A measuring system comprising a measuring instrument and a computer system, the measuring instrument comprising - a base unit configured for positioning the measuring instrument, - a support unit mounted on the base unit and configured for being horizontally rotatable relative to the base unit, - a targeting unit comprising a distance meter, the targeting unit being mounted on the support unit and configured for being vertically rotatable relative to the support unit, the distance meter having a targeting axis, - a first angle encoder configured for measuring a horizontal angular position of the support unit, - a second angle encoder configured for measuring a vertical angular position of the targeting unit, - a camera with a field of view that is crossed by the targeting axis, wherein the camera is configured for capturing image data, wherein the camera is an Automatic Target Recognition camera (ATR-camera) which has a sensor designed to detect flash light (ATR-light), the ATR-camera being comprised by an Automatic Target Recognition system (ATR-system) designed for emitting the ATR-light, the ATR-system being integrated in the measuring instrument, - a control unit configured for computing a position of a target based on a preconfigured target attribute, the computer system being configured for - receiving the image data from the camera, - executing a classifier, the classifier being configured for determining at least one of a plurality of classes based on classifying at least part of the image data, wherein each of the plurality of classes is associated with a class target attribute, - validating the preconfigured target attribute based on the at least one class target attribute which the determined at least one of the plurality of classes is associated with, - generating result data based on the validation, and - providing the result data. the measuring instrument comprising - a base unit configured for positioning the measuring instrument, - a support unit mounted on the base unit and configured for being horizontally rotatable relative to the base unit, -
