Description

[0001] Apparatus for simulation target training [0002]

The present invention relates to a target acquisition simulation apparatus, and to an apparatus for simulating a virtual target acquisition training.

German Patent Publication No. 2008023955B4 describes a method and a simulation system for simulating events and processes of air vehicles, land vehicles, or vessels. This invention is based on the objective of operating the simulation device in real time, and the latency time caused by the data manager must be compensated, although the data required for operation are only available by the non-real-time simulation program .

In addition, International Patent Publication No. 96 / 26512A (corresponding translation of European patent - available DE696 23410T2) discloses a flight simulation based on the problem of more precisely simulating the actual movement sensed by the pilot when the flight is started.

As described above, conventionally, a simulation related to a flight is posted when a flight is operated, but a target acquisition simulation is not presented.

In the case of armed helicopters such as the Apache helicopter, the Target Acquisition & Designation System (TADS) is equipped with a sophisticated sensor to enable accurate target search and target acquisition with target aiming. For example, according to the manipulation of the control gun, the target is searched and the target is fired.

However, utilizing this Target Acquisition System (TADS) to practice target acquisition training is subject to spatial, temporal, and cost constraints. Therefore, it is necessary to develop a target acquisition simulation that can perform virtual target acquisition training to overcome these limitations.

Korean Patent Publication No. 10-2013-0045918

The technical problem of the present invention is to perform the target acquisition training without starting the air vehicle. In addition, it is possible to confirm target acquisition related data without activating the TADS equipment without activating the flying object.

An embodiment of the present invention is a battle scenario database storing topographic information data and positions of virtual targets for each battle mission. A terrain image generating unit for generating a terrain image from the terrain information data in the battle scenario database; A target training image generation unit for generating a plurality of virtual targets having positions of virtual targets in the battle scenario database and inserting the virtual targets into the terrain image to generate a target training image; A target training image display unit for displaying the generated target training image; A virtual target detecting unit for displaying a target training image positioned in a direction in which the optical bench faces in the target training image display unit and determining a position coordinate of a detected virtual target as a virtual target to be attacked; A virtual arming selection unit for selecting a virtual arming and a virtual launch condition to attack the detected virtual target; A virtual weapon launching unit for virtually launching a virtual weapon as the virtual launch condition for the detected virtual target; And a virtual target hit determination unit for determining whether the virtual target is hit success according to the selected virtual weapon and the virtual launch condition and notifying the result.

The virtual target detection unit may include: an optical bench; An optical disc regulator for performing a moving operation of the optical disc to control a directivity angle of the optical disc; An inertia measuring unit which is provided on the optical bench and detects inertia information including a steering angle of the optical bench according to a movement operation of the optical bench; A target training image selection module for displaying a target training image in a direction in which a steering angle of the optical bench is directed to the target training image display; And a virtual target position extraction module for extracting a positional coordinate of a detected virtual target selected after the virtual target to be attacked is selected from the virtual targets in the target training image in the direction of the direction of the optical band.

The virtual target position extraction module calculates the position coordinates of the detected virtual target using the compound navigation information according to the virtual flight of the virtual air vehicle and the inertia information measured by the inertia measuring device.

The composite navigation information is GPS navigation information generated by virtual navigation of a virtual flight vehicle.

And a virtual target distance calculating unit for calculating a distance of the detected virtual target detected.

The target training image display unit is implemented as a multifunctional display unit (MFD) and a helmet display unit (HMD).

According to the embodiment of the present invention, the TADS related function can be confirmed by utilizing the target acquisition simulation apparatus without using the actual TADS equipment in the state where the air vehicle is not activated in the target acquisition training.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

1 is a diagram showing a configuration of a target acquisition simulation apparatus according to an embodiment of the present invention.

Hereinafter, the target acquisition training means to detect and determine a virtual target to be attacked, and to execute a virtual target's hit training by launching a virtual weapon against the detected virtual target.

The target acquisition simulation apparatus 100 of the armed vehicle includes a combat scenario database 110, a terrain image generating unit 120, a virtual target generating unit, a target training image displaying unit 140, a virtual target detecting unit 150, A virtual weapon launching unit 170, and a virtual target hit determining unit 180. The virtual weapon launching unit 170 and the virtual target hit determining unit 180 are the same as those of FIG.

