Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present invention, and the embodiments can be mutually combined and referred to without contradiction.
A first embodiment of the invention relates to an aircraft visual simulation method. The specific flow is shown in figure 1.
Step 101: pose information of a target aircraft is obtained, 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 the high-speed reflection memory; the pose 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 a center. In practical applications, because the obtained pose information of the target aircraft is obtained under different coordinate systems, the obtained pose information of the target aircraft needs to be converted in the subsequent view simulation.
In one example, the high-speed reflective memory board card can be used for communication, an optical fiber is used as a transmission cable, and the 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 virtual coordinates corresponding to the position coordinates in a preset three-dimensional scene model.
Specifically, the position coordinates of the aircraft obtained in step 101 are values in a coordinate system with the earth as a center, and when the corresponding view is generated, the simulation is performed by using a coordinate system in a three-dimensional scene, wherein the coordinate system in the three-dimensional scene is three axes of a three-dimensional coordinate system with the emission point of the aircraft as an origin and the three directions of the north, the east and the tangential plane of the earth as three axes. Therefore, the obtained position coordinates of the target aircraft need to be converted, and virtual coordinates in a preset three-dimensional scene model are correspondingly obtained, namely, the position coordinates are converted into corresponding virtual coordinates according to a preset coordinate conversion strategy.
In practical application, an open source graphic engine or a three-dimensional game engine can be adopted for development, such as Unity3D software, wherein a preset coordinate conversion strategy is set in the Unity3D software, and a researcher in the field can directly acquire and use the acquired position data of the target aircraft, specifically, the acquired position data of the target aircraft is subjected to proper scaling treatment and converted into position and posture data in a Unity3D coordinate system.
The preset three-dimensional scene model can be developed in advance by using three-dimensional modeling software, such as 3ds Max software development, the generated three-dimensional scene model is stored into a fbx file format supported by Unity3D (a file format of the three-dimensional model), the generated fbx file format is imported into Unity3D, coordinate point unification, coordinate axis unification and other editing work is performed, and then the generated fbx file is stored into a prefab file for repeated calling and use in a visual database. In practical application, a pre-stored three-dimensional scene model of a scene database is established, firstly, the position, the range, the attribute and the like of the model are determined according to 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 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 the functions and performances specified by the system, and if the visual simulation environment does not meet the requirements, revising the model by using the modeling tool again until the requirements are met.

Specifically, a preset target view database stores dynamic views corresponding to each virtual coordinate in the three-dimensional scene model. And (3) inquiring a view database according to the virtual coordinates obtained by conversion in the step (102), comparing the virtual coordinates with the coordinates of the preset three-dimensional scene one by one, and calling the corresponding dynamic view in the 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 acquired, 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 devices are generally used to increase the quality and fidelity of the image. The performance of the visual display system influences the reality of the visual system to a great extent and even influences the whole visual simulation effect. The technical indexes such as the angle of view, brightness, contrast and the like are mainly determined by the part of the system, and the depth sense and the immersion sense of the system are directly influenced.
In practice, the corresponding display mode may be selected according to a simulation scene or the like. For example, four modes including Virtual image display, spherical real image display, plate type display, and Virtual Reality (VR) display can be selected. The virtual image display is formed by utilizing the principle of infinite imaging of a spherical reflector, and comprises a projector, a rear projector and a spherical collimating mirror, an operator can see a virtual image of a visual image through the collimating mirror, the depth sense of the image presented by the virtual image display technology is strong, but the vertical viewing angle is smaller and is generally about 45 degrees due to the limitation of a hardware structure; the depth sense of the spherical screen real image display image is weaker than that of the virtual image display, but the pilot's angle of view is ensured to be large enough, and the spherical screen real image display image has higher image definition; the plate type display is generally realized by splicing a plurality of display screens, and can be output by a projector, so that the field of view range can be enlarged to a very high degree, and the image is relatively clear, but gaps exist among the plates, and the visual effect is affected; VR displays are displayed in a manner of imaging by using wearable VR glasses or helmets, and have a large angle of view and low cost.
Therefore, according to the first embodiment of the invention, through receiving the flight track data of the target aircraft in real time, determining the virtual coordinates corresponding to the coordinate positions of the target aircraft in the preset three-dimensional scene model, searching the corresponding dynamic view in the preset target view library for playing according to the virtual coordinates, so that the viewpoint positions can be dynamically updated, the real scenes corresponding to the appointed scene outside the aircraft can be drawn in real time, and displayed, and operators can feel the visual influence caused by the change of the external vision of the aircraft along with the change of the gesture and the speed in the flight process.
