Problems solved by technology

[0002] At present, the visual imaging system of aviation simulators adopts a multi-channel distributed real-time rendering method. In order to realize the synchronization of special effects such as terrain, 3D clouds, dynamic ocean and wind in the multi-channel visual, it needs to consume a lot of CPU and GPU resources. At the same time, the image update rate of the aviation simulator's visual imaging system also has high requirements, so it can only be achieved by reducing the shadows, mirror images, lighting and texture details in the virtual scene, which leads to the existing visual imaging system. Cannot provide a more realistic virtual environment

Embodiment 1

[0029] This embodiment proposes a fast rendering method based on panorama pre-baking, figure 1 It is the flowchart of this embodiment. As shown in the figure, the method includes the following steps:

[0030] Step 1. The visual imaging system receives the mission data sent by the flight simulator host in real time, including: LOD strategy file, flight position, flight attitude, and flight history data.

[0031] In step 1, the flight position includes the longitude, latitude, and altitude of the flight; the flight attitude includes: three angles of the aircraft's running direction, linear velocity, angular velocity, angular acceleration, and flight vibration state.

[0032] Step 2. The visual imaging system conducts path forward-looking based on real-time flight position, real-time flight attitude, and flight history data, predicts the flight path in the future, and calculates the location and range of the preloaded area according to the predicted flight path; then uses LOD T...

Embodiment 2

[0038] This embodiment proposes a visual imaging system for implementing the method described in Embodiment 1. A common visual imaging system mainly includes an aircraft performance simulation system, an instructor platform, a three-channel graphics workstation and a display system. The three-channel graphics workstation mainly includes the hardware system of the workstation itself and the visual driver module and database deployed on these hardware. In order to realize the panorama pre-baking fast rendering method, the three-channel graphics workstation in this embodiment adopts a GPU graphics workstation with six built-in RTX2080 graphics cards, a host memory of 64G, and a Win10 64-bit operating system.

[0039] In this embodiment, the visual driver module is optimized so that it can perform scene pre-baking. Its functional architecture is as follows: figure 2 As shown, it includes: interactive scheduling engine, database deployment engine, scene deployment engine, and ren...

Abstract

The present invention proposes a fast rendering method based on panoramic pre-baking and a visual imaging system, including steps: the visual imaging system receives mission data sent by the flight simulator host in real time, and predicts the flight path in the future according to the mission data The location and range of the preloaded area to generate the forward-looking path bounding volume; according to the scene scheduling instruction received from the instructor station, the static objects and dynamic objects covered by the forward-looking path bounding volume are cached in the GPU of the imaging system from the object database. Pre-baking to obtain terrain and weather images generated by ground objects and meteorological objects with lightmap information; when flying to the location of the preloaded area, control the GPU to directly call the rendered texture information to render to the physical model of the forward-looking path bounding volume superior. The invention adopts the pre-baking technology, which can improve the real-time rendering efficiency of the virtual scene, and enhance the fidelity of image rendering under the premise of ensuring a stable image update rate.
