The Development And Research Of The Simulation System For The Performance Evaluation Of The Color Matching Of HUD

HUD(Head Up Display,HUD)is an important instrument for pilots to understand flight state parameters.It can directly add the flight state information to the external environment,and the pilots can understand the state of dynamic flight in the consideration of the external environment.Because the outside environment visual color is more complex,HUD character color is influenced by visual comparison,such as ultra low speed flight fighters in the forest such as the large green environment,green flat conventional explicit character color contrast is low,easy to cause the failure of the pilot operation.Therefore,it is possible to reduce the operating error and visual fatigue of the pilot,improve the accuracy and effectiveness of the combat task by studying the reasonable color matching of the flat display character information and changing the color of the different characters.In order to HUD information matching performance of study,design a set of flight simulation test system,by changing the color of the character information of HUD dynamic process simulation in flight,the pilot was on flat in the simulation test of information capture,easy color coordination,suitable for long time of flight,the whole picture effect were evaluated.The researchers according to the research on the performance evaluation of the pilot that the color scheme is reasonable,providing the experimental basis for the design of HUD.The test system uses OSG to develop dynamic flight scene simulation software to build a virtual flight external visual scene database,OSG provides efficient scene management and rendering optimization function,can satisfy the dynamic flight true feelings,provides a visual basis for flight simulation.Then the interface of HUD modeling software IData,the main character of the HUD information definition block and color variables,modeling after completion of loading to flight scene simulation program,with HUD as the first perspective on visual flight dynamic flight.Provide a graphical tool for rapid development of dynamic interactive IData as a set,it can quickly create instrument,and can real-time response to application variables and control events,reduce the graphics development in simulation andintegration time.Finally,the flight attitude of the JSBJim is used to calculate the attitude of the aircraft,and the aircraft’s flight trajectory is very close to the real flight state.The test results show that the pilot can feel good on the visual impact of color information in the testing process,the display quality no shake,no distortion,no obvious visual delay HUD information matching process,can fully meet the needs of the pilot test.
