摘要
野生动物是自然环境的重要组成部分,保护野生动物对人类发展具有重要意义。利用红外相机与深度学习算法监测野生动物,为生物保护提供了有效途径。论文设计了一种基于YOLOv5的红外野生动物图像检测算法。在YOLOv5的颈部网络部分引入了内卷算子与特征拼接操作。改进了颈部网络的原始concat拼接操作。根据特征的重要程度对不同特征层进行加权操作,为重要特征层赋予更高的权重,使网络更加关注关键信息。改进的算法相比原始算法在各个指标方面都有大幅度提升,为野生动物检测提供了更有效的方法。
Wildlife is an important part of the natural environment,and its conservation is of great importance to human development.Nowadays,using infrared cameras with deep learning algorithms to monitor wildlife provides an effective way for biological conservation.In this paper,an infrared wildlife image detection algorithm based on YOLOv5 is designed.This paper introduces the involution operator with feature splicing operation in the neck network part of YOLOv5.The original concat splicing operation of the neck network is improved.Its weighting operation is applied to different feature layers according to the importance of the features,giving higher weights to the important feature layers and making the network focus more on the key information.The improved algorithm in this paper has substantial improvement in all metrics compared with the original algorithm,providing a more effective method for wildlife detection.
