Optimized Design of an Adaptive UAV Infrared Image Fusion Algorithm Based on Adversarial Game Strategy
针对无人机(Unmanned Aerial Vehicle,UAV)在复杂环境下红外-可见光图像融合存在的实时性不足、目标特征易丢失及背景伪影难抑制等问题,本文提出一种基于对抗博弈策略的无人机红外图像自适应融合算法.模型以轻量级 RFN-Nest 为骨干,构建生成器-判别器对抗框架,生成器利用通道-空间双重注意力实时加权红外热目标与可见光纹理;判别器基于真实融合图像监督全局真实性;并用红外统计掩码加权损失强化弱小热目标,实现 20 M 参数下的高精度实时融合,适合边缘设备部署.实验在 TNO公开数据集上与次优方法相比,熵(Entropy,EN)提高 1.8%,标准差(Standard Deviation,SD)提高 5.1%,互信息(Mutual Information,MI)提高 5.0%;同时将伪影评估因子(non-artifact blur factor,Nabf)降低 9.4%,多尺度结构相似性(Multi-Scale Structural Similarity,MS-SSIM)提升 0.7%,验证了算法的显著优势.
To address the challenges of insufficient real-time performance,loss of target features,and difficulty in suppressing background artifacts during unmanned aerial vehicle(UAV)infrared-visible image fusion in complex environments,an optimized adaptive fusion algorithm based on adversarial game strategies was proposed in this study.Built on the lightweight RFN-Nest backbone,the method established a generator-discriminator adversarial framework.The generator employed channel-spatial dual attention to dynamically weight infrared thermal targets and visible textures in real time,whereas the discriminator supervised global realism with real fused images.Furthermore,an infrared-statistics-based mask weighted loss was introduced to enhance weak thermal targets,achieving high-precision real-time fusion within 20 M parameters and enabling deployment on edge devices.On the public TNO dataset,compared with the second-best method,ROIMaskCNN,the proposed approach increased entropy(EN)by 1.8%,standard deviation(SD)by 5.1%,and mutual information(MI)by 5.0%;additionally,it reduced the non-artifact blur factor(Nabf)by 9.4%and improved multi-scale structural similarity(MS-SSIM)by 0.7%,demonstrating clear superiority.
