Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the invention relates to an aircraft vision simulation method. The specific flow is shown in figure 1.
Step 101: acquiring pose information of a target aircraft, wherein the pose information comprises position coordinates of the target aircraft.
Specifically, in order to ensure real-time performance, the pose information of the simulated aircraft sent by the upper computer of the platform is received through a high-speed reflection memory; the position and attitude information of the aircraft comprises position coordinates of the aircraft, and three parameters of longitude, latitude and altitude of the aircraft in the position coordinates are absolute position coordinates of the aircraft, and the absolute position coordinates are determined on an earth coordinate system with the earth as the center of gravity. In practical application, the acquired pose information of the target aircraft is obtained under different coordinate systems, so that the acquired pose information of the target aircraft needs to be converted in subsequent visual simulation.
In one example, the high-speed reflection memory board card can be used for communication, optical fibers are used as transmission cables, and flight pose information such as longitude and latitude of the aircraft transmitted by the upper computer of the platform is received, wherein the target aircraft can be simulated by a simulink model.
Step 102: and determining a virtual coordinate corresponding to the position coordinate in a preset three-dimensional scene model.
Specifically, the aircraft position coordinates obtained in step 101 are values in a coordinate system with the earth as the origin, and when generating the corresponding view, the simulation is performed using the coordinate system in the three-dimensional scene, where the coordinate system in the three-dimensional scene uses the launch point of the aircraft as the origin, and three directions of the north, east, and earth tangent plane of the launch point are three axes of the three-dimensional coordinate system. Therefore, the obtained position coordinates of the target aircraft need to be converted, and virtual coordinates in the preset three-dimensional scene model are correspondingly obtained, that is, the position coordinates are converted into corresponding virtual coordinates according to a preset coordinate conversion strategy.
In practical applications, an open source graphics engine or a three-dimensional game engine may be used for development, such as Unity3D software, where a preset coordinate transformation policy is set in the Unity3D software, and researchers in the field may directly obtain and use the coordinate transformation policy, specifically, perform appropriate scaling processing on the obtained position data of the target aircraft, and transform the position data into position and attitude data in a Unity3D coordinate system.
The preset three-dimensional scene model may be developed in advance using three-dimensional modeling software, for example, 3ds Max software is used for developing, the generated three-dimensional scene model is saved in a fbx file format (a file format of a three-dimensional model) supported by Unity3D, the generated file in the fbx file format is imported into Unity3D, and after editing operations such as coordinate point unification and coordinate axis unification are performed, the file is saved as a prefab file and is repeatedly called and used in a scene database. In practical application, the pre-stored three-dimensional scene model of the scene database is established, the position, the range, the attribute and the like of the model are determined according to the application requirements of each scene, the planning work of the model is completed, then the required original data source is determined and obtained according to the model planning, and the required original data source is processed and optimized to meet the modeling requirement. And importing the original data source into a database modeling tool to complete the establishment and synthesis of the site model, importing the established visual database into a visual simulation environment to verify whether the visual simulation environment can meet the requirements of functions and performances specified by the system, and if not, correcting the model by using the modeling tool again until the model meets the requirements.
Step 103: and searching a dynamic view corresponding to the virtual coordinate in a preset target view database and playing the dynamic view.
Specifically, a preset target view database stores dynamic views corresponding to each virtual coordinate in the three-dimensional scene model. And inquiring a view database according to the virtual coordinates obtained by conversion in the step 102, comparing the virtual coordinates with the coordinates of a preset three-dimensional scene one by one, and calling a corresponding dynamic view from a target view database when the virtual coordinates are consistent with the coordinate values corresponding to the three-dimensional scene of the view database.
After the corresponding dynamic view is obtained, the digital video information is generated and converted into an optical image which can be perceived by human eyes, and when the view is displayed, some necessary optical equipment is usually used for increasing the quality and the fidelity of the image. The performance of the view display system greatly affects the reality of the view system, and even affects the simulation effect of the whole view. The technical indexes such as the field angle, the brightness, the contrast and the like are mainly determined by the partial system, and the technical indexes directly influence the depth feeling and the immersion feeling of the system.
In practice, the corresponding display mode may be selected according to a simulation scenario or the like. If the method can select the following four modes, namely Virtual image display, spherical screen real image display, plate type display and Virtual Reality (VR) display. The virtual image display is based on the principle of infinite imaging of a spherical reflector and consists of a projector, a rear projector and a spherical collimating mirror, an operator sees a virtual image of a scene image through the collimating mirror, the depth of the image presented by the virtual image display technology is strong, but the vertical field angle of the virtual image display technology is small and is generally about 45 degrees due to the limitation of a hardware structure; the depth sense of the displayed image of the real image of the dome screen is weaker than that of the displayed image of the virtual image, but the enough large field angle of a pilot can be ensured, and the high image definition can also be considered; the plate type display is generally realized by splicing a plurality of display screens, and can also be output by a projector, the field of view can be enlarged to a very high degree, the image is relatively clear, but gaps exist among the plates, and the visual effect is influenced; the VR display utilizes a display mode of imaging by using wearable VR glasses or a helmet, and has a large field angle and low cost.
Therefore, the first embodiment of the invention receives the flight trajectory data of the target aircraft in real time, determines the virtual coordinate corresponding to the coordinate position of the target aircraft in the preset three-dimensional scene model, and searches the corresponding dynamic view in the preset target view library for playing according to the virtual coordinate, so that the viewpoint position can be dynamically updated, the real scene corresponding to the specified scene outside the aircraft can be drawn in real time and displayed, and the operator can feel the change of the vision outside the aircraft caused by the change of the attitude and the speed in the flight process and feel the visual influence caused by the change of different scenes.

