摘要

Some embodiments of the invention relate to a measuring device, in particular a video theodolite or video tachymeter. The measuring device may include a base, a support, a telescope optics having a lens, a physical target marking, an eyepiece, and a camera. The measuring device may also include an evaluation and control unit containing stored calibration parameters with respect to an image position indicating the target direction as target image position in the captured image, and a display for displaying a captured image having marking for the target image position. In some embodiments, a function may be included to respect and/or restore. In some embodiments, the function may be in form of an application on the user-device interface that can be called up.
