Operating device and method for remote control of arming device

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.

A method of remotely controlling an arming device comprising a range finder and an imaging device, performed by an operating device receiving a range measurement value measured by the range finder and an image captured by the imaging device, the method comprising:

• confirming a tracking image at each firing time point of a laser beam transmitted by the range finder;
• based on an image correlation value of a target locked on by a tracking gate in the tracking image exceeding a threshold value, determining that the target is normally locked on;
• determining 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
• based on the image correlation value exceeding the threshold value and the laser beam from the range finder hitting the target normally locked on, determining a range measurement value measured by the range finder as a true value of the target and determining other range measurement values as wrong measurement values based on the image correlation value being less than or equal to the threshold value,
• wherein, based on a first area of the laser beam hitting the target being greater than or equal to a first preset value, determining that the laser beam from the range finder is hitting the target normally locked on,
• wherein, based on a second area where the laser beam overlaps the tracking gate being greater than or equal to a second preset value, classifying and displaying the target as a range-measurable shape, and
• wherein, based on the second area where the laser beam overlaps the tracking gate being less than the second preset value, classifying and displaying the target as a range-immeasurable shape.
