随着计算机仿真技术的发展,由于具有抗干扰、低成本、高可靠性等特点,红外成像技术已经成为红外成像研究领域中一种强有力的技术研究手段,可广泛地运用于目标探测识别、武器装备研制、操作员训练等多个方面。本文针对红外传感器频域物理效应的建模与仿真,提出了一种基于GPU的改进图像卷积算法用于实时红外图像生成,在GPU顶点处理器和片段处理器实现算法的并行处理。通过与采用调制传递函数法实现的频域效应仿真结果进行对比分析,证实了此方法既可保证多种频域物理效应影响下红外图像的仿真精度,又大幅提高了渲染效率。
With the development of computer simulation technology, infrared imaging technology has become a powerful technology research method in the field of infrared imaging due to its characteristics of anti-jamming, low cost and high reliability. It can be widely used in target detection and recognition, Weapons and equipment development, operator training and many other aspects. In this paper, aiming at the modeling and simulation of the physical effects of the infrared sensor in the frequency domain, an improved image convolution algorithm based on GPU is proposed for real-time infrared image generation and parallel processing of GPU vertex processors and fragment processors. By comparing with the simulation result of frequency domain effect using modulation transfer function method, it is proved that this method can not only ensure the accuracy of infrared image under the influence of various frequency-domain physical effects, but also greatly improve the rendering efficiency.
