基于翼龙2的视景仿真研究

Research on Visual Simulation Based on Wing Loong 2

传统的视景仿真中,采用通用化的模块进行仿真,不同时刻的场景差别不大,很难达到特定飞行训练科目的场景要求。针对飞行训练中不同故障的烟雾特点,采用LOD模型进行对象的创建与PSO算法进行粒子全周期的模拟,增加了视景仿真的真实感。实验结果表明该算法真实地展现了烟雾发生、发展与消散的全过程。该算法可以满足特定飞行科目下对于火焰与烟雾的模拟效果,并且通过相应参数的更改也可应用于多种训练场景。

In the traditional visual simulation,the general module is used for simulation,the scene at different times is not different,and it is difficult to meet the scene requirements of specific flight training subjects.According to the smoke characteristics of different faults in flight training,LOD model is used to create objects and PSO algorithm is used to simulate the whole cycle of particles,which increases the realism of visual simulation.Experimental results show that the algorithm truly shows the whole process of smoke generation,development and dissipation.The algorithm can meet the simulation effect of flame and smoke under specific flight subjects,and can also be applied to a variety of training scenarios through the change of corresponding parameters.
