System and method for measuring FOV of imaging seeker

摘要

The present invention relates to a system and method for measuring the field of view (FOV) of a video explorer, in which a movement speed of the video explorer is determined to calculate the FOV of the video explorer while moving the video explorer at the determined movement speed. The system according to the present invention comprises: a movement control unit which moves a video explorer acquiring video for a fixed target; and an FOV calculation device which includes a first target position determination unit determining whether the fixed target appears in video acquired at a predetermined time interval by the moving video explorer, a first explorer position acquisition unit which acquires first position information of the video explorer when it is determined that the fixed target appears in the video, a second target position determination unit which determines whether the fixed target disappears from the video when the first position information is acquired, a second explorer position acquisition unit which acquires second position information of the video explorer when it is determined that the fixed target disappears from the video, and an FOV calculation unit which calculates the FOV of the video explorer on the basis of the first position information and second position information.
