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.

摘要： A camera platform may be stabilized by reducing or avoiding oscillating movement, when active stabilization systems are not used. A passive dampener resists the back driving of the motors used in the active stabilization system. This dampening or resistance to back driving the motors in turn dampens movement of the camera platform. Oscillations are reduced or avoided and the camera platform may return more quickly and smoothly to a level position. The dampener may be provided as an add-on or temporarily electrically switched in accessory. The dampener may include a circuit that connects the first and second motors of the active stabilization system in series, and connects the series output of the two motors to a variable resistor through a rectifier. A transistor may be with the variable resistor to provide for more linear adjusting and a more compact variable resistor.

摘要： A camera crane carrier includes a vehicle having a front end and a back end. A front elevator is movable vertically between up and down positions, at a forward position on a deck vehicle. A back elevator is movable vertically between up and down positions, at a rearward position, below the deck. A ramp may be provided on the vehicle, with the ramp extendible from the deck at the back end of the vehicle to the ground. The elevators allow a camera crane to be more easily loaded onto the vehicle, and also allow lowering the center of gravity of the loaded vehicle. The vehicle may optionally be used as a camera car when not carrying a camera crane.

摘要： A camera crane includes a telescopically extendible arm with a camera platform pivotally attached to the front end of the arm. An arm support can support a back section of the arm at two or more positions. Consequently the pivot axis of the arm can be shifted to the front or rear, to change rear clearance requirements, counterweight requirements, and the reach of the arm. A leveling system on a nose assembly includes at least one motor within a sealed motor housing. When the head moves to an out of level position, an electronic controller energizes the motor which exerts torque to return the head to level.

摘要： A camera support or head has a pan frame pivotably attached to a support hub. The support hub is attached to a camera crane or similar apparatus. The pan frame has first and second spaced apart and parallel adjustable length pan arms. A pan motor is attached to the pan frame and adapted to pivot the pan frame about a pan axis relative to the support hub. A tilt frame is pivotably attached to the pan frame. The tilt frame may include first and second spaced apart and parallel adjustable length tilt arms attached to opposite ends of a camera mounting plate. A tilt motor is attached to the tilt frame and to the pan frame and is adapted to pivot the tilt frame about a tilt axis perpendicular to the pan axis. The adjustable length tilt arms allow the camera head to extended to accommodate cameras requiring more vertical clearance. The adjustable length tilt arms allow the camera platform to be moved to better locate the center of gravity of the camera on the tilt axis, for more balanced loading.

摘要： A stabilized camera system has a roll frame formed as a parallelogram linkage and pivotably attached to a pan frame. A tilt frame is pivotably attached to the roll frame. Control circuits are provided to compensate for drift, to allow manual aiming of the camera during stabilized camera operation, and for providing rapid leveling. The stabilized camera system is compact with low moments of inertia to allow rapid movements.

摘要： A camera crane mobile base has a drive motor assembly at each corner of a chassis. The drive motor assemblies may have an electric motor linked to an axle via gearing, and one or more wheels attached to the axle. The electric motors may be separately controlled to propel and steer the mobile base. A column is pivotally attached to the chassis and pivotal in lateral and longitudinal directions via actuators. The drive motor assemblies may be removed from the chassis for storage or transport. With the drive motor assemblies installed, the mobile base is highly stable and maneuverable. With the drive motor assemblies removed, the chassis is narrow enough to fit through a typical doorway. Steering systems may be linked to the drive motor assemblies at the front and/or rear of the chassis, to allow steering control of the mobile base in corrective, crab and/or round steering modes. The chassis may optionally have an upward curvature from either end towards the center location.
