Since surveying instruments and measuring devices are used in greatly varying setups, stationings, and device locations or are also pivoted in the scope of the surveying, the elements in the surveying instrument are to be as gravitation-independent as possible, so as to avoid an additional gravit...
The present invention relates to a method for calibrating a surveying instrument comprising a camera, means for carrying out the method and surveying instruments calibrated by use of the method. Surveying often includes determination of angles or of positions of points, e.g. reflectors (triple refl...
