The invention provides a remote sensing image semantic segmentation method based on context information and an attention mechanism. For a to-be-labeled high-resolution remote sensing image, data preprocessing and data amplification are firstly carried out, and then the amplified data is used for training a remote sensing image semantic segmentation model. In the training process, preliminary features are extracted from the image through a backbone network, then multi-scale features are extracted and fused through a multi-scale context information module, then features of different levels are combined with an attention fusion module, and finally bilinear interpolation up-sampling is directly utilized to obtain a final segmentation result. For an unlabeled image, firstly the unlabeled imageis segmented into small image blocks, the small image blocks are input into a semantic segmentation network to obtain a corresponding result, and then the small image blocks are spliced to obtain a final large-size segmentation result graph.
