A camera mounting for a TV/video camera, comprising a base (11) having a datum point, and a counter-balanced arm assembly (10) mounted on the base at one end (15) thereof and having a platform (21) for carrying a camera at the other end thereof for supporting the camera platform for movement in three orthogonal axes with respect to the datum. Transducer means (35, 36, 37) are provided for determining movement of the camera platform with respect to the datum point in said three axes to provide information regarding the location of the camera for purposes such as controlling movement of a virtual reality image to be combined with a real image as seen by the camera as the camera is moved with respect to the datum. The transducers may be provided on the hinge points (Fig 4) or follow movement of a carriage 32 and a pin 34 provided on the boom arm 16 and moving in a slot 33 on the carriage 32. |
