1 is a system diagram showing a simulation system for a bombardment training according to an embodiment of the present invention.

Referring to FIG. 1, a simulation system for an artillery training according to an embodiment of the present invention may include a screen 10, a simulation server 100, an image projection apparatus 50, and a simulation binoculars 200.

Specifically, the screen 10 can display the feature art images transmitted from the simulation server 100. [ At this time, the feature image may include an image related to the terrain such as a position where the user (or a trainee) is bombarded. The landmark image may be an actual photographed image or a virtual image.

The screen 10 may be provided with at least four indicia 20. In the embodiment of the present invention, five screens may be provided at the top, five at the center, and five at the bottom so that the screen 10 can be divided into three areas. The marking 20 may be a grid-like marking of a specific color so that the marking can be easily recognized by the user.

In the embodiment of the present invention, the screen 10 is provided with markers, but the present invention is not limited thereto, and markers may be displayed on the feature image.

The image projection apparatus 50 projects the feature art images received from the simulation server 100 on the screen 10. A normal projector or the like can be used as the image projection apparatus 50. [

The simulation server 100 stores a plurality of feature art images and transmits the selected feature art images to the image projection apparatus 50 according to the administrator's selection. The simulation server 100 may select a target image from the same geographical feature image that is supplied to the image projection apparatus 50 and transmit the selected target image to the simulation binoculars 200. The selection of the target image will be described later.

The simulation server 100 may receive the current position and attitude information of the simulation binoculars 200 and generate a target image. That is, the simulation server 100 may extract the target image to be displayed in the simulation binoculars 200 and transmit the target image.

For this purpose, the simulation server 100 may include a functional unit such as a storage unit (not shown) and an image extracting unit (not shown).

At this time, the target binoculars 200 may display different target images at various positions on the front side of the screen 10. That is, they are observed differently from the viewpoint of users at different positions with respect to the same area. In order to transmit such a point to the target image of the simulation binoculars 200, the simulation server 100 must transmit a different target image for each point of view of the selected region through the position and attitude information of the simulation binoculars 200. [

For example, the simulation server 100 may transmit a target image with different viewpoints to the simulation binoculars 200, respectively, when observing the region A shown in Fig. 4 at position 1 and observing at position 2, respectively.

The simulation binoculars 200 display a target image, enlarge it, and allow the user (a trainee) to recognize it. In addition, the simulation binoculars 200 transmit the current position and attitude information to the simulation server 100.

That is, in the present invention, the feature art image projected on the screen 10 is an image that can be visually recognized, and the simulation binoculars 200 can enlarge a certain area of the feature art image and display it to a user.

In particular, the simulated binoculars 200 and the simulation server 100 perform real-time communication to generate and display a target image. At this time, the simulation server 100 and the simulation binoculars 200 use a 1-channel HDMI image transmission method.

The simulation binoculars 200 are equipped with a sensing means for measuring the current position and posture, provided with a display means capable of displaying a target image, and can be provided with a lens for enlarging the target image. A specific description of the simulation binoculars 200 will be described with reference to FIGS. 2 to 4. FIG.

FIG. 2 is an exploded perspective view showing the simulation binoculars shown in FIG. 1, and FIG. 3 is a cross-sectional view showing a cross section of the simulation binoculars shown in FIG.

2 and 3, the simulation binoculars 200 include a body case 210, a display unit 240, a lens unit 250, a latch 220, a signal processing unit 270, a button 280, And a sensor unit 230.

Specifically, the body case 210 is an outer shape of the simulation binoculars 200 equipped with an eyepiece 260 that is in close contact with the user's eyes, and is formed to have the same shape and weight as those of the actually used military binoculars. The body case 210 is provided with a space in which the display unit 240, the lens unit 250, and the sensor unit 230 are installed.

The lens unit 250 enlarges the target image displayed on the display unit 240 and allows the user to recognize the target image. To this end, the relay unit 250 and the eyepiece lens assembly 257 are disposed in series in the lens unit 250. At this time, a pair of lens units 250 are provided in each of the left and right eyes.

The relay lens assembly 255 is installed close to the display unit 240. The relay lens assembly 255 may be a combination of a convex lens, a concave lens, a telecentric lens, an achromatic doublet lens, or the like.

The eyepiece assembly 257 is formed between the eyepiece 260 and the relay lens assembly 255. The eyepiece assembly 257 has a plurality of lenses arranged so that an image through the relay lens assembly 255 adjusts the distance.

The ocular lens assembly 257 may be formed by combining convex lenses, flat convex lenses, concave lenses, and the like. For example, the eyepiece assembly 257 may be a Ramsten eyepiece consisting of two flat convex lenses, or may be a Kellner eyepiece, a compensating eyepiece, or the like.

The signal processing unit 270 provides the image provided by the simulation server 100 to the display unit 240 and provides the current position and orientation information measured by the sensor unit 230 to the simulation server 100. The signal processing unit 270 includes a communication module and can transmit signals to the simulation server 100 through the TCP / IP communication method.

The display unit 240 is provided on the opposite side of the eyepiece unit 260. The display unit 240 is mounted inside the body case 210 and can be protected from an external impact. The display unit 240 may be provided with two display elements 242 and 244 corresponding to the left and right eyes. The display unit 240 may be a display device such as an LCD or OLED to display the target image provided by the simulation server 100. At this time, since the display unit 240 is disposed at the end of the lens unit 250, it is preferable that the display unit 240 is formed in a small size to allow the user to view the image on the lens unit 250.

