Description
[0001] The present invention relates to an integrated helmet sighting device for an aircraft, and more particularly, to an HMD worn by a pilot, in which not only mission information and flight navigation related symbols but also three-dimensional electronic map images corresponding to the pilot's gazing direction and an external camera The present invention relates to an integrated helmet sighting device for an aircraft capable of providing various real time flight information to pilots by integrating external images captured in real time.
Recent development trends in developed countries have focused on enhancing the capabilities of information processing (identification, sensing, visualization) and communication (real-time data link) rather than improving aircraft performance in order to improve the success rate and survivability of pilots. have. In particular, information processing systems, except for the armed systems, tend to adopt similar generic technologies for civilian and military use.
Accordingly, various devices for information processing have been developed. Among them, a helmet mounted display (HMD) has been spotlighted as a very useful device for aircraft operation.
The HMD displays information of the aircraft on the visor or goggle of the helmet to enable the pilot to utilize the information. More specifically, the HMD provides a variety of information (flight symbols related to attack, navigation, aiming and landing modes) as a means of displaying complicated and various flight information and precise arming aiming so that the pilot can recognize the aircraft performance data at a glance Thereby minimizing unnecessary steering operations during flight.
The related art has been disclosed in Korean Patent Laid-Open Patent Application No. 2011-0034224 ("Target Coordinate Measuring System Using HI-EMD and Target Coordinate Measuring Method Using It, "
On the other hand, basically, the concept of the HMD is to provide a virtual image or path to the vision device, regardless of the direction the pilot is looking at, the symbol, the image type information and the coordinate value. FIG. 1 is an example of information displayed on a conventional helmet mount demonstrator. As shown in FIG. 1, only simple mission symbol information is provided to a see-through type panel as shown in FIG.
However, as the application range of the HMD system is gradually expanded in the development of the next generation aircraft, it is necessary to secure the accuracy of the sight data and the real-time without processing delay in order to display the real-time flight information and mission information about the pilot's gazing direction.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an airplane pilot with various information ensuring accuracy, reliability, and real- And to provide an integrated helmet sighting device for an aircraft.

Therefore, not only stable operation of civilian aircraft but also fighter aircraft, short-range missiles can be fired by capturing the enemy aircraft without changing the aircraft nodal when the enemy is detected in the lower or upper part of the flight.
In addition, conventionally, the UART signal and the video signal transmitted through the respective electrical communication lines are converted into one optical signal and transmitted and received, thereby simplifying the communication line and reducing the communication load, thereby enabling a large-capacity data communication have.
Finally, in the conventional vision device, there is a problem that accuracy of information is somewhat deteriorated by using the monocular system. However, in the present invention, by using the binocular system, it is possible to secure a wide viewing angle by controlling the bilateral superimposition, Dimensional stereoscopic images can be realized.

The present invention relates to an integrated helmet sighting device for an aircraft for displaying real-time flight information and mission information on a flight direction of an aircraft pilot, and FIG. 2 shows a schematic configuration diagram of an integrated helmet sighting device according to the present invention.

The present invention is configured as described above, thereby unifying the symbol data and the three-dimensional electronic map unlike the conventional art that merely provides symbols. Therefore, it is possible to maximize the safety and reliability of the pilot in flight and take-off and landing as the pilot can view and control the 3D electronic map securely even in difficult weather conditions such as weather or nighttime.
In addition, as shown in FIG. 2, the integrated helmet vision device according to the present invention may further include a photographing

Specifically, one image is transmitted so that one of the real-time external image or the three-dimensional electronic map image is selectively displayed according to the pilot's control, or the three-dimensional electronic map image and the real-time external image are superimposed and converted into a single image signal So that the superimposed image can be displayed on the

On the other hand, in the case of an HMD applied to an aircraft, particularly, an HMD applied to an aircraft performing a specific mission, it is very important that the accuracy of the data and the realization without delay are guaranteed.
To this end, the
In other words, the present invention is capable of real-time data processing and provides precise image and mission information corresponding to the direction of the pilot's gaze through helmet attitude tracking, so that not only stable operation of a civilian aircraft, It is possible to short-range missile shooting by capturing the enemy without altering the airplane's nodal point, thus providing the advantage of shortening the shooting time and improving the capture ability.
In addition, in the present invention, the
Since the 3D electronic map is produced using previously obtained data, when the time difference between the acquisition time and the present time of the data is large, the terrain deformation occurs and the accuracy is lowered. As a result, the risk of aircraft accidents is increased and the safety of the pilots is not ensured, resulting in massive cost loss in the event of an accident.
In the present invention, a real-time external image can be used to solve the problem of generating the error. That is, by comparing and analyzing the real-time external image and the previously stored three-dimensional electronic map image corresponding to the corresponding image, it is possible to correct the deformed portion of the electronic map topography in real time. For reference, when comparing two images for correction, it is necessary to reflect the position and attitude (angle) of the camera that captured the real time external image, so that more accurate correction will be possible.
In addition, in the present invention, the
Conventionally, there has been a problem that a communication load is generated by transmitting and receiving a UART (Universal Asynchronous Receiver / Transmitter) signal and a video signal through respective electrical communication lines.
