  • 摘要: 矿井高尘雾环境下图像去雾技术,在煤矿安全生产与自动化管理中占据关键地位。矿井作业环境特殊,深井、高温高湿区域的矿尘、粉尘与水雾易持续积累,形成高质量浓度、非均匀分布的尘雾环境。这种环境会引发强烈光散射,导致监控图像出现视距骤缩、对比度骤降、细节模糊等问题,直接干扰基于视觉的井下安全隐患识别、人员动态追踪及设备运行状态监测,制约煤矿信息化与智能化开采进程。因此,研究矿井高尘雾图像去雾技术,对保障采掘作业安全、提升自动化管理效率具有不可替代的现实意义。为深入探究矿井高尘雾环境下图像去雾算法的发展轨迹、现状及未来趋势,依据不同原理,将图像去雾算法分为图像增强、图像复原、基于融合和基于深度学习4类方法。详细阐述了各算法的发展历程,列举了其与矿井高尘雾环境图像结合的应用实例,分析了经典算法的优缺点。通过实验,对比分析并总结各类去雾算法在自然图像和矿井高尘雾图像上的优劣,试验显示,自然图像上CNN与Transformer模型性能领先,但矿井环境中CNN模型因适应性更强表现更优。同时总结了目前矿井图像去雾面临的挑战,并展望了图像去雾技术在矿井环境中的应用前景。当前面临专用数据集缺失、动态尘雾与噪声干扰、多维度退化处理难、算法需轻量化及安全特征评估标准缺乏等挑战,未来的研究应致力于开发更加鲁棒且适应性强的去雾算法,并结合矿井环境的特殊性,利用传感器融合、深度学习等先进技术提升去雾效果,同时构建真实矿井数据集,探索无监督学习,融合多源数据,优化算法实时性与轻量化,建立安全导向评估体系,推动矿井视觉监控向智能化升级。

     

    Abstract: Image dehazing technology for high-dust and foggy mine environments plays a pivotal role in ensuring safe production and automated management in coal mines. The operational environment in mines is unique; in deep shafts and areas with high temperature and humidity, mineral dust, particulate matter, and water vapor tend to accumulate continuously, creating a dense and non-uniformly distributed dusty and hazy atmosphere. This environment induces strong light scattering, leading to significant degradation in surveillance imagery, such as severely reduced visibility, low contrast, and blurred details. These issues directly impede vision-based applications like underground safety hazard identification, dynamic personnel tracking, and equipment status monitoring, thereby constraining the progress of informatization and intelligent mining. Therefore, research into image dehazing techniques for high-dust mine environments is of indispensable practical significance for safeguarding excavation safety and enhancing automated management efficiency. To provide an in-depth exploration of the development trajectory, current state, and future trends of image dehazing algorithms in such environments, this paper categorizes these algorithms into four main types based on their underlying principles: image enhancement, image restoration, fusion-based methods, and deep learning-based methods. It elaborates on the development history of each category, presents application examples in the context of high-dust mine imagery, and analyzes the advantages and disadvantages of classic algorithms. Through experiments, the paper comparatively analyzes and summarizes the performance of various dehazing algorithms on both natural and high-dust mine images. The results indicate that while CNN and Transformer models show leading performance on natural images, CNN models perform better in mine environments due to their stronger adaptability. The paper also summarizes the current challenges in mine image dehazing and discusses the future prospects of this technology. Key challenges include: the lack of dedicated datasets, interference from dynamic dust, fog, and noise, the difficulty of handling multi-dimensional degradation, the need for lightweight algorithms, and the absence of evaluation standards for safety-critical features. Future research should focus on developing more robust and adaptive dehazing algorithms. By considering the specific characteristics of the mining environment, this includes leveraging advanced technologies like sensor fusion and deep learning to improve dehazing effects, constructing realistic mine datasets, exploring unsupervised learning, integrating multi-source data, optimizing algorithms for real-time performance and lightweight deployment, and establishing safety-oriented evaluation systems to advance the intelligent upgrade of visual monitoring systems in mines.
