Abstract: A computerised motion control apparatus for controlling a plurality of degrees of freedom of the positioning and orientation of a camera. The apparatus including a dolly (71) positionable by drive means along an extensible track arrangement (72), having a camera (73) mounted thereto and provided with motors to orientate the camera (73) by varying its pan (76), tilt (75), and roll (74). An operator interface device (15) is used to define position and velocity characteristics of the desired motion of each of the camera's axes of motion and a motor driver module (69) calculates a parametric cubic polynomial representation of the desired motion curve. The calculated coefficients of the motion curve parametric cubic polynomial representation are easily stored and used to regenerate the values of the curve for the purposes of display and providing motion curve values for each axis of motion of the camera. These calculations can be performed upon command and in real-time.
