摘要
在海洋军事领域,基于物理模型的烟幕仿真一直是各国学者研究的重点对象。针对物理模型中网格划分效率过慢的问题,提出了基于BVH树的空间组织方式,并采用遮挡剔除优化渲染速度。此外为了解决环境对烟幕仿真的影响,建立了海面舰船红外辐射的传输模型,实现了舰船与海面穿过大气与烟幕到达探测器并成像的全链路建模。最终经过实验,空间优化后的烟幕仿真效率得到了大幅提升,并针对烟幕干扰的效果提出了评价指标,分别对烟幕仿真的图像与红外辐射计算做出了定量分析。
In the military field,smoke screen simulations based on physical models have always been a focal point of research for scholars around the world.Addressing the issue of slow mesh division efficiency in physical models,a spatial organization meth-od based on BVH trees is proposed,along with occlusion culling to optimize rendering speed.Additionally,to address the impact of the environment on smoke simulation,a transmission model of infrared radiation from naval ships on the sea surface is established.This model enables full-chain modeling of the journey from the ship and sea surface through the atmosphere and smoke to the detec-tor and image formation.After experimentation,the smoke simulation efficiency is significantly improved with spatial optimization,and evaluation metrics for the effectiveness of smoke interference are proposed.Quantitative analyses of both the smoke simulation imagery and infrared radiation calculations are conducted.
