遥感影像变化检测在国土调查更新、城市发展监测与规划等方面中具有重大的应用需求。针对遥感影像变化检测在实际应用中面临的挑战,文章提出了一种结合孪生倒残差结构与自注意力增强的轻量级变化检测方法。该方法通过引入孪生的改进型倒残差结构替代传统卷积神经网络结构作为骨干网络,充分提取特征信息且大幅降低网络复杂度,使用自注意力增强模块提升网络的全局信息关注能力,在损失函数中加入边缘权重精准优化提取结果的细节,利用多层次的跳接残差连接充分融合全局与局部特征。在公开和自制的遥感影像变化检测数据集上对该方法分别进行性能测试,结果表明,所提方法相较于其他变化检测方法,在不降低检测精度的前提下大幅减少了网络参数量和计算量,实现了遥感影像变化检测模型轻量化。

Change detection based on remote sensing images holds significant application potential in land source survey updating, and urban development monitoring and planning. Concerning the challenges of change detection based on remote sensing images in practical applications, this study proposed a lightweight change detection method combining the siameseinverted residual structure with self-attention enhancement. Instead of the traditional convolutional neural network structure, the siamese improved inverted residual structure was used as the backbone network to fully extract the feature information and significantly reduce the network complexity. The self-attention enhancement module was employed to improve the network's ability to pay attention to global information. Edge weights were added to the loss function to precisely optimize the details of the extraction results. The multilevel hopping residual connections were applied to fully integrate the global and local features. Finally, the performance of the proposed method was tested on the public and prepared datasets of remote sensing images for change detection, respectively. The results indicate that compared to other change detection methods, the proposed method significantly reduced network parameters and computational complexity while maintaining the detection accuracy, contributing to lightweight models of change detection based on remote sensing images.
