  • Patent number: 9052585
    Abstract: To provide a control system of a stereo imaging device that is able to obtain a stereo image, which can be viewed stereoscopically, even when relative-position relationship of a pair of imaging units is unknown. A control system of a stereo imaging device includes a pair of imaging units, an error calculation unit and a control unit. A pair of the imaging units has a digital or analog degree of freedom so as to be able to control at least a yaw, pitch, roll and zoom factor, and can capture video frames using imaging elements. The error calculation unit uses each of images captured by a pair of the imaging units to calculate a rotating error and zoom error of each imaging unit on the basis of a difference from a predetermined standard convergence model of each imaging unit.

  • Patent number: 8788094
    Abstract: Provided is a cooperative control device capable of advanced cooperative control. The cooperative control device for cooperatively controlling a plurality of control objects is provided with a pair of output control systems, a pair of crossing circuits, and transfer function units. The pair of output control systems is provided for a pair of control objects having respective control circuits. The pair of crossing circuits is provided from a first input side to a second output side and from a second input side to a first output side of the control circuit of the output control systems. The transfer function unit is provided in each pair of crossing circuits.
