatic sightingfunctionality regardless of viewing direction in such a way that the following occurs automatically after the function has started: atleast one eye image is recorded, a viewing direction of the user eye (3) is determined, or eye Information suitable for deriving aviewing direction of the user eye (3) is determined, by means of image processing on the basis of the at least one eye o image, and the orientation of the sighting device (5) is changed in a motorized manner according to the viewing direction of the user eye (3) oraccording to the eye Information.
