Abstract
A geodetic measuring instrument for determining the position of a target point includes a sighting apparatus that can be pivoted with respect to a base of the measuring instrument to change the orientation of the sighting apparatus. The geodetic measuring instrument has at least one objective unit defining an optical target axis and has angle measurement functionality for precisely detecting the orientation of the target axis. Evaluating means store to and control the orientation of the sighting apparatus. An eye image recording unit records eye images of an eye of a user. The evaluating means perform automatic sighting functionality regardless of viewing direction in such a way that the following occurs automatically after the function has started: at least one eye image is recorded, a viewing direction of the user eye is determined, or eye information suitable for deriving a viewing direction of the user eye is determined.

16. A geodetic measuring appliance, for determining the position of a target point, comprising
a targeting device that is pivotable in a motorized manner relative to a base of the measuring appliance for the purpose of changing the alignment of said targeting device and has at least one objective unit that defines an optical target axis; -
angle measuring functionality for high-precision acquisition of the alignment of the target axis; an eye image acquisition device configured to acquire eye images of an eye of a user; and evaluation means for data storage and control of the alignment of the targeting device, the evaluation means being configured to implement an automatic viewing-direction-dependent targeting functionality in such a way that the following take place automatically after the function has started; at least one eye image is recorded; a viewing direction of the user'"'"'s eye or of eye information suitable for deriving a viewing direction of the user'"'"'s eye is determined by means of image processing on the basis of the at least one eye image; and the alignment of the targeting device is changed in a motorized manner depending on the viewing direction of the user'"'"'s eye or depending on the eye information. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for controlling a targeting device of a geodetic measuring appliance, wherein
acquiring eye images of a user'"'"'s eye are acquired, wherein the following take place automatically after the acquisition of the eye images begins: -
recording at least one eye image; determining a viewing direction of the user'"'"'s eye or of eye information suitable for deriving a viewing direction of the user'"'"'s eye by means of image processing on the basis of the at least one eye image, and changing the alignment of the targeting device depending on the viewing direction of the user'"'"'s eye or depending on the eye information. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
