Technical Problem

[0003]现有的林火识别方法大多依赖单一可见光图像进行识别，易受云雾、霾、以及光照变化等因素干扰，将非火情目标误判为烟火，识别精度难以满足实际森林防火监测的需求

Benefits of technology

本申请实施例通过多尺度特征提取，可以同时捕捉小尺度远距离火点、烟雾与大面积火情的特征，避免因单一尺度特征提取不足导致的漏检。在此基础上，对每个尺度的特征图执行全局平均池化后，再进行特征拼接与卷积压缩，得到场景融合特征向量，能有效整合各尺度场景信息，剔除冗余干扰，强化火情特征的表征能力。将场景融合特征向量输入全连接层进行非线性变换，再经归一化层输出各尺度特征图对应的动态权重，基于动态权重对多尺度特征图进行加权求和，能够实现依据当前场景内容，自动强化对火情判别更有价值的尺度特征，弱化背景干扰较强的尺度特征，得到融合了多尺度优势信息的融合特征图。最后将融合特征图输入三个检测分支，分别独立完成目标定位、类别判断与置信度评估，可以减少定位偏差与类别误判。