The second embodiment is substantially the same as the first embodiment, and the main improvements are: in the second embodiment of the invention, before the pose information of the target aircraft is acquired, the preset scene requirement is acquired, the scene requirement is converted into the view parameter according to the preset parameter conversion strategy, and the view parameter is acquired to meet the requirement of three-dimensional scene modeling and ensure that the subsequently called three-dimensional scene meets the user requirement.

And then rendering the obtained dynamic view according to the view parameters obtained in the step 201, adopting a database paging scheduling strategy during rendering, calling in scene data of a corresponding area in real time according to the viewpoint requirement, and transmitting video information obtained after rendering to optical equipment for demonstration and playing.
In yet another example, the plug-in tools WorldComperser and TerrainComperser from Unity3D may be used to render the production. The World Composer generates real Terrain by importing real map satellite data, and uses Terrain Composer to perform beautification work such as texture addition, Terrain and landform and the like on the Terrain on the basis, and in addition, writes shaders (shaders for defining the mode of graphic hardware calculation and image output) by programming a Unity3D Shader Lab (a package interface of Unity3D to the Shader language and used for writing a Shader script under a Unity development environment) to realize a volume cloud effect and simulate the high-altitude flight scene of a target aircraft.
The actual rendering operation can also render ambient light, visibility, horizon and the like so as to enhance the realistic experience. Specifically, the Unity3D software can be used for setting and simulating ambient light, light sources comprise sunlight, point light sources and the like, the illumination and the angle of the light sources are controllable, and the lighting angle change effect of the light sources is reflected in a visual picture; corresponding visibility can be set according to different scenes, and when the corresponding coordinate position is changed, visibility change and influence on the visibility change can be displayed for all the characteristics on the visual scene picture; in addition, the horizon under all ambient lighting conditions can be simulated, and all features on the scene can exhibit distance-dependent fading effects.

In practical application, an operator can adjust parameters in real time in the simulation process and research the influence of different parameter changes of the aircraft on the model and the control algorithm.
In the embodiment, the preset scene requirements are acquired and converted into the scene parameters required by the three-dimensional scene modeling, and the scene parameters are processed and optimized to meet the requirements of the three-dimensional scene modeling, so that the subsequently called three-dimensional scene meets the requirements of users; and calling a corresponding dynamic view through the processed virtual coordinate, rendering the dynamic view according to the view parameters, and then playing the dynamic view, so that the visualization of the flight process of the target aircraft is realized, and the intuitiveness of the simulation result is enhanced. In addition, the specific digital result and the plan are generated to be used for a user to check and research, so that the user can know the flight data more accurately. The method in the second embodiment of the invention can improve the simulation reliability of the aircraft flight control system in the initial development stage and shorten the research period.
