  • Patent number: 9161020
    Abstract: The present invention provides a 3D video shooting control system which controls the position and direction of a pair of imaging devices in order to obtain a suitable 3D effect or maintain the safety, taking the shooting condition and the viewing condition into consideration comprehensively. A base-line length and a convergence angle of a pair of imaging devices are controlled based on an integration model in which a 3D shooting and broadcasting model and a 3D object model are integrated. A base-line length determination unit 6d-1 determines a base-line length based on the relationship expressed by an integration model equation 1 and a camera control unit 6e moves the pair of imaging devices to change the position thereof so that the pair of imaging devices has the determined base-line length.

  • 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.