The battle scenario database 110 stores the location of the terrain information data and the virtual target for each combat mission. It stores terrain information data such as marine, mountain, and plains according to the combat mission, and also stores the location information of the virtual target. For example, in the case of mountain battles, position coordinates of virtual targets are placed in the mountainous region.

The terrain image generation unit 120 generates a terrain image capable of performing virtual target acquisition simulation. That is, the terrain image is generated from the terrain information data in the battle scenario database 110. The terrain image can utilize various terrain information data, for example, DTED (Digital Terrain Elevation Data), which is terrain information data. DTED is data with high or low information of terrain, and has terrain information by level. For example, in level 2, high and low data are stored in units of 1 arc second, and level 2 is 3 acr second. Therefore, the terrain information can be generated by using the DTED of the area to be simulated.

The target training image generating unit 130 generates a plurality of virtual targets having positions of virtual targets in the battle scenario database 110 and inserts the generated virtual targets into the terrain image to generate a target training image. Describing creating a virtual target, a virtual target having a location of a virtual target in the battle scenario database 110 is generated. The virtual target generates various virtual targets according to the virtual target positions of longitude, latitude and altitude. For example, various virtual enemy helicopters, enemy armored vehicles, enemy ships, etc. are created at virtual target locations of longitude, latitude and altitude. These virtual targets can be generated by training scenarios.

In addition, the target training image generation unit 130 inserts the generated virtual target into each position in the terrain image, inserts the position of the virtual armed vehicle into the terrain image, and generates the target training image. The location of the virtual armed aircraft can be located at the center of the terrain image. The target training image generation unit 130 inserts a virtual target into the terrain image generated from the DTED, and inserts a virtual target at the virtual target position. In addition, the target training image generating unit 130 generates a target training image by inserting the position of the virtual armed vehicle into the terrain image in which the virtual target position is displayed. Here, a virtual armed vehicle refers to a virtual flight vehicle in which a trainer is virtually mounted and operated. The position of the virtual armed aircraft is determined by a preset battle scenario. In addition, the position of the virtual armed aircraft can be reflected and changed by the manipulation of the trainee 's virtual armed aircraft. For reference, the terrain image and the target training image are displayed in three dimensions, thereby maximizing the stereoscopic effect and enhancing the training effect.

The target training image display unit 140 displays the generated target training image. The target training image display unit 140 may be implemented with a multifunctional presentation display unit (MFD) and a helmet sight display unit (HMD).

For reference, a multifunction display (MFD) is a display screen device disposed in front of a cockpit in an armed aircraft, and a multifunctional display unit (MFD) mainly includes an inorganic system management function, inorganic loading information, . Also, a head mount display (HMD) is a system that is mounted on a helmet of a pilot to provide information. In other words, it refers to the helmet control system by the concept of interfacing with the helmet and performing the battle by connecting with the sight of the battle situation. Further, all the flight information is integrated and managed on the display of the helmet, and the latest helmet control system interlocked with various mounted weapons can be applied.

The virtual arming selection unit 160 selects a virtual arming and a virtual launch condition from the trainee to destroy the virtual target selected by the trainee (hereinafter, referred to as a 'detected virtual target'). For example, if a detection target virtual target to be destroyed is an armored vehicle, a first missile capable of destroying a sturgeon is selected, and if the virtual target to be destroyed is a ground building, then the second missile capable of destroying concrete is a virtual weapon . ≪ / RTI > In addition, the virtual launch condition can set the distance between the detected virtual target and the virtual armed aviator position when the virtual weapon is fired for the detected virtual target, or can set the firing target angle when the virtual armed aviator fires, Or the angle of inclination of the virtual armed helicopter, which is a virtual armed aircraft, or the altitude of the virtual armed aircraft at the time of the virtual launch. In addition, virtual launch conditions such as the speed of the virtual armed aviator at the time of virtual launch toward the detected virtual target and the number of virtual launches may be included. On the other hand, when the virtual weapon is selected, a virtual weapon can be displayed on the helmet display portion of the head mount display (HMD) so that the trainee can select the virtual weapon.

The virtual weapon launcher 170 virtually launches virtual weapon as the virtual launch condition for the detected virtual target.

