METHOD OF ACQUIRING HORIZONTAL DISTANCE BETWEEN CAMERA AND TARGET, AND CAMERA AND SURVEILLANCE SYSTEM ADOPTING THE METHOD |
摘要 |
Exemplary embodiments disclose a method of acquiring a horizontal distance between a camera and a target, which is a horizontal distance between a central point of an optical system of the camera and a ground landing point of the target. The method includes acquiring a relative target angle using an angle between a ground and a camera-target connection line which connects the central point of the optical system of the camera and the ground landing point of the target, acquiring a height of the camera using a height of the central point of the optical system of the camera on a basis of a vertical position of the ground landing point of the target, and setting a quotient of the height of the camera divided by a tangent value of the relative target angle as the horizontal distance between the camera and the target. |

1. A method of acquiring a horizontal distance between a camera and a target, which is a horizontal distance between a central point of an optical system of the camera and a ground landing point of the target, the method comprising:
acquiring a relative target angle using an angle between a ground and a camera-target connection line which connects the central point of the optical system of the camera and the ground landing point of the target; acquiring a height of the camera using a height of the central point of the optical system of the camera on a basis of a vertical position of the ground landing point of the target; and setting a quotient of the height of the camera divided by a tangent value of the relative target angle as the horizontal distance between the camera and the target.
