  • 多帧对齐加可学习门控机制,有效保留相关时序信息
  • 在真实无人机数据集上显著提升目标检测准确率

无人飞行器(UAV)在灾害响应、交通监控等场景中至关重要,但其航拍视频常因快速机动、振动和镜头晃动导致严重运动模糊,严重影响目标检测等下游任务。本文旨在提出一种计算高效且有效的视频去模糊方法,以提升无人机目标检测性能。为降低计算开销,我们提出自适应潜空间选择器,根据无人机运动强度动态调整潜空间分辨率,平衡细节保留与推理效率。为保证时序一致性,引入多帧对齐与可学习门控模块,对前序帧进行形变校准并筛选有效信息,仅融合相关特征,抑制错位或无意义特征。实验表明,该方法能有效从无人机视频流中恢复清晰细节。在真实无人机基准数据集上的大量测试显示,本方法不仅去模糊效果更优,还显著提升目标检测准确率,适用于高鲁棒性空中视觉任务。

原文摘要 · Abstract (English)

Unmanned Aerial Vehicles (UAVs) play a crucial role in various scenarios ranging from disaster response to traffic surveillance. However, aerial video footage often suffers from severe motion blur due to rapid flight maneuvers, vibrations, and camera panning, which can significantly degrade downstream tasks such as target detection. Our goal is to explore a computationally-efficient and effective video deblurring approach to enhance UAV target detection performance. To reduce computational cost, we first propose an Adaptive Latent Scale Selector that dynamically adjusts the latent space resolution according to the intensity of UAV motion, thus balancing detail preservation with inference efficiency. To ensure temporal consistency, we introduce a Multi-Frame Alignment and Learnable Gating module to warp and gate the preceding frames, allowing the model to fuse only relevant temporal information and suppress misaligned or uninformative features. Our method can effectively recover sharp details from the UAV video stream. Extensive experiments on real UAV benchmarks demonstrate that our method not only yields superior deblurring performance but also significantly boosts target detection accuracy, making it highly applicable to robust aerial vision tasks.
