Remote sensing image semantic segmentation method and device

The invention relates to a remote sensing image semantic segmentation method and device. The method comprises the steps of obtaining a to-be-segmented remote sensing image; inputting the to-be-segmented remote sensing image into a pre-established self-attention multi-scale feature aggregation network, and obtaining an initial prediction result of the to-be-segmented remote sensing image output bythe pre-established self-attention multi-scale feature aggregation network; up-sampling the initial prediction result of the remote sensing image to be segmented to the image size of the remote sensing image to be segmented, and obtaining the final prediction result of the remote sensing image to be segmented; according to the method provided by the invention, the association between modal features and spatial information can be effectively enhanced, the multi-scale target downward text information perception capability is improved, and a finer semantic annotation result is obtained. 本发明涉及一种遥感图像语义分割方法及装置，包括：获取待分割遥感图像；
