Method and Device For Moving a Camera Disposed on a Pan/Tilt Head Long a Given Trajectory
First Claim
1. Method for moving a camera (3) disposed on a pan/tilt head (5) along a defined trajectory (2), in particular on a set or in a studio (1),characterized in thatan associated trajectory for the spatial positions and orientations of a basic reference system (4) of the pan/tilt head (5) is determined from the defined trajectory (2) for the camera (3), and associated control variables for shafts (A1-A6) of a robot (8) movable in Cartesian coordinates, on whose receiving flange (7) the pan/tilt head (5) is attached, are generated from the determined trajectory of the basic reference system (4) of the pan/tilt head (5) and are transmitted to the shafts (A1-A6).

Abstract
The invention relates to a method for moving a camera that is disposed on a pan/tilt head along a given trajectory especially in a set or studio as well as an associated camera robot. In order to be able to move a camera with repeated accuracy along a given trajectory, an associated trajectory is determined for the spatial positions and orientations of a basic reference system of the pan/tilt head from the given trajectory for the camera, and associated control variables for shafts of a robot that can be moved in Cartesian coordinates are generated from the determined trajectory for the basic reference system of the pan/tilt head and are transmitted to the shafts, thus allowing camera movements to be made that are not possible with previously known systems.
