Ground measurement method for accuracy of distance measurement sensor for rendezvous and docking of airships

The invention discloses a ground measurement method for accuracy of a distance measurement sensor for rendezvous and docking of airships. The coordinate system of a distance measurement sensor body is visibly derived by using an electronic theodolite measurement system, and a plurality of kinds of the coordinate systems are converted by combining a controlling field method. The coordinate system of the distance measurement sensor body and the coordinate system of the controlling field are unified by using a high-precision ground measurement control network. Distance measurement is performed on a reflection target of the distance measurement sensor by using a high-precision total station. The data of the plurality of kinds of the coordinate systems is integrated according to existing measurement data so as to deduce the relative distance between the distance sensor and a target marker; and the relative distance is compared with the actual measurement result of the distance measurement sensor so as to obtain the measurement accuracy of the distance measurement sensor finally.
