Motion control system for cinematography

摘要: A computerised motion control apparatus for controlling a plurality of degrees freedom the positioning and orientation camera. The including dolly (71) positionable by drive means along an extensible track arrangement (72), having camera (73) mounted thereto provided with motors to orientate varying its pan (76), tilt (75), roll (74). An operator interface device (15) is used define position velocity characteristics desired each camera's axes motor driver module (69) calculates parametric cubic polynomial representation curve. calculated coefficients curve are easily stored regenerate values purposes display providing axis These calculations can be performed upon command in real-time. Motion may modified way redefining parameters generated generator (50 ) digitally processed signal processing (57). variety functions generated, summation, filtering multiplication. Digital representative random, periodic aperiodic signals combined curves generated. Additionally, such as focus, film pull-down rates, shutter speed, etc. recorded reproduction synchronism replay motion. provision described facilities, enables accurate repeatability scene recording digital image integration real-life recordings, multiple time scale techniques special effects.
