Disclosed is a gimbal device for a helicam, including a camera balance control function of automatically setting a gravity center of a gimbal regardless of a kind of a camera. According to the present invention, the gimbal device for a helicam comprises: a first rotor directly connected to a helicam; a second rotor rotating in a Y-axis and arranged on one end of the first rotor; and a third rotor installed at the end of the second rotor and rotating in a Z-axis. The third rotor is a structure in which a camera is directly installed. The third rotor includes: each support connected to each end of the second rotor, wherein rotation thereof is controlled by a third servomotor; a stand horizontally installed on both ends of the support; an actuator mounted on the upper surface of the stand and changing an installation position of the camera; a gyro-sensor installed at an adjacent position of the actuator and indicating change in the gravity center of the third rotor; and a control device controlling transfer displacement of the actuator by corresponding to an output signal of the gyro-sensor. Therefore, the gimbal device for a helicam detects the change in the weight center, which occurs after the camera is mounted, in real time when a camera gimbal is installed. The gimbal device for a helicam accurately controls the actuator by corresponding to a detection result so rapidly resets the gravity center of the stand by the mounted camera. |
