A method and a system for determining a 6-DOF-pose of an object in space use at least one marker attached to the object and a plurality of cameras. Perspectives of the cameras are directed to a common measuring space in which the object is positioned. At least one camera from the plurality of cameras is movable such that the movable camera can be adjusted with respect to the object. At least one of the cameras captures an image of said marker attached to the object. Based on the at least one captured image, spatial parameters representing the 3D-position or the 6-DOF-pose of the marker and, consequently, the 6-DOF-pose of the object in space can be determined.
