摘要

摘要: 装甲目标自动检测一直是红外制导领域的研究热点与难点。解决该问题的传统方法是提取目标的低层次特征，并对特征分类器进行训练。然而，由于传统的检测算法不能覆盖所有的目标模式，在实际应用中的检测性能受到限制。本文受边缘感知模型的启发，提出了一种基于边缘感知的改进深度网络，该网络是通过边缘感知融合模块提升装甲轮廓精度，利用特征提取模块和上下文聚合模块的优势，能够更好地适应目标的形态变化，具有较高的检测与识别的精度。验证结果表明，本文提出的装甲检测网络模型可以有效地提高红外图像中装甲的检测与定位精度。

Abstract: Automatic detection of armored targets has always been the most challenging problem in the field of infrared guidance. Traditional models address this problem by extracting the low-level features of an object and then training the feature classifier. However, because traditional detection algorithms can not cover all object patterns, the detection performance in practical applications is limited. Inspired by the edge-aware model, this study proposes an improved deep network based on edge perception. The network improves the accuracy of the armored contour through an edge-aware fusion module. By exploiting he advantages of the feature extraction module and context aggregation module, it can better adapt to the shape changes of objects and has high detection and recognition accuracy. The results show that the proposed armored detection network model can effectively improve the accuracy of detection and positioning in infrared images.