At least one of the two display elements 242 and 244 of the display unit 240 can be shifted from the center. For example, the first display element 242 provided on the left eye side is disposed in the center of the left eye lens unit 250, and the second display element 244 provided on the right eye side is disposed on the right eye side. And may be shifted to the right or left in the center of the unit 250. Accordingly, the target image transmitted to the display unit 240 can be recognized in three dimensions.

At this time, the second display element 244 is positioned in the center of the lens unit 250 on the right eye side, and the first display element 242 is shifted to the left or right side in the center of the left lens unit 250 It is possible.

According to the embodiment of the present invention, in order to allow the target image to be recognized as three-dimensional by the user, it is possible to provide a shifted target image to any one of the first and second display elements 242 and 244 have. For example, the first display element 242 is provided with a target image, and the second display element 244 is provided with a shifted target image. Thus, the target image can be recognized in three dimensions. In contrast to the above description, only the first display element 242 is provided with a shifted target image so that the target image can be recognized in three dimensions.

Here, the first and second display devices 242 and 244 can receive the same target image from the simulation server 100 through a single-channel HDMI.

The sensor unit 230 may provide the location of the simulation binoculars 200 to the simulation server 100. The sensor unit 230 recognizes at least four landmarks on the screen 10 and transmits the current position and attitude information to the simulation server 100.

To this end, the sensor unit 230 may include at least one of a gyro sensor, an acceleration sensor, and a geomagnetic sensor.

Hereinafter, the operation of the sensor unit 230 will be described with reference to FIGS. 4 and 5. FIG.

4 and 5 are views for explaining the measurement of the current position and attitude information in the sensor unit.

4 and 5, the sensor unit 230 recognizes the four markings provided on the screen 10 to measure the current position and attitude information of the simulation binoculars 200. As shown in FIG. At this time, the four markers form a rectangle.

First, when the first mark 20a is depressed and the button 280 provided in the simulation binoculars 200 is pressed, it is recognized as the first coordinate (0, 0). Thereafter, when the second mark 20b is clamped and the button 280 is depressed, the movement distance between the first mark 20a and the second mark 20b is calculated and set to the second coordinate (0, x) . The third landmark 20c is also recognized as the third coordinate y (0) by calculating the travel distance from the second landmark 20b. The fourth landmark 20d is also calculated by calculating the travel distance from the third landmark 20c And recognizes it as the fourth coordinate (y, x).

At this time, the coordinate recognition can use the angle and the acceleration in the gyro sensor or the acceleration sensor. That is, the distance between the two markers 20a and 20b is calculated by measuring the acceleration moving between the first marker 20a and the second marker 20b, and the distance between the two marks 20a and 20b It is recognized as plane coordinates. For example, the coordinates of the first landmark 20a are set to (0,0), and the coordinates of the second landmark 20b are set to (0, x).

Then, the distance between the two marks is calculated by measuring the acceleration moving between the second mark 20b and the third mark 20c, and then the coordinates of the third mark 20c are set to (x, y) . Next, the acceleration between the third marker 20c and the fourth marker 20d is measured to calculate the distance between the two marks, and then the coordinates of the fourth marker 20d are set to (y, 0) .

At this time, a first angle? Moving from the first marking 20a to the second marking 20b and a second angle? Moving from the second marking 20b to the third marking 20c are measured The posture information can be set.

The four coordinate information and the first and second angles are transmitted to the simulation server 100.

The simulation server 100 sets the region of the target image through the received four coordinate information. Also, the simulation server 100 sets attitude information through the first and second angles? And?.

5, the simulation server 100 receives the coordinate information of the area 1 and the first and second angles? 1 and? 1 in the simulation binoculars 200a at position 1, ).

The simulation server 100 receives the coordinate information of the first area and the first and second angles? 2 and? 2 in the simulation binoculars 200b at the position 2 to thereby obtain the position of the simulation binoculars 200 at the position 2 Backward.

In this case, it is preferable that the target images of the position 1 and the position 2 are the same but the positions of the target image of the position 1 and the position 2 are generated differently.

That is, the simulation server 100 provides the target image set with the obstacle or facade front in the direction observed by the simulation binoculars 200a at position 1, and the side of the obstacle or facility with the simulation binoculars 200b at the position 2 And provides the set target image. Accordingly, the simulation server 100 can generate the target image differently according to the position of the simulation binoculars 200, and transmit the target image so that the training is perceived as a real situation.

That is, since the shell coordinates for the same object are different for each position of the simulation binoculars, it is possible to improve the accuracy of the shell training by providing such an environment.

The sensor unit 230 recognizes the four markers provided on the screen 10 to measure the current position and attitude information of the simulated binoculars 200. The sensor unit 230 displays four markers located at the corners of the screen 10, Can be recognized.

In this case, the present position and attitude information of the binoculars 200 can be measured by the above-described mechanism, and the edge of the screen 10 can be recognized by the simulation server 100.

In this case, the simulation server 100 can give an alarm to the binoculars 200 when it is determined that the binoculars 200 are moving in the direction away from the screen 10 through the attitude information of the binoculars 200, The binoculars 200 can be adjusted so as to face the screen 10.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