Generally, when an attack is actually made, the attacker gets a virtual target to attack from the pilot. The lockon determines the virtual target to attack. For example, when a pilot locks a specific target by pressing a trigger among the targets, a laser pointer provided outside the armed vehicle starts to track the locked target along the target from this time. The armed flight computer calculates the optimal path of the missile in conjunction with the GIS (Geographic Information System), and signals that it is possible to fire when the calculation is completed (about 1-2 seconds). Once the pilot confirms this signal, he will approve the launch by pressing the trigger again, and the missile will fly along the calculated route and hit the target.

The simulated arming launch unit 170 according to the embodiment of the present invention simulates that the armed selected for the detected virtual target is fired virtual when the detected virtual target is turned on by the choice of the trainee. At this time, according to the selected virtual launch condition, the traveling direction and the traveling speed of the virtual arming are simulated.

The virtual target hit determiner 180 determines whether the virtual enemy is successfully destroyed based on the selected virtual weapon and the virtual launch condition, and notifies the trainee and the external training management center. It is determined whether or not the virtual weapon hits the virtual target in accordance with the virtual launch condition. Depending on the virtual launch condition, the hit to the detected virtual target can be determined. For example, if the firing is virtually fired at an altitude firing condition that is too low than the normal altitude, it can be determined that the firing has failed. Detection based on hit or not It informs the trainee and the outside training management center whether the hit is successful for the virtual target.

The notification of success or failure of the virtual target is generated by generating an image of whether the detected virtual target is a complete, half wave, or destructive failure when the shot is fired in accordance with the selected virtual weapon and the virtual launch condition and displays it on the target training image display unit 140 . For example, if the aiming angle at the time of the virtual launch is set to hit the detected virtual target, then it indicates that the target has become full, or if the aiming angle at the time of the virtual launch is set to be partially hit on the detected virtual target In this case, it indicates that the detection target is a half wave of the detected virtual target, or if the aim angle at the virtual launch is set to deviate from the virtual target, the detected virtual target may be missed to indicate that the destruction of the detected virtual target has failed.

2, in order to acquire the positional coordinates of an actual target, it is necessary to mount the optical bench 10 (camera 10) on which the camera is installed, in order to actually acquire the position coordinates of the actual target ) Should be corrected.

As shown in FIG. 3, an optical bench is generally referred to as an 'optical bench' and a 'bench' in practice in order to conveniently perform optical measurement. The optical bench 10 is a rail made of a long and precise linear steel, and a light source such as a camera, a collimator, a lens, a sample table, and optical parts such as a microscope are fixed And the optical system can be adjusted while keeping the optical axis straight. That is, the optical bench 10 refers to a rail 10a having a scale for arranging optical measurement on a straight line of a light source, a sample, a lens or the like. An attaching device capable of sliding in close contact with the rail 10a is provided so that the elements can be freely exchanged. The precision can be two rails.

In order for a pilot to actually ride on a vehicle such as an armed helicopter to observe the targets, the orientation angle of the optical bench 10 with the camera 11 must be adjusted. Here, the directivity angle of the optical bench 10 refers to an inclined angle with respect to the longitudinal axis of the optical bench 10 and a direction to which the optical axis 10 is directed.

In order to direct the directing angle of the optical bench 10 toward the target, the angle of the attitude of the airplane should be corrected with reference to the mounting surface of the optical bench 10 mounted on the armed helicopter as shown in FIG. Therefore, in order to display the target image on the display unit according to the orientation angle of the optical bench 10, the airborne posture information must be corrected.

However, the target acquisition simulation apparatus 100 according to the embodiment of the present invention does not need the aviation posture information because it performs virtual target acquisition simulation without actually operating the aviation. And does not require a camera of the optical bench 10 for observing an actual target. Therefore, the virtual target detection unit 150 of the target acquisition simulation of the present invention can detect the optical bench 10 in the target training image display unit 140 in accordance with the movement operation of the optical bench 10 of the simulation trainee And the positional coordinates of the detected virtual target are determined by selecting the detected virtual target as a virtual target to be destroyed. 4, the inertia measuring device 12 is provided on the optical bench 10, and the inertia measuring device 12 is also moved along with the movement of the optical bench 10 according to the operation of the trainee of the target acquisition simulation By the movement, the inertia information according to the motion of the optical bench 10 is acquired, so that the direction of the steering angle to which the optical bench 10 is directed can be known.

