Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a nighttime sighting apparatus and method for a toll-

The present invention relates to a night vision device and method for a tokuno, and more particularly to a night vision device and method for a tocunno applying a forehead angular movement aiming source.

It is an anti-aircraft weapon system that responds to enemy aircraft. First, distance information of the target is obtained through the radar. In the shooting control calculator, information for calculation of the leading angle is provided by using distance information and target specification. The leading angle is the angle direction toward the expected movement point ahead of the target moving direction, not the current target position. Since the speed of the enemy aircraft is fast, it is necessary to hit the enemy airplane in the direction of the leading direction.

In Gunpowon, this lead angle is charged, and the shooter keeps track of the target itself even after the lead charge. In the daytime, a line-counting sphygmomanometer is used to display the image. When the sphygmomanometer is driven in the opposite direction to the direction of the line, the target of the current position can be tracked.

In the nighttime, however, a stray light amplifying type night vision device (for example, KAN / TVS-5) is used instead of a lead calculation sight device. The stray light amplifying night vision device provides night vision to the shooter, And the enlargement ratio is narrowed to 5.6, so that the function is very limited and poor. Particularly, there is a problem that the moving target is very difficult to shoot at night because there is no tracking function after the leading charge.

It is an object of the present invention to provide a night vision device for a tocunno applying a leading angular movement aiming circle.

It is another object of the present invention to provide a nighttime sighting method for a tocano canal using a guided angular movement aiming circle.

Here, the lead angle calculation module may be configured to calculate using the look-up table that is provided in advance, which indicates the relationship between the high angle signal and the azimuth angle signal and the target distance and the lead angle. The aiming movement module may be configured to determine how many pixels to move the aiming circle in consideration of the number of pixels of the display module and the clock of the night vision device. And the aiming circle movement module may be configured to display the aiming circle at a position in the direction of the target of the edge of the display module when the target is out of the watch of the night vision device.

According to another aspect of the present invention, there is provided a nighttime boreal aiming method for a tofano using an angle-of-motion sighting source, the method comprising the steps of: receiving and displaying an infrared image from an infrared camera; receiving an elevation angle signal and azimuth angle signal of the target from the shooting control calculator; Calculating a target distance and a guidance angle using the received high angle signal and azimuth angle signal, moving the aim circle using the calculated target distance and the guidance angle in the displayed infrared image, And displaying the information to be displayed. The step of calculating the target distance and the guidance angle using the received high angle signal and the azimuth angle signal may further comprise the steps of calculating a distance between the high angle signal and the azimuth angle signal and a look- table). < / RTI > The step of moving the aiming circle by using the calculated target distance and the leading angle in the displayed infrared ray image and displaying the target ray so as to match the target may further include a step It can be configured to move and determine how many pixels the circle will move. And moving the aiming circle by using the calculated target distance and the leading angle in the displayed infrared image and displaying the target to coincide with the target when the target moves out of the watch of the night vision device, And to display the aiming circle at a position in the direction in which the target is located.

At this time, it may be configured to calculate using a look-up table that is provided in advance to show the relationship between the high angle signal and the azimuth angle signal and the target distance and the line angle. The relationship can be constituted by a proportional relationship.

The aiming circle moving module 130 may be configured to move the aiming circle by using the target distance and the leading angle calculated by the leading angle calculating module 120 from the infrared image displayed on the display module 110 and to display the target circle so as to match the target . At this time, the aiming movement module 130 may be configured to determine how many pixels to move the aiming circle in consideration of the number of pixels of the clock and the display module 110 of the night vision device 100 and to move.

The aiming movement module 130 may be configured to display the aiming circle at a position in the direction of the target of the display module 110 when the target is out of the watch of the night vision device 100. [ Thus, even if the target moves out of the clock due to a rapid movement of the target, the shooter can retrieve and track the target again.

FIG. 2 is a flowchart of a nighttime beaconing method for a tocanoe applying a line-of-sight moving-point source according to an embodiment of the present invention.

Receiving and displaying an infrared image from an infrared camera;

Referring to FIG. 2, the lead angle calculation module 120 receives the high angle signal and the azimuth angle signal of the target from the shooting control calculator 30 (S110).

Next, the lead angle calculation module 120 calculates the target distance and the lead angle using the previously received high angle signal and azimuth angle signal (S120). At this time, the lead angle calculation module 120 may be configured to calculate using a look-up table that is provided in advance to show the relationship between the high angle signal and the azimuth angle signal and the target distance and the lead angle.

Next, the aiming movement module 130 moves the aiming circle by using the target distance and the guidance angle calculated by the guidance angle calculation module 120 in the infrared image displayed on the display module 110, and displays the target circle so as to match the target (S130). At this time, considering the number of pixels of the clock and display module 110 of the night vision device 100, it may be configured to determine how many pixels to move the aiming circle and to move. On the other hand, if the target is out of the watch of the night vision device 100, it may be configured to display the aiming circle at a position in the direction of the target of the edge of the display module 110. Thus, even if the target is missed due to the narrowness of the clock, the target can be tracked again.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims There will be.
