摘要
高精度实时弹目偏差测量是提升现代火力打击系统命中精度与闭环校射能力的关键技术。然而，现有方法普遍存在实时性差、精度低和环境鲁棒性不足等问题。为此，提出一种基于YOLO-EfficientNet的双阶段深度学习框架，实现弹目目标的快速检测与偏差精准回归。在目标检测阶段采用轻量化改进的YOLOv11网络实现弹目区域的实时鲁棒检测；在偏差回归阶段通过嵌入坐标注意力机制的剪枝版EfficientNetV2网络，实现亚像素级偏差回归；设计标准化感兴趣区域生成机制，抑制背景干扰，增强模型在复杂环境下的稳定性。实验结果表明：改进模型在检测任务中的mAP50-95达到82.6%，回归任务均方误差低至0.1683，并且整体网络帧率达107.9 FPS，有效满足了弹目偏差测量任务的实际需求，提供了一个新的弹目偏差测量范式。
Abstract
High-precision real-time projectile-target deviation measurement is a key technology for enhancing the hit accuracy and closed-loop fire correction capability of modern fire strike systems. However
existing methods generally suffer from poor real-time performance
low accuracy
and insufficient environmental robustness. To address these issues
this paper proposes a two-stage deep learning framework based on YOLO-EfficientNetfor rapid detection of projectile-target regions and accurate deviationregression.First
in the target detection stage
a lightweight improved YOLOv11 network is employed to achieve real-time and robust detection of the projectile-targetregion.Second
in the deviation regression stage
a pruned version of the EfficientNetV2 network embedded with a coordinate attention mechanism is utilized to accomplish sub-pixel-level deviationregression.Third
a standardized Region of Interest generation mechanism is designed to suppressbackground interference and enhance model stability in complex environments. Experimental results demonstrate that the improved model achieves an mAP50-95 of 82.6% in the detection task
a mean square error as low as 0.1683 in the regression task
and an overall network frame rate of 107.9 FPS. This effectively meets the practical requirements of projectile-target deviation measurement tasks and provides a new paradigm for projectile-target deviation measurement.
