The visible ray of the present invention and IR image enhancement system and method can be widely applied to Aeronautics and Astronautics and military use mould
Intend in device.Such as, image generating technologies is applied to military drilling simulation, the limit of time, environment, region can be overcome
System.At any time, any region, can conscientiously experience real battlefield surroundings.Military instruction for particular task
Practicing, the face under particular circumstances that generally requires is carried out, and this specific battlefield environment is the most likely difficult to obtain.Ratio
As said, specific battlefield is trained, and the soldier of a state cannot enter the military manor of another country in the case of without permission and enter
Row is familiar with the training of environment, and some military flights training must be carried out below specific weather conditions and terrain backgrounds.
These all bring significant limitation to military training.But by Virtual Simulation, by computer scene simulation
Method sense of reality ground show training environment, soldier can be allowed to accept the training under various environmental condition at any time.
Below with flight simulation operation as embodiment, it is implemented as follows:
First, after host computer system 1 collects the analogue signal of the analog capsule cabin that stick is passed back, with each second
The frequency collection data of 100 times, generate the data such as the position coordinates of aircraft, state of flight, are then sent to visual simulation system
System 2；Secondly, the control program of visual simulation system 2 forwards the data to visible ray module 3 and infrared module 4, it is seen that
Optical module 3 makes corresponding reaction according to the data scene received and aircraft viewpoint, and the flying height of aircraft is returned
To the control program of visual simulation system 2, after visual simulation system 2 receives altitude data, by flying height number
According to being sent respectively to main control computer 1 and infrared module 4, main control computer 1 calculates aircraft according to the height value returned
State of flight and display instrument table status.Owing to infrared module 4 itself can not gather the altitude information of aircraft itself, but
According to infrared module 4 and the concordance of visible ray module 3 ground scape data base, use the number that visible ray module 3 is collected
It is feasible according to the state of flight determining aircraft.In order to reach real-time effect, it is desirable to the communication speed of communication two party is
Few at 60 times per second, thus ensure visible ray module and the concordance of infrared module flight.
The combination of visible ray and infrared image Real-time Generating Technology and Virtual Simulation will be 21 century Weapon System Development and
One important means of army building.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
