摘要： The invention relates to a technical stage device (1), comprising a fastening element (2), a bearing element (3) and a functional element (4), in particular a camera or a spotlight, wherein the functional element (4) is arranged on the bearing element (3) so as to be pivotable about a tilt axis (14) and wherein the bearing element (3) is arranged on the fastening element (2) so as to be rotatable about a pan axis (13), wherein a position determination arrangement is provided, which is designed in such a way that a relative movement between the bearing element (3) and the fastening element (2) as well as between the bearing element (3) and the functional element (4) can be determined. Further, the invention relates to a method for determining the correlation function of predetermined tilt and pan values of a functional value (4), in particular a camera or a spotlight, to absolute motion values of the functional element (4).

摘要： Method for calibrating a spotlight (1) which is rotatable about a pan axis (7) by entering pan values and pivotable about a tilt axis (8) by entering tilt values to absolute angle coordinates, wherein the spotlight creates an illuminated, preferably elliptical, area (5) on the ground (3) by means of a directed cone of light (4), wherein a light sensor (2) is placed on the ground (3), wherein the illuminated area (5) is moved across the ground (3) by rotating and pivoting the spotlight (1), wherein the light sensor (2) detects the edges of the illuminated area (5) and wherein a mapping assignment of the pan values and/or tilt values of the spotlight (1) to the angular coordinates of the spotlight (1) is determined by rotating and/or pivoting the spotlight (1) and by detecting the illuminated area (5) anew.
