Storing and controlling movement path of film camera

摘要

The method for storing and controlling the movement sequence of a movie camera, controlled by a motor in height, angle and movement, is utilised in training an operator, where the desired movement sequence between start and endpoint is by a manual control. During the movement sequence a demand value for movement speed is set. From the first demand value by means of digital filtering and w.r.t. the motor power data and predetermined acceleration profiles a second value is calculated. The second value is stored and the motor is governed according to this value during the travel. Controller (20) for motor (M) and filter assembly (30-34) comprise the control assembly.
