【摘要】 针对红外探测器系统引入的渐晕、空间滤波和非均匀性等物理效应,采用像素处理方法和调制传递函数对上述效应进行有效建模。根据模型,利用纹理生成器将效应对应的数组转换成纹理,在场景高速渲染阶段,利用OGRE渲染引擎中的合成器对上述纹理进行采样处理,从而实现在GPU中对上述效应进行高速渲染。更多还原

【Abstract】 Vignetting,spatial filtering,and nonuniformity introduced in the infrared imaging sensor are modeled,by the pixel processing method and modulation transfer function (MTF) respectively.On the basis of the above physical effects model,their corresponding textures are generated by adopting the texture generator.Finally,these physical effects texture are sampled and post-processed through the OGRE rendering engine,and high-speed real-time physical effect rendering are implemented.更多还原
