Method and apparatus for stabilizing payloads, including airborne cameras

摘要

Methods and apparatuses for stabilizing payloads, including airborne cameras, are disclosed. In one embodiment, the apparatus employs a gimbal system in which the camera is mounted, together with suitable motors for pointing the camera by actuating this gimbal system and suitable sensors for deriving a signal to drive these gimbal motors. The gimbal axes can be arranged in a sequence that can provide for camera stabilization while reducing complexity, avoiding gimbal lock, increasing redundancy and enhancing performance.
