Dual loop camera stabilization systems and methods

摘要

A method for stabilizing a camera platform includes generating a first signal from a platform sensor, such as a gyro sensor, on the camera platform indicative of a change in angular position of the camera platform. The first signal is added to a control signal provided from a camera platform position controller, typically operated by the camera operator. A first correction value based on the sum of the first signal and the control signal is calculated. A second correction value is calculated based on a signal from an encoder associated with a motor linked to the camera platform. Adding the first correction value and the second correction value provides a motor control signal which is amplified and used to control the motor.
