Assignee: HANWHA AEROSPACE CO., LTD.
Field: Other special machines (Mechanical engineering)
Classification: CPC F  G | IPC F  G

Claim 3:
4. An operating device configured to remotely control an arming device comprising a range finder and an imaging device, the operating device comprising a processor configured to:
confirm a tracking image at each firing time point of a laser beam transmitted by the range finder;
determine that a target is normally locked on based on an image correlation value of the target locked on by a tracking gate in the tracking image exceeding a threshold value;
determine whether the laser beam from the range finder hits the target determined as being normally locked on based on a center value of the tracking image and a center value of the tracking gate; and
determine a range measurement value measured by the range finder as a true value of the target and determine other range measurement values as wrong measurement values based on the laser beam from the range finder hitting the target normally locked on,
wherein the processor is further configured to:
manually or automatically adjust a size of the tracking gate to a size of the target in the tracking image received from the imaging device, and
based on the range finder continuously measuring the range measurement value, control the size of the tracking gate to automatically adjust on the basis of a field of view of the imaging device, horizontal and vertical resolutions of an image sensor used in the imaging device, and horizontal and vertical pixel numbers of the tracking gate.
