Robotic television-camera dolly system

摘要

A robotic camera dolly system includes a motorized dolly which rolls freely across a studio floor under computer control, the dolly carrying a camera. Targets are provided on the floor at various locations from which camera shots are to be taken. The dolly is moved from one target to the vicinity of another target according to a learned sequence of movements controlled by a remote dolly computer. The learned sequence of movements is taught with the aid of a joystick, and the motions are replayed based on dead reckoning. In order to correct translational and angular errors in the position of the dolly at the destination target, optosensors are provided on the dolly for use in detecting and reorienting the dolly relative to the destination target. The open loop control of dolly movement can be taught with a control stick and the motions replayed based on dead reckoning.
