Procedure for the measurement of heliostats. The present invention relates to a method for the measurement of heliostats (1) of a heliostat field of a central tower solar power plant having several heliostats (1). The heliostats (1) respectively have at least one reflector (3) which has a mirror surface (5) with the following steps: - positioning of an aircraft (9) controllable above the field of heliostats in a predetermined initial position (p), - movement of the aircraft (9) according to a predetermined flight pattern (15) and simultaneously taking images of a heliostat (1) or several heliostats by means of a camera (13) at a predetermined time interval, evaluating the images, - generation of at least one evaluation image of a reflection (11 ') of a target (11) formed by the aircraft (9) or a part of the aircraft (9) on the mirror surface (5) of the at least one reflector (3) of the heliostat (1) and determination of the position of the objective (11) with reference to the at least one reflector (3), - evaluation of the at least one evaluation image for the determination of at least one normal vector (n) of the mirror surface (5) by the position of the objective (11), determining the optical axis of the heliostat (1) through of the at least one normal vector (n) and/or determining the shape error of the mirror surface (5).
