ROBOTIC SURVEYING INSTRUMENT AND METHOD FOR THE AUTOMATED AUTOCOLLIMATION OF A TELESCOPE OF A SURVEYING INSTRUMENT COMPRISING AN AUTOCOLLIMATION TARGET

摘要

The invention relates to a method for automated autocollimation as an alignment of a telescope of a surveying instrument the telescope defining an optical axis such that the optical axis is perpendicular to a reflective surface of an autocollimation target in particular a coated plane mirror. The method comprises the following steps: a) aligning the telescope with the autocollimation target; b) illuminating a reticle in the telescope; c) focusing the telescope on infinite; d) acquiring the autocollimation target and the illuminated reticle (1) reflected by the reflective surface or the illuminated reticle by means of an image acquisition device arranged in the telescope or a second telescope; e) determining the reticle center in the image; f) determining the horizontal distance (?px) and the vertical distance (?py) of the reticle center from the optical axis of the telescope in the image; and g) converting the horizontal (?px) and vertical (?py) distances of the reticle center into a horizontal aberration angle (?H) and a vertical aberration angle (?V) of the current alignment of the telescope from the autocollimation alignment of the telescope.