To this end, the virtual target detection unit 150 displays virtual targets located in the direction of the optical axis 10 in the target training image display unit 140 according to the movement operation of the optical bench 10, The target is selected to determine the location coordinates of the selected detected virtual target.

5, the virtual target detection unit 150 includes an optical bench 10, an optical bench controller 151, a target training image selection module 152, an inertial measurement unit 12, a virtual target position extraction module 153 ).

The optical bench 10 is a rail 10a on which an inertia measuring instrument is disposed as shown in Fig. The direction of the directing angle of the optical bench 10 with respect to the longitudinal direction of the optical bench 10 can be changed in accordance with the upward, downward, leftward, and rightward movement.

The optical bench controller 151 is a control board that can move up and down and right and left like a steering wheel of a flying object, and can detect a change amount of a motion. Therefore, the moving operation of the optical bench 10 is performed to control the directivity angle of the optical bench 10 according to the amount of change in the movement. When the trainer of the simulation adjusts the optical disc controller 151 vertically and horizontally, the directivity angle of the optical disc 10 changes, and the target training image selection module 152 changes the direction in which the directivity of the optical disc 10 The target training image in the target training image display unit 140 may be displayed so that the virtual targets located in the direction of this orientation angle can be displayed.

For reference, the coordinate system of the optical bench controller 151 is synchronized with the coordinate system of the target training image, so that the target training image can be changed according to the change of the orientation angle of the optical bench controller 151. For example, when the optical bench 10 is moved upward by one click base unit, the target training second image 35.1 degrees north of the first point, the second training target image 35.2 degrees north of the first image, Is displayed on the target training image display unit (140). Accordingly, the type and position of the virtual target can be changed according to the target training image displayed on the target training image display unit 140. [

The inertial measuring instrument 12 is attached to the optical bench 10 and measures inertia information including a steering angle and a moving velocity of the optical bench 10 in accordance with a movement operation of the optical bench 10. Generally, an inertial measurement unit (IMU) is an electronic device that measures the acceleration and the rotational motion of a flying object, and measures and records the speed, direction, and gravity of the flying object. Analyze. In the embodiment of the present invention, the inertia measuring device 12 is attached to the optical bench 10, and the acceleration and the direction of the movement of the optical bench 10 are measured to calculate the position coordinates of the detected virtual target.

The virtual target position extraction module 153 extracts the position coordinates of the selected detection virtual target after selecting the detection virtual target to attack from the virtual targets in the target training image in the direction of the direction of the optical axis 10 . Detection The virtual target selection is the selection of the detected target to be attacked from the trainee. A selection means for sequentially selecting virtual targets appearing in the target training image may be provided in the optical bench controller 151 so that the trainee can select the detected virtual target through the selection means of the optical bench controller 151

The computation of the position coordinates of the detected virtual target uses the inertial information measured by the inertial measuring unit and the composite navigation information according to the virtual navigation to calculate the position coordinates of the detected virtual target. For example, if the X and Y coordinates of the flight object at the start of the simulation of the virtual flight are 37 degrees north latitude, 145 degrees east longitude and 150 meters high altitude, operation of the optical bench 10 is generated, The orientation angle of the optical bench 10 is generated and the coordinates of the detected virtual target can be calculated by utilizing the orientation angle of the optical bench 10 and the coordinates of the virtual flight. Once you know the orientation angle and the longitude, latitude, and altitude coordinates of the virtual object, you can see the location coordinates of the virtual target by triangulation.

Although various information can be used for this compound navigation information indicating the coordinates of a virtual air vehicle, GPS navigation information having longitude, latitude, and altitude information can be utilized. Generally, since GPS navigation information is mainly used at the time of arming helicopter operation, GPS navigation information having GPS unit coordinates is utilized as compound navigation information in the simulation implementation of the present invention. In addition, information of INS (Inertial Navigation System) can be utilized as compound navigation information.

On the other hand, the target acquisition simulation may further include a virtual target distance calculating unit (not shown) for calculating the distance of the detected detected virtual target. As shown in FIG. 6, when the position coordinates of the virtual air vehicle, the altitude of the virtual air vehicle (virtual altitude), and the position coordinates of the detected virtual target are known, the distance from the virtual air vehicle to the detected virtual target is calculated can do. The distance of the detected virtual target can be used for the virtual launch condition at the time of the virtual weapon launch.
