Abstract

The invention discloses a real-time battlefield simulation system and method based on OpenSceneGraph. The simulation system includes a model building module for generating situation elements in the battlefield environment; an environment simulation module for simulating the battlefield environment, and the environment simulation module The module includes: a terrain simulation unit, which is used to perform terrain simulation according to the terrain database generated by the elevation file; a weather simulation unit, which is used to calculate the position of the sun at different periods to obtain the color and intensity of the light in the corresponding period, and at the same time, Render it on the sky according to the sky environment under different weather conditions to be simulated. The purpose is to provide a real-time battlefield simulation system and method based on OpenSceneGraph with realistic terrain and weather simulation effects.

Description

technical field [0001] The invention relates to the field of real-time battlefield simulation, in particular to a real-time battlefield simulation system and method based on OpenSceneGraph. Background technique [0002] The visualization of the battlefield situation is to dynamically display the situation subjects existing in the battlefield (including personnel, weapons and equipment, a certain military indicator or events in the battlefield) on the graphics terminal. In the user window, specific military symbols are used to indicate the subject of the situation, such as attack direction, assembly area, maneuvering route, etc. [0003] However, the existing battlefield situation visualization technology does not have a clear division of functions and cannot achieve functional modularization, resulting in repeated development of the same functional modules in different projects, resulting in long development time and high cost investment. [0004] Secondly, the simulation o...
