US Patent 11317025 Movie camera stabilization and control system

The invention relates to movie camera stabilization and control systems in an inertial space, based on classic four-axes gimbal structure, that comprises four frames which are successively connected to each other and have mutually perpendicular rotation axes. In proposed embodiment camera orientation is controlled by three inner gimbal's frames that are controlled by first control sub-system and the first gimbal frame is controlled by second control subsystem. Proposed control subsystems are simple in realization, independent from each other and together with four-axes gimbal provide unrestricted orientation control of the movie camera in inertial space regardless of the gimbal mounting point orientation.
